Background technique

As described in Japanese Unexamined Patent Application Publication No. 2009-162972, there is known a multi-display device designed to use a plurality of display devices for displaying images side by side as a whole, thereby displaying more images than a single display device. Images that can display larger images. In the multiple display device described above, each of the plurality of display devices arranged side by side has a non-display area on the periphery of the display area, and the plurality of display devices are arranged so that the non-display areas overlap each other. Since the non-display areas overlap each other, there is a height difference between each display area.

However, a display device is sometimes provided with a polarizing plate on a display surface. A polarizing plate generally has an edge of a non-display area extending to the periphery of the display area. Therefore, if a display device provided with polarizing plates is arranged so that only non-display regions are overlapped in the same structure as a prior art multiple display device, the thickness of the members constituting each non-display region of the display device will increase the polarized light. The thickness of the board. In other words, only the polarizing plate is provided, and the height difference caused by overlapping of the non-display regions increases. If the level difference increases, the image processed as a whole will be recognized as discontinuous due to the level difference, and there is a problem that the image quality of the image will be adversely affected.

FIG. 1 is a diagram illustrating an example of the configuration of a display device 1 according to an embodiment of the present invention. As shown in FIG. 1 , a display device 1 is connected to a plurality of image display panels 2 (for example, image display panels 2 a , 2 b ) that display images formed by a plurality of pixels 50 . Accordingly, the display device 1 has a larger connected display area than the display area 100 in which an image is displayed by the display unit 95 of one image display panel 2 . As shown in FIG. 1 , a display device 1 has a connection display area in which four rectangular image display panels 2 are connected two by two in two vertical directions (for example, X direction and Y direction described later). Specifically, the four image display panels 2 included in the display device 1, that is, two image display panels 2a and two image display panels 2b, each have a display area 100 along two perpendicular directions, namely, the X direction and the Y direction. Connect side by side in a 2×2 configuration.

First, the image display panel 2 (image display panels 2a, 2b, 2c, 2d, 2e, 2a ₁ to 2a ₉ , 2b ₁ to 2b ₉ ) will be described. The image display panel 2 is a flat type (flat type) image display panel.

The image display panel 2 adopted by the utility model can adopt any mode for display mode. In the description with reference to FIG. 1 and the like, an image display panel using a reflective liquid crystal display panel will be described as the image display panel 2 . A reflective liquid crystal display panel may or may not have a so-called memory in pixel (MIP: memory in pixel) function.

The image display panel 2 is, for example, an image display panel that supports color display, but may also be an image display panel that supports monochrome display. An image display panel supporting color display includes pixels 50, and one unit pixel 5, which is a unit for forming a color image, functions as a plurality of subpixels. Specifically, in an image display panel supporting color display, the unit pixel 5 includes, for example, a pixel 50R displaying red (Red: R), a pixel 50G displaying green (Green: G), and a pixel 50G displaying blue (Blue: B). The three types of pixels 50 are the pixel 50B (see FIG. 5 ). Hereinafter, when described as the pixel 50 , the difference in color of the pixels 50R, 50G, and 50B cannot be recognized.

More specifically, the other pixels 50 may be, for example, pixels 50 that display white (White: W) to increase brightness, or colors corresponding to the complementary colors of RGB (for example, cyan (C), magenta (M), Pixels 50 of at least one color among yellow (Y). The color of these pixels 50 corresponds to the color of the filter 22 .

2 and 3 are cross-sectional views illustrating a schematic configuration of the image display panel 2 . As shown in FIGS. 2 and 3 , the image display panel 2 has a first panel portion (TFT substrate) 10 , a second panel portion (CF substrate) 20 , and a liquid crystal layer 30 as main components. In the second panel part 20 , the polarizer 90 is stacked on the display surface 102 of the second substrate 23 . The display surface side of the image display panel 2 is the side where the display surface 102 faces the polarizer 90 . The first panel part 10 and the second panel part 20 are arranged facing each other with a predetermined gap through a not-shown spacer. The liquid crystal layer 30 is formed by sealing a liquid crystal material in the gap between the first panel part 10 and the second panel part 20 . More specifically, the gap between the first panel part 10 and the second panel part 20 is sealed by the sealing member SE (refer to FIG. The inner seal is filled with a liquid crystal material, thereby forming a liquid crystal layer 30 .

FIG. 4 is a schematic diagram showing an example of a circuit configuration which is a main configuration of the display unit 95 of the image display panel 2 . The first panel unit 10 has a first substrate 14 made of transparent glass or the like as a substrate material, and a reflective electrode 63 formed on the liquid crystal layer 30 side of the first substrate 14 . The first substrate 14 has a circuit substrate 14a formed on the substrate and a planarizing film 14b laminated on the circuit substrate 14a. The circuit board 14a has a plurality of scanning lines 62 (62 ₁ , 62 ₂ , 62 ₃ , . . . ) and a plurality of signal lines 61 (61 ₁ , 61 ₂ , 61 ₃ , . . . ). In the following description, it may be assumed that the extending direction of the scanning lines 62 is the X direction (row direction), and the extending direction of the signal lines 61 is the Y direction (column direction). The X direction is perpendicular to the Y direction. The arrangement of the pixels 50 connected to the scanning lines 62 and the signal lines 61 is, for example, a matrix arrangement extending in the XY direction, but this is only an example of the arrangement of the pixels 50 and is not limited thereto and can be changed as appropriate.

More specifically, as shown in FIG. 4 , wiring is made on the first substrate 14 so that a plurality of scanning lines 62 and a plurality of signal lines 61 intersect. Further, on the first substrate 14 , the pixels 50 are arranged at intersection positions of the scanning lines 62 and the signal lines 61 . The plurality of signal lines 61 are wirings for transmitting signals for driving the pixels 50 , that is, video signals output from the signal output circuit 70 , to the pixels 50 for each column of pixels. The plurality of scanning lines 62 are wirings for transmitting signals for selecting the pixels 50 in row units, ie, scanning signals output from the scanning circuit 80 , for each row of pixels. Each one end of each column of the plurality of signal lines 61 is connected to an output end corresponding to the signal output circuit 70 . One end of each row of the plurality of scan lines 62 is connected to an output end corresponding to the scan circuit 80 .

The pixel 50 has, for example, a switching element 51, a liquid crystal capacitor 52, a storage capacitor 53, and the like. The switching element 51 is a switch such as a TFT (Thin Film Transistor: thin film transistor), for example. In the switching element 51 , the gate electrode is connected to one of the plurality of scanning lines 62 , and the source electrode is connected to one of the plurality of signal lines 61 .

The liquid crystal capacitance 52 refers to the capacitance component of the liquid crystal material generated between the pixel electrode (for example, corresponding to the reflective electrode 63 ) and the counter electrode formed opposite thereto (for example, corresponding to the transparent electrode 21 ). The pixel electrode is connected to the drain electrode of the switching element 51 . In the case of an image display panel supporting color display as in this embodiment, the pixel electrode corresponds to the reflective electrode 63 formed for each pixel 50 . On the counter electrode, a common potential V _COM of DC voltage is commonly applied to all the pixels. In the holding capacitor 53 , one electrode is connected to the pixel electrode of the liquid crystal capacitor 52 , and the other electrode is connected to the counter electrode of the liquid crystal capacitor 52 .

As the circuit elements, signal lines 61 and scanning lines 62 of the first substrate 14, the flattening film 14b is formed on the surface side of the wiring layer 14c (see FIG. . In addition, a reflective electrode 63 is formed for each pixel 50 on the planarization film 14 b.

The reflective electrode 63 reflects external light incident from the outside through the second panel portion 20 and the liquid crystal layer 30 . The display unit 95 of the image display panel 2 having a plurality of pixels 50 performs display output using the reflected light of the reflective electrode 63 .

Since circuit elements including TFTs are formed on the first substrate 14 , it is sometimes called a TFT substrate. The first substrate 14 of the present embodiment has a structure in which each unit is formed on a glass substrate, but a substrate using a material other than glass may also be used. In addition, a light-shielding material and a reflective material may be used for the circuit board 14a.

The second panel part 20 has a transparent electrode 21 formed of ITO (Indium Tin Oxide: Indium Tin Oxide), a filter 22, and a second panel made of transparent glass or the like from the side of the liquid crystal layer 30 toward the display surface, for example. Two substrates 23 and a polarizer 90 .

FIG. 5 is a schematic diagram showing an example of the color and arrangement of pixels 50 using the filter 22 . In the optical filter 22, for example, striped R, G, and B filters extending in the column direction (Y direction) are arranged repeatedly at the same pitch as the row direction (X direction) of the pixels 50. . Since the second substrate 23 includes a color filter (CF: Color Filter) 22 , it is sometimes called a CF substrate. Since the reflected light of the reflective electrode 63 passes through the filter 22 , it is recognized as light of a color corresponding to the color of the filter 22 . In FIG. 5 , the unit pixel 5 is constituted by a plurality of pixels 50 arranged in stripes, but the specific arrangement and shape of the pixels 50 constituting the unit pixel 5 can be appropriately changed.

In addition, it is not necessary to provide the filter 22 for all the pixels 50 . Specifically, a light shielding portion BM (see FIG. 15 ) is provided instead of the filter 22 in a part of the pixels 50 located in the vicinity of the sealing member SE. The light-shielding part BM is constituted by, for example, a light-shielding member provided so as to be continuous with the black matrix positioned between the color filters 22 of each color. The pixel 50 provided with the light shielding portion BM becomes a dummy pixel that cannot be used for display output.

The polarizing unit 90 includes, for example, a polarizing plate 26, a 1/2 wavelength plate 25, a 1/4 wavelength plate 24, and an anisotropic scattering member (LCF) 27 from the display surface side toward the opposite side (back side) of the display surface 102. . The polarizer 26 is a plate-shaped polarizer mainly composed of a resin such as polyvinyl alcohol (PVA: Poly-Vinyl Alcohol), for example. The 1/4 wavelength plate 24 and the 1/2 wavelength plate 25 are retardation plates mainly composed of birefringent materials such as crystal and mica. The 1/4 wavelength plate 24 gives a phase difference of π/2 (=λ/4) to the electric field vibration direction (polarization plane) of incident light. The 1/2 wavelength plate 25 gives a phase difference of π (=λ/2) to the electric field vibration direction of incident light. After the external light from the display surface side passes through the polarizing plate 26 and becomes linearly polarized light in a specified direction, the polarizing plane is rotated by 90 degrees through the 1/2 wavelength plate, and then becomes circularly polarized light through the 1/4 wavelength plate 24, and reaches all directions. Anisotropic scattering component 27 . Thus, the image display panel 2 has the polarizing unit 90 provided on the display surface side of the display unit 95 and including at least the polarizing plate 26 .

Fig. 6 is a cross-sectional view of an anisotropic scattering member in which external light is incident from a surface. Fig. 7 is a cross-sectional view of an anisotropic scattering member in which incident light enters from the back. FIG. 8 is a plan view showing an example of an anisotropic scattering member. FIG. 9 is a schematic diagram for explaining the function of an anisotropic scattering member. FIG. 10 is a plan view showing an example of an anisotropic scattering member. FIG. 11 is a schematic diagram for explaining the function of an anisotropic scattering member. The anisotropic scattering member 27 is a sheet-like member that scatters light. As the anisotropic scattering member 27, for example, a Light Control Film (Light Control Film) can be used.

As shown in FIGS. 6 and 7 , the anisotropic scattering member 27 includes a first region 27B and a second region 27S, and the two types of regions 27B and 27S have different refractive indices from each other. The anisotropic scattering member 27 may have a louver structure in which a plurality of plate-shaped second regions 27S are arranged at predetermined intervals in the first region 27B as shown in FIGS. 8 and 9, or may be formed in a columnar shape as shown in FIGS. The second region 27Sa is arranged in a columnar configuration in the first region 27Ba. According to the present embodiment, the first region 27B is formed using a material having a lower refractive index than the second region 27S. The first region 27B is formed using a material having a relatively low refractive index in the anisotropic scattering member 27, thereby becoming a low refractive index region. In addition, the second region 27S is formed using a material having a relatively high refractive index in the anisotropic scattering member 27, thereby becoming a high refractive index region.

The anisotropic scattering member 27 is anisotropic for scattering of light. Specifically, the anisotropic scattering member 27 is, for example, a forward scattering layer having a large amount of forward scattering and a small amount of back scattering. More specifically, the anisotropic scattering member 27 scatters light incident from a specific direction (scattering axis direction). In addition, when light is incident from a specific direction on the side of the polarizer 26 (for example, external light) due to the relationship with the second substrate 23, the anisotropic scattering member 27 transmits the incident light with little scattering, and makes the reflective electrode The light reflected back by 63 (reflected light) is largely scattered. The anisotropic scattering member 27 is configured as a surface such that the degree of change in the refractive index of light from the vicinity of the boundary between the first region (low refractive index region) 27B and the second region (high refractive index region) 27S is relatively large. When the light is incident from the side and exits from the side where the degree of change in the refractive index is relatively small near the boundary between the low-refractive index region 27B and the high-refractive index region 27S, the light is scattered.

For example, as shown in FIG. 6, when the external light L1 enters from a predetermined direction (scattering axis direction) due to the relationship with the second substrate 23, the anisotropic scattering member 27 scatters the external light L1. When L2 enters from other predetermined directions (directions other than the scattering axis direction), the external light L2 is transmitted. The anisotropic scattering member 27 transmits the external light L2 when the external light L2 is incident from another predetermined direction, and makes the light reflected by the reflective electrode 63 out of the transmitted light within a predetermined range around the scattering central axis S. scattering. The external lights L1 and L2 are parallel lights incident on the polarizing plate 26 of the second panel unit 20 . External light L1, L2 may be unpolarized light or polarized light. Also, as shown in FIG. 7, for example, when the light is incident from the side opposite to the external light L1, L2, and the incident light L3, L4 is incident, the anisotropic scattering member 27 is caused by the relationship with the second substrate 23. On the other hand, light incident from a predetermined direction (scattering axis direction) is scattered, and light incident from other directions (directions other than the scattering axis direction) is transmitted. Specifically, when the incident light L3 from a predetermined direction enters due to the relationship with the second substrate 23, the incident light L3 is transmitted, and when the incident light L4 from another predetermined direction enters, the incident light L3 is transmitted. L4 scatter. In addition, the predetermined directions of the external light L1 and the incident light L4 are only reversed by 180 degrees, but they are in the same direction. In addition, the predetermined directions of the external light L2 and the incident light L3 are only reversed by 180 degrees, but they are in the same direction. It should be noted that the scattering of light only needs to occur when the anisotropic scattering member 27 passes, and it may be scattered at the time of incidence, scattering at the time of output, or scattering along the path.

When the anisotropic scattering member 27 has the louver structure shown in FIG. 8, as shown in FIG. The diameter d1 in the longitudinal direction of the region 27B and the second region 27S is the short diameter, and the diameter d2 in the short direction (the direction in which the first region 27B and the second region 27S are arranged) of the first region 27B and the second region 27S is the long diameter. path. When the anisotropic scattering member 27 scatters the light reflected from the reflective electrode 63 , it scatters in an elliptical shape in the same manner.

When the anisotropic scattering member 27a has a columnar structure as shown in FIG. 10, as shown in FIG. Circular shapes of the same diameter. In addition, when the anisotropic scattering member 27 a scatters the light reflected by the reflective electrode 63 , it scatters the light in a circular shape in the same manner.

The anisotropic scattering member 27 is, for example, a member in which the first region 27B and the second region 27S extend in the thickness direction and are inclined in a predetermined direction. The anisotropic scattering member 27 is formed, for example, by irradiating ultraviolet rays from an oblique direction to a resin sheet which is a mixture of two or more photopolymerizable monomers or oligomers having different refractive indices. The anisotropic scattering member 27 may have a structure different from that described above, and may also be a member manufactured by a method different from that described above. The anisotropic scattering member 27 may be one layer or multiple layers. When the anisotropic scattering members 27 are multilayered, they may have structures that are equal to or different from each other. The anisotropic scattering member 27 may also be omitted.

Next, the arrangement of the polarizers 90 of the image display panel 2 (image display panels 2a, 2b) and the overlapping of the image display panels 2 (image display panels 2a, 2b) will be described. FIG. 12 is a schematic plan view of the image display panel 2 in the state where the polarizing unit 90 is not provided when viewed from the display surface side. In the following description, the portion other than the polarizing portion 90 in the configuration of the image display panel 2 is referred to as the display portion 95 . The display unit 95 includes a display surface 102 having a display area 100 and a non-display area 101 surrounding the display area 100 . Specifically, the display unit 95 uses the area where the optical filter 22 is provided as the display area 100 to display an image on the display surface side. More specifically, the display unit 95 displays an image by the pixel 50 at the position where the filter 22 is provided among the plurality of pixels 50 based on image data transmitted from an external configuration through the wiring unit 110 , for example. The display unit 95 of the present embodiment has a rectangular display area 100 and a frame-shaped non-display area 101 with four sides added to the display area 100 .

The non-display area 101 is an area located around the area where the plurality of pixels 50 provided with the filter 22 are provided on the display portion 95 . Specifically, the non-display area 101 is provided with a light shielding portion BM that blocks light between the pixels 50 and the display surface 102 to form a boundary between the display area 100 and the non-display area 101 . The pixels 50 in the non-display area provided with the light shielding portion BM are dummy pixels that cannot be used for image display. According to this embodiment, the light shielding portion BM is continuously provided outside the display area 100 of the display portion 95 to the side surface (for example, the side surface portion 106 ) which is the edge of the display portion 95 (see FIG. 15 ).

As shown in FIG. 12 , the widths of the four sides of the non-display area 101 are not necessarily the same. Specifically, for example, as shown in FIG. 12 , the widths W2 , W3 , and W4 of three sides other than the side on the wiring portion 110 side are narrower than the width W1 of one side on which the wiring portion 110 extends. Therefore, when connecting a plurality of image display panels 2, by preferentially connecting the three sides other than the side of the wiring portion 110 side, it is easier to make the non-disconnected areas between the display regions 100 of the respective image display panels 2. The width of the display area 101 is narrowed.

The image display panel 2 has a configuration in which a polarizing unit 90 is provided on a display unit 95 shown in FIG. 12 . By providing the polarizing portion 90 , the image display panel 2 is much thicker than when only the display portion 95 is provided. As a specific example, the thickness of the display portion 95 in this embodiment is about 300 μm to 1000 μm. On the other hand, the polarizer 90 has a thickness of 400 to 600 μm or more calculated from the fact that the thickness of the polarizing plate is about 400 μm. The polarizer 90 is a part of the optical system, and it is difficult to reduce the thickness.

13 and 14 are diagrams showing an example of the positional relationship between the boundary between the display area 100 and the non-display area 101 and the polarizer 90 . The polarizer 90 is provided to cover the display area 100 , and partly extends to the non-display area 101 . Specifically, as shown in FIG. 13 , the vertical and horizontal widths of the rectangular polarizer 90 are only slightly larger than the vertical and horizontal widths of the display region 100 . Therefore, the edge of the polarizing portion 90 provided to cover the display surface side of the display portion 95 extends to the non-display region 101 . As shown in FIG. 13 , by disposing the polarizer 90 in a positional relationship between the middle of the display area 100 and the middle of the polarizer 90 , each of the two opposite sides extending to the four sides of the non-display area 101 The widths of the polarizers 90 become substantially equal.

On the other hand, by adjusting the positional relationship between the display area 100 and the polarizer 90 , the width of the polarizer 90 extending to each of the four sides of the non-display area 101 can be adjusted. Specifically, as shown in FIG. 14 , for at least one of the four sides of a rectangle, by making the boundary line between the display area 100 and the non-display area 101 closer to the edge of the polarizer 90 , it is possible to further reduce the distance extending to the side. The width of the polarizer 90 in the non-display area 101 . In addition, the positional relationship between the display area 100 and the polarizer 90 can be adjusted within a range satisfying the condition that the polarizer 90 covers the display area 100 .

According to the example shown in FIG. 14, by arranging the polarizer 90 having the same vertical and horizontal width as the polarizer 90 shown in FIG. The width of the polarizer 90 is relatively reduced, which is an example of a specific method for reducing the width of the polarizer 90 extending to at least a part of the non-display region 101 . A method of making the width of the polarizing portion 90 extending to at least a part of the non-display area 101 smaller is not limited thereto. For example, by further reducing the difference between the vertical and horizontal widths of the polarizing portion 90 and the display region 100 , the width of the polarizing portion 90 extending to the non-display region 101 can be made smaller.

15 is a schematic cross-sectional view showing an example of the connection structure of the image display panels 2a and 2b and the positional relationship between the boundary between the display area 100 and the non-display area 101 and the polarizer 90 . The cross-sectional views shown in FIG. 15 and the like are merely schematic, and are not shown faithfully to the dimensions of the actual cross-sectional structure. FIG. 16 is a schematic diagram showing the positional relationship of the image display panels 2a, 2b shown in FIG. 1 . FIG. 16 shows the positional relationship when viewed from the direction of the arrow V1, with the upper side being the display side and the lower side being the rear side. A pair of image display panels connected to each other (for example, two image display panels 2 a and 2 b ) are arranged to overlap a part of the non-display area 101 . And, among the two connected image display panels 2a, 2b, one image display panel 2a is located on the display surface side of the other image display panel 2b, and the other image display panel 2b is located on the side of the one image display panel 2a. back side. Specifically, as shown in FIG. 15 , image display panel 2 a and image display panel 2 b are overlapped and connected within a predetermined width range (overlapping range W5 ) from the edge of display portion 95 . The non-display area 101 is located within the overlapping range W5. Specifically, the light shielding part BM is provided in the overlapping range W5. In other words, the display area 100 having the pixels 50 provided with the optical filter 22 is not included in the overlapping range W5.

Among the side parts of the polarizer 90 of the image display panel 2b on the rear side, the side part (side part 105) on the side of the image display panel 2a on the display side and the side part of the image display panel 2a on the display side, The side surface (side surface 106 ) on the side of the image display panel 2b located on the rear side faces each other. That is, the image display panel 2 b on the rear side does not extend to a position where the polarizing portion 90 overlaps the image display panel 2 a on the display surface side. Specifically, for example, as shown in FIG. 15 , the polarizer 90 of the image display panel 2 b does not extend to the overlapping range W5 . The polarizer 90 of the image display panel 2b shown in FIG. The polarizer 90 of the display panel 2 b covers the display area 100 , and the polarizer 90 of the image display panel 2 b is provided at a position that does not extend to the overlapping range W5 .

More specifically, the polarizer 90 of the image display panel 2b is provided at a position away from the center of the display device 1 shown in FIG. . When the position of such a polarizing unit 90 is described with reference to FIG. 14 , it is a position near the lower right side. This is because the image display panel 2a overlaps the image display panel 2a at positions corresponding to the upper and left sides in FIG. 14 in the non-display area 101 of the image display panel 2b. By disposing the polarizing portion 90 of the image display panel 2 b in this way, the degree of extension to the non-display region side where the light shielding portion BM is provided can be made smaller.

In this embodiment, the image display panel 2 a on the display surface side is in contact with the image display panel 2 b on the rear side. Specifically, by disposing the polarizers 90 of the image display panel 2 b as shown in FIG. 14 , the polarizers 90 can be placed in contact with each other without being positioned between two overlapping display portions 95 . Therefore, the thickness of the polarizing portion 90 of the image display panel 2b is not added to the thickness of the connecting portion between the image display panel 2a and the image display panel 2b. Therefore, among the thicknesses of the display device 1, the thickness of the configuration of the image display panel 2 is the sum of the thickness of the image display panel 2b, the thickness of the image display panel 2a, and the thickness of the polarizer 90 of the image display panel 2a.

According to the present embodiment, the positions in the overlapping direction of a pair of image display panels 2 approaching in an oblique direction intersecting the two directions with respect to the other pair of image display panels 2 approaching in an oblique direction are all display surfaces. side or back side. Specifically, the four image display panels shown in FIG. 1 , that is, two image display panels 2a and two image display panels 2b, are connected in a 2×2 arrangement along the X direction in the vertical direction and the Y direction in the horizontal direction. However, the two directions refer to the X direction and the Y direction. That is to say, a pair of image display panels 2 approaching in an oblique direction intersecting two directions refers to a pair of image display panels 2 a combining the upper right image display panel 2 a and the lower left image display panel 2 a shown in FIG. 1 . A display panel, and a pair of image display panels combining the upper left image display panel 2b and the lower right image display panel 2b. The upper right image display panel 2a and the lower left image display panel 2a are located on the display surface side with respect to the upper left image display panel 2b and the lower right image display panel 2b. The upper left image display panel 2b and the lower right image display panel 2b are located on the rear side with respect to the upper right image display panel 2a and the lower left image display panel 2a.

In addition, in this embodiment, as shown in FIG. 15 , the polarizer 90 of the image display panel 2 a on the display side may extend to the non-display area 101 overlapping with the image display panel 2 b on the back side.

The polarizers 90 of all the image display panels 2 included in the display device 1 may not extend to a part of the non-display area 101 overlapping with other image display panels 2 . Specifically, for example, by making all the image display panels 2 included in the display device 1 of this embodiment the image display panel 2 provided with the polarizing unit 90 in the same arrangement as the image display panel 2b, it is possible to form all the image display panels 2 included in the display device 1. The polarizing portion 90 of the image display panel 2 does not extend to a part of the non-display area 101 overlapping with another image display panel 2 . In this case, it is possible to unify the arrangement of the polarizers 90 of the four image display panels 2 included in the display device 1 . Therefore, it becomes unnecessary to distinguish between the image display panel 2a and the image display panel 2b, so that the work related to the manufacture of the image display panel 2 constituting the display device 1 can be further simplified.

17 is a schematic cross-sectional view showing another example of the connection structure of the image display panel 2 c and the positional relationship between the boundary between the display area 100 and the non-display area 101 and the polarizer 90 . FIG. 17 shows an example of the configuration of the non-display area 101 in which the polarizers 90 of all the image display panels 2c do not extend to overlap with other image display panels 2c. In the example shown in FIG. 17 , when viewed from the display surface side, among the side surfaces of the polarizer 90 of the image display panel 2c, the side surface 106 on the side of the image display panel 2c on the rear side is located between the display area 100 and the display area 100. on the boundary between the non-display areas 101 . In other words, the polarizing portion 90 of the image display panel 2c covers the display area 100, and partly extends to a position other than the non-display area 101 overlapping with other image display panels 2c on the connection of the plurality of image display panels 2c. Non-display area 101.

As shown in FIG. 17, since the polarizing portion 90 does not extend to a part of the non-display area 101 overlapping with other image display panels 2c on the connection of a plurality of image display panels 2c, it is possible to obtain a larger overlap between the image display panels 2c. The size of the overlapping range W6 can be at most equal to the width of one side of the non-display area 101 (any one of the widths W1 to W4). That is, by maximizing the overlapping degree of the non-display regions 101 in the connection of the image display panels 2c, it is possible to make the non-display regions 100 located between the display regions 100 of each of the image display panels 2c when viewed from the display surface side. The width of the display area 101 is the minimum (the width of one side of the non-display area 101 ). In this embodiment, when the degree of repetition is maximized, the side surface of the image display panel 2c on the rear side of the side surface of the image display panel 2c on the display side becomes the side surface of the image display panel 2c on the rear side. on the boundary between the display area 100 and the non-display area 101.

Moreover, as shown in the example of FIG. 15, FIG. 17 etc., the image display panel 2 of this embodiment is provided with the polarizing plate 26A provided in the back side. Such a polarizing plate 26A is, for example, the same polarizing plate 26A as that included in the polarizing unit 90 . Note that the thickness of the polarizing plate 26A shown in FIG. 15 and the like does not represent the actual thickness of the polarizing plate 26A, but is merely a schematic illustration showing the arrangement of the polarizing plate 26A. By providing the polarizing plate 26A on the back side, the degree of expansion and contraction of the polarizing plates 26 and 26A due to changes in environmental conditions such as temperature changes can be made more similar to the display surface side and the back side of the display unit 95 . That is, by approximating the degree of expansion or contraction of the polarizer 26 of the polarizer 90 on the display surface 102 side of the display unit 95 and the degree of expansion or contraction of the polarizer 26A on the back side, the image display panel can be reduced in size. 2 Possibility of bending due to elongation of the polarizing plate 26 or the like.

FIG. 18 is a schematic cross-sectional view illustrating an example of a connection structure of image display panels 2 d and 2 e provided with processed portions 121 and 122 . At least one of the overlapping two image display panels 2d, 2e may have a processed portion (for example, a processed portion) that is processed so that the thickness in the overlapping direction of the abutting position that is abutted by overlapping is thinner than the thickness of other positions. 121, 122). When the processed portion 121 is provided on the image display panel 2d on the display surface side, it is provided on the back side of the image display panel 2d. When the processed portion 122 is provided on the image display panel 2e on the rear side, it is provided on the display surface side of the image display panel 2e.

Specifically, in the case where both of the overlapping two image display panels 2d and 2e have processed portions 121 and 122, for example, as shown in FIG. The lower surface side of the circuit board 14A has an inclined processed portion 121 . In addition, the image display panel 2e on the back side has the processed portion 122 inclined on the top side of the second substrate 23A from the display side to the back side. The range where the processed parts 121 and 122 are provided is a so-called overlapping range (for example, the overlapping range W5 in FIG. 15 , the overlapping range W6 in FIG. 17 , etc.). In the case of the example shown in FIG. 18, when the image display panels 2d, 2e are overlapped, the processed parts 121, 122 are provided so that the display surface 102 of the image display panel 2d is parallel to the display surface 102 of the image display panel 2e. In addition, in FIG. 18 , a gap between the processed portion 121 and the processed portion 122 is illustrated, but such a gap is schematic and not essential. Such a gap may be filled with, for example, an adhesive or the like, or may be filled by the contact of the image display panels 2d and 2e.

At least one of the two overlapping image display panels 2 may have a processed portion. For example, according to the shape of the display surface side of the second substrate 23 not provided with the processed portion, the processed portion may be provided so that the circuit board 14a of the image display panel 2 on the display surface side becomes thinner from the back side to the display surface side. Furthermore, according to the shape of the back side of the circuit board 14a without the processed part, the processed part may be provided so that the second substrate 23 of the image display panel 2 on the rear side becomes thinner from the display surface side to the rear side.

Next, the corner portion of the image display panel 2 to be connected will be described. FIG. 19 is an enlarged view showing a schematic configuration of corner portions connecting the image display panels 2a, 2b near the center of the display area. Among the rectangular image display panels 2a and 2b, the corners that are close to the other image display panels 2a and 2b in the oblique direction intersecting the two directions are cut off. By such cutting, the image display panels 2 a and the image display panels 2 b that are in a positional relationship in the oblique direction can be brought closer to each other.

Specifically, for example, as shown in FIG. 19, the image display panel 2a has a cutout portion 131, which is close to another image display panel 2a in an oblique direction in a rectangular corner portion (see FIG. 12 and FIG. 13) before cutting. A shape with one corner cut off. In addition, the image display panel 2b has a cutout portion 132, which is cut out of a corner portion that is close to the other image display panel 2b in the oblique direction among the rectangular corner portions (see FIG. 12 and FIG. 14 ) before cutting. shape. In the case of the example shown in FIG. 19, since four image display panels 2 (two image display panels 2a and two image display panels 2b) are connected, the cutting of the two image display panels 2a approaching in the oblique direction The portions 131 become parallel to each other. Furthermore, the cut portions 132 of the two image display panels 2b approaching in the oblique direction become parallel to each other. In FIG. 19, there is a gap between two image display panels 2a approaching in the oblique direction and between two image display panels 2b. However, in order to fill the gap, the two image display panels 2a in the oblique direction And the two image display panels 2b may be in contact with each other.

FIG. 20 is an explanatory diagram showing an example of the positional relationship between the boundary line between the display area 100 and the non-display area 101 and the cut portion at the corner. The corner to be cut is a shape cut at least outside of a straight line connecting two points, that is, the rectangular display region 100 and the frame-shaped frame surrounding the display region 100 . Among the borderlines of the non-display area 101, two straight lines (for example, straight lines LA, LB) after extending the two borderlines located closer to the corner are displayed along with the above-mentioned image in contact with the corner. Two points where two straight lines (for example, straight lines LC and LD) intersect in the directions in which the two sides of the panel 2 a trace.

Specifically, as shown in FIG. 20, for example, among the boundary lines between the display area 100 and the non-display area 101, the straight line LA extending the boundary line along the X direction and the line LA close to the other image display panel 2a in the oblique direction The intersection point of the straight line LC along the direction of the side tracing in the Y direction among the two sides that are in contact with one corner portion of , is defined as point P1. In addition, among the boundary lines between the display area 100 and the non-display area 101, the straight line LB extending the boundary line in the Y direction and the two lines contacting a corner close to the other image display panel 2a in the oblique direction The intersection point of the straight line LD along the direction of the side tracing in the X direction among the sides is defined as a point P2. As shown in FIG. 20 , the cutting portion 131 is cut at a position closer to the display region 100 than the straight line LE connecting the point P1 and the point P2 . Thereby, along the two vertical directions (X direction and Y direction), the distance between the display regions 100 can be made closer.

In particular, by making the arrangement of the polarizers 90 of the image display panel 2b the same as that of the two image display panels 2c in FIG. The distance is equal to the width of one side of the non-display area 101 . For example, along the vertical direction shown in FIG. 1 , the distance between the display regions 100 of the two image display panels 2 a and 2 b can be equal to the width W2 (see FIG. 12 ).

In the present embodiment, the cutting amount (XA, YA) of the corner cutting portion 131 cut along a straight line approximately parallel to the straight line LE is larger than the cutting amount (XB, YB ) when cutting on the straight line LE after connecting the point P1 and the point P2 ) is larger, but the cutting amount of the cutting portion 131 may be greater than or equal to the cutting amount when the straight line LE that connects P1 and point P2 is cut.

In addition, in the description referring to FIG. 20 , the cutting portion 131 of the image display panel 2 a was taken as an example, but the same applies to the cutting portion 132 of the image display panel 2 b and the cutting portion 133 described later. In addition, other image display panels (for example, image display panels 2c, 2d, 2e, 2a ₁ to 2a ₉ , 2b ₁ to 2b ₉ , etc.) constituting the display device 1 may also have their corners cut off.

The shapes of the cutouts 131 to 133 viewed from the display surface side are not limited to those that draw a straight line. Some or all of the cutting parts 131 to 133 may have a curved shape such as a circle.

Next, the configuration provided on the display surface side of the display device 1 will be described. The display device 1 includes a transparent cover portion 140 that covers at least a part of the display surface side connected to the display region so that the display surface of the display region becomes planar.

FIG. 21 , FIG. 22 and FIG. 23 are diagrams showing an example of the configuration of the cover portion 140 . FIG. 24 and FIG. 25 are diagrams showing an example of a configuration having a film 143 . As shown in FIG. 21 , FIG. 22 and FIG. 25 , the cover unit 140 may have a cover member 141 covering all the display surface sides of the connected plurality of image display panels 2 a and 2 b. Specifically, the cover member 141 is, for example, a member that is flat at least on the display surface side, and is mainly made of resin such as plastic. As shown in FIGS. 21 , 22 , and 25 , by providing the plate-shaped cover member 141 , the display surface side of the display device 1 connected to the display region can be flattened with a simple configuration. Thereby, it is easy to align the traveling direction (reflection direction, scattering direction, etc.) of light on the display surface side over the entire connection display area.

As shown in FIG. 23, the shape of the cover member 141a on the side of the image display panels 2a, 2b may correspond to the height difference between the polarizers 90 of the plurality of image display panels 2a, 2b generated by overlapping the non-display areas 101. height shape. Thereby, the gap between the cover member 141a and the image display panel 2b located farther than the cover member 141a can be made smaller. Furthermore, by arranging the plurality of image display panels 2a, 2b according to the height difference of the cover member 141a, it is easy to recognize the positional relationship (the relationship between the display surface side and the rear side, etc.) of the plurality of image display panels 2a, 2b.

As shown in FIGS. 22 , 23 and 25 , the cover portion 140 may have a filler 142 filled between the cover members 141 , 141 a and the image display panels 2 a , 2 b. The filler 142 is, for example, a transparent resin that is viscous when filled, and is cured by being irradiated with ultraviolet rays or the like. Filling the filler 142 between the cover members 141 , 141 a and the image display panels 2 a , 2 b makes it easier to make the direction of light passing through the cover members 141 , 141 a more uniform.

Furthermore, as shown in FIGS. 24 and 25 , the display device 1 may have a film 143 positioned on the display surface side of the polarizer 90 of the image display panel 2 b provided on the rear side. In this case, the thickness of the film 143 corresponds to the height difference between the polarizer 90 provided on the image display panel 2b on the rear side and the polarizer 90 provided on the image display panel 2a on the display surface side. Specifically, for example, as shown in FIGS. 24 and 25 , a film 143 may be stretched on the display surface side of the polarizer 90 of the image display panel 2 b on the rear side. In this case, the height of the display surface side of the film 143 based on the display surface 102 of the image display panel 2b is the same as the height of the polarizer 90 provided on the image display panel 2a overlapping with the image display panel 2b. high. The film 143 is, for example, a film-shaped member mainly made of resin such as polyethylene terephthalate (PET). Thereby, the height difference of the display surface side of the several connected image display panel 2a, 2b can be alleviated further.

In addition, as shown in FIGS. 24 and 25 , a film 143 may be provided on the back side of the image display panel 2 a on the display side. Thereby, the difference in height on the back side can be further alleviated.

Above, the lid portion 140 has been described by taking the structure connecting the image display panels 2a, 2b as an example, but the lid portion 140 can also be provided on other image display panels (for example, the image display panels 2c, 2d, 2e, 2a ₁ to 2a ₉ , 2b ₁ to 2b ₉ , etc.) on the display device 1 constituted.

Next, the angle of the image display panel 2 when the display device 1 is installed will be described. FIG. 26 is a schematic diagram showing an example of the installation angle of the panel based on the incident direction of light from the light source LI and the viewer HU. The angle of the image display panel 2 is preferably determined based on the incident direction of light from the light source LI of the image display panel 2 and the positional relationship between the display device 1 and the viewer HU who recognizes the image displayed in the connection display area. Specifically, it is preferable that the angle is such that the image display panel 2 can more favorably guide the light from the light source LI to the viewer HU. This angle is, for example, an angle at which light from the light source LI is guided to the viewer HU, assuming specular reflection.

FIG. 27 is a diagram showing a comparative example in which only the non-display regions 101 of the image display panels provided with the polarizing units 90 overlap each other. When the existing image display panels are overlapped so that parts of the non-display regions 101 overlap each other, as shown in FIG. 95 and the display portion 95 on the back side within the overlapping range W7. That is, the polarizer 90 provided on the rear image display panel increases the height difference between the display surface side of the display surface side image display panel and the display surface side of the rear image display panel. Since the larger the height difference is, the easier it is to recognize, therefore, it is difficult to reduce the possibility of recognizing the height difference with the conventional configuration.

On the other hand, according to the present embodiment, among the side parts of the polarizer 90 of the image display panel 2b on the rear side, the side part (side part 105) on the side of the image display panel 2a on the display side side, and the side part 105 of the image display panel on the display side side Among the side parts of 2a, the side part (side part 106) on the side of the image display panel 2b located on the rear side faces. That is, the image display panel 2 b on the rear side does not extend to a position where the polarizing portion 90 overlaps the image display panel 2 a on the display surface side. Therefore, along the overlapping direction of the two image display panels 2a and 2b in which a part of the non-display area 101 overlaps each other, two images can be superimposed without increasing the thickness of the polarizer 90 of the image display panel 2b on the rear side. Display panels 2a, 2b. Therefore, the height difference between the display surface 102 of the image display panel 2 a on the display surface side and the display surface 102 of the image display panel 2 b on the rear side can be made smaller. Therefore, even if the configuration including the polarizing plate 26 is provided on the display surface 102 , it is possible to make the level difference generated between the plurality of display regions 100 more difficult to see.

Furthermore, by forming the non-display region 101 in which the polarizers 90 of all the image display panels 2 (for example, the image display panel 2c) included in the display device 1 do not extend to positions overlapping with other image display panels 2, the display devices are unified. It is possible to arrange the polarizers 90 of all the image display panels 2 included in the image display panel 1. Therefore, there is no need to distinguish between the image display panel 2 a on the display surface side and the image display panel 2 b on the back side, and the work related to the manufacture of the image display panel 2 constituting the display device 1 can be simplified.

Furthermore, by extending the polarizing portion 90 of the image display panel 2a on the display surface side to the non-display region 101 at a position overlapping with the image display panel 2b on the rear side, it becomes easy to widen the polarizing portion 90 of the image display panel 2a on the display surface side. The accuracy required for the adjustment of the positional relationship with the display area 100 can be made easier to manufacture the image display panel 2 a on the display surface side.

Furthermore, by bringing the image display panel 2a on the display surface side and the image display panel 2b on the rear side into contact, the height difference between the display portion 95 on the display surface side and the display portion 95 on the rear side can be further reduced.

Moreover, since at least one of the two image display panels 2 (for example, image display panels 2d, 2e) has a processed portion (for example, processed portions 121, 122, etc.), the size of the image display panel 2d on the display surface side can be further reduced. The height difference between the display surface side and the display surface side of the image display panel 2e on the back side.

Moreover, by locating the side surface portion 106 of the image display panel 2c on the display surface side on the boundary between the display area 100 and the non-display area 101 of the image display panel 2c on the rear side, when viewed from the display surface side, further reduction can be achieved. The width of the non-display area 101 located between the display areas 100 of each of the image display panels 2c is reduced so that it becomes more difficult to recognize the non-display area 101 located in the connected display area.

Furthermore, since the angle of the image display panel 2 is an angle determined based on the incident direction of light from the light source LI of the image display panel 2 and the positional relationship between the display device 1 and the viewer HU who recognizes the image displayed in the connection display area, , the image display panel 2 can better guide the light from the light source LI to the viewer HU.

And, along the two directions perpendicular to each other of four rectangular image display panels 2 (for example, image display panels 2a, 2b), on the display device 1 having two connected display areas, by making the image display panels Among the corners, the corners that are close to other image display panels 2 in the oblique direction intersecting the two directions are cut off, so that the image display panels 2 that are in a positional relationship in the oblique direction can be brought closer to each other.

Furthermore, since the cut corner is a shape that is cut outside the straight line connecting the two points, that is, the rectangular display area 100 and the frame-shaped non-display area surrounding the display area 100 Among the boundary lines of the region 101, the two straight lines LA and LB extended from the two boundary lines located closer to the corner, and the two straight lines tracing the direction of the two sides of the image display panel 2 in contact with the corner. Since there are two points at which straight lines LC and LD intersect, the distances between the display regions 100 can be made closer in two perpendicular directions.

Furthermore, the positions in the overlapping direction of a pair of image display panels 2 approaching in an oblique direction intersecting the two directions with respect to the other pair of image display panels 2 approaching in an oblique direction are either on the display surface side or on the rear surface. side. Accordingly, the thickness of the display portion 95 in the overall thickness of the display device 1 can be suppressed to the thickness of the display portions 95 of the two image display panels 2 . In addition, in the direction along the display surface 102 , it becomes easy to achieve a balance related to various design matters such as the weight of the display device 1 , the height difference shape, and the like.

Furthermore, by providing the cover portion 140 , the display surface side connected to the display region can be flattened. Therefore, it is easy to align the traveling direction (reflection direction, scattering direction, etc.) of light on the display surface side over the entire connection display area.

Furthermore, by providing the cover part 140 with the cover members 141 and 141a, the display surface side connected to the display area of the display device 1 can be flattened with a simple configuration.

Furthermore, since the shape of the image display panel 2 (for example, image display panels 2a, 2b) side of the cover member 141a is a height shape corresponding to the height difference between the polarizers 90 of a plurality of image display panels 2, it is possible to further reduce the A gap between the small cover member 141a and the image display panel 2 located farther than the cover member 141a. Furthermore, by arranging the plurality of image display panels 2 according to the height difference of the cover member 141a, the positional relationship of the plurality of image display panels 2 (the relationship between the display surface side and the rear side, etc.) becomes easy to recognize. Therefore, it is possible to guide the operations related to the connection of the image display panel 2 in the manufacture of the display device 1 using the cover member 141 a.

Furthermore, by filling filler 142 between cover members 141, 141a and image display panel 2 (for example, image display panels 2a, 2b), the traveling direction of light passing through cover members 141, 141a can be made more consistent.

Furthermore, by using the film 143 , it is possible to further relax the height difference on the display surface side of the connected image display panel 2 (for example, the image display panels 2 a , 2 b ).

Furthermore, by providing the polarizing plate 26A provided on the back side, the degrees of expansion and contraction of the polarizing plates 26 and 26A can be made more similar on the display surface side and the back side of the display unit 95, thereby reducing the burden on the image display panel 2 due to the polarizing plate 26. Possibility of bending due to elongation.

Furthermore, since the image display panel 2 is a reflective liquid crystal display panel, components constituting a backlight can be omitted. Therefore, it is easy to make the thickness of the display device 1 thinner.

In other words, the image display panel 2b ₃ is located on the display surface side of the image display panel 2b ₂ . Also, the image display panel _2b2 is located _on the display surface side of the image display panel 2b1. Also, the relative positional relationship of the overlapping states of the three image display panels 2a ₁ , 2a ₂ , and 2a ₃ is the same as the relative positional relationship of the overlapping states of the three image display panels 2b ₁ , 2b ₂ , and 2b ₃ . In this way, in Modification 1, the relative positional relationship of the overlapping state of the image display panels 2 arranged on one end side of the plurality of image display panels 2 connected in the Y direction is the same. In Modification 1, since the positional relationship is the same along the overlapping direction, the fourth and subsequent image display panels 2 may be provided along the Y direction. Specifically, the image display panel 2 positioned on the display surface side of the image display panels 2a ₃ and 2b ₃ may be provided at the other end along the Y direction. For the fifth and subsequent ones, it may be provided so that the other end side of the added fourth and subsequent ones is located on the display surface side.

The position in the overlapping direction of the side-connected image display panels 2 is H ₃ . Moreover, the positions in the overlapping direction of the image display panels _{2b 2} and 2a ₂ arranged in the X direction are H ₂ and H ₃ , _respectively . The position in the overlapping direction of the image display panel 2 is H ₄ . Moreover, the positions in the overlapping direction _of the image display panels 2b ₃ and _{2a 3} arranged in the X direction are H ₃ and H ₄ , respectively. The position in the overlapping direction of the image display panel ₂ is closer to the display surface side than H4.

FIG. 33 shows the positional relationship seen from the direction of arrow V3. In addition, in FIGS. 32 and 33 , H _a , H _b , H _c , and H _d represent positions in the overlapping direction, and the H _d side is the display side, and the H _a side is the back side. The display device according to Modification 4 has, for example, a 2×3 pattern along two directions intersected by six rectangular image display panels, ie, image display panels 2a ₇ , 2a ₈ , 2a ₉ , 2b ₇ , 2b ₈ , and 2b ₉ . Configure the connection display area for the connection. The connection direction of the image display panel 2 in Modification 4, that is, the two intersecting directions are not necessarily perpendicular to each other, as in the two directions of Modifications 2 and 3.

Furthermore, in Modification 4, part of the wiring portion 110 of the image display panel 2 on the rear side is connected through the image display panel 2 on the display surface side so as to be a position hidden from the display surface side along the Y direction. Furthermore, in Modification 4, the adjacent image display panels 2 in the X direction are in directions in which the wiring portions 110 extend in opposite directions. Assuming that in Modification 4, when the third and subsequent image display panels 2 are installed along the X direction, the image display panels 2 located at the (2n-1)th position counted from one end side and the image display panel 2 located at the 2nth position Among the panels 2, the wiring portions 110 extend in the same direction, and the wiring portions 110 of the image display panel 2 at the (2n-1)th position and the image display panel 2 at the 2nth position extend in opposite directions.

In the example shown in FIG. 32 , the image display panel 2b to ₇ disposed on one end side in the Y direction (the upper end side in FIG. 32 ) is positioned at the image display panel 2a disposed on the other end side (the center portion in the vertical direction in FIG. 32 ). ₈ on the back side. Furthermore, the image display panel _2a8 is located _on the back side of the image display panel 2a9 arranged on the other end side (the lower end side in FIG. 32). Furthermore, the image display panels 2a to ₇ arranged on one end side in the Y direction are located on the display surface side of the image display panels 2b to ₈ arranged on the other end side. Furthermore, the image display panel 2b ₈ is located on the display surface side of the image display panel 2b ₉ arranged on the other end side (the lower end side in FIG. 32 ). In this way, in Modification 4, the column pairs of image display panels constituting a plurality of image display panels 2 connected along one of the two directions are arranged on one end side of one direction in each column. The relative positional relationship of the overlapped state is the same. In Modification 4, the fourth and subsequent image display panels 2 can be arranged in the same direction as in Modifications 1 and 3 in the same direction.

In each of the columns of image display panels, the plurality of image display panels 2 having the above-mentioned relative positional relationship in an overlapping state have different directions in other directions that are different from the direction of the column of the image display panels. Non-butting relationships that must directly overlap. Specifically, the image display panel _2a7 and the image display panel 2b7 overlap in a positional relationship with the image display panel _{2a7 on} the display side and the image display panel 2b7 _on the back side. In addition, the image display panel _2a8 and the image display panel _2b8 overlap in a positional relationship with the image display panel 2a8 _on the display side and the image display panel 2b8 _on the back side. On the other hand, the image display panels 2a to ₉ only overlap the adjacent image display panels 2a to ₈ in the Y direction, and do not directly overlap the adjacent image display panels 2b to ₉ in the X direction. As a specific example, the positions in the overlapping direction of the image display panels 2b ₇ , 2a ₇ , 2b ₈ , 2a ₈ , 2b ₉ , and 2a ₉ arranged in the X direction are H _a , H _b , H _b , H _c , _Hc , _Hd . However, the superimposed portion of the image display panels 2a to 2b _{on the appearance of the image display panels 2b and 9 viewed} from the display surface side is the overlapping range of the two image display panels 2 directly overlapping along the X direction (for example, refer to the overlapping The range W5 or overlapping range W6) is the same.
