And liquid crystal sealed in a region surrounded by the seal portion 3. Here, in a state where the first substrate 1 and the second substrate 2 are bonded to face each other, the first substrate 1 projects from the edge of the second substrate 2 (hereinafter referred to as “projected region C”). The second substrate 2 has a region protruding from the edge of the first substrate 1 (hereinafter referred to as “projected region D”). A plurality of data electrodes (data electrodes) 11 are formed on the inner side (liquid crystal 4 side) of the first substrate 1, and each data electrode 11 reaches the overhanging region C of the first substrate 1 and enters the region. The data electrode drive circuit 5 is connected to an output terminal of the data electrode drive circuit 5 provided. On the other hand, a plurality of scanning electrodes 21 are formed inside the second substrate 2 (on the liquid crystal side) so as to be orthogonal to each of the plurality of data electrodes 11.

With such a configuration, an output signal from the data electrode drive circuit 5 is supplied to each data electrode 11, and an output signal from the scan electrode drive circuit 6 is supplied to each scan electrode 21.

  However, in the case of the above configuration, there is a problem that the space occupied by the liquid crystal panel becomes large because each substrate has a region protruding from the other substrate.

Each of the data electrodes 11 formed on the first substrate 1 is electrically connected to each output terminal of the liquid crystal driving circuit 7 on the second substrate 2 through a conductive material mixed in the sealing material 3. It has become.

  Incidentally, in recent years, with the demand for larger size and higher resolution of the liquid crystal panel, the number of electrodes formed on each substrate of the liquid crystal panel has increased. For this reason, it is necessary to form a very large number of electrodes so as to reach one liquid crystal driving circuit without short-circuiting each other, and it is extremely difficult to form the electrodes.

The present invention has been made in view of the circumstances described above, and even when there are many electrodes to be formed on each substrate, the electrodes occupy relatively easily without increasing the space occupied by the liquid crystal panel. An object of the present invention is to provide a liquid crystal display device capable of forming the above and an electronic apparatus using the same.

  The present invention provides an electronic apparatus comprising the liquid crystal display device of the present invention as a display unit. According to such an electronic device, the size of the liquid crystal display device as a display unit can be reduced, and thus the electronic device itself can be reduced in size. Furthermore, the electrodes of the liquid crystal display device can be easily formed.

  Embodiments of the present invention will be described below with reference to the drawings. Such an embodiment shows one aspect of the present invention, and does not limit the present invention, and can be arbitrarily changed within the scope of the present invention.

A: Configuration of Embodiment FIG. 1 is a perspective view showing a configuration of a liquid crystal panel 100 according to an embodiment of the present invention, and FIG. 2 is an exploded perspective view of the liquid crystal panel 100. In these drawings and the following drawings, the scales are different for each layer and each member so that each layer and each member can be recognized on the drawing.

  As shown in FIGS. 1 and 2, the liquid crystal panel 100 includes a first substrate 1 and a second substrate 2 that are arranged to face each other, and a rectangular frame-shaped seal portion 3 that is interposed between the two substrates. And a liquid crystal 4 sealed in a region surrounded by the first substrate 1, the second substrate 2, and the seal portion 3.

Is formed. Specifically, a plurality of first data electrodes 11 are formed in a stripe shape on the inner surface of the first substrate 1. Meanwhile, the first substrate 1 and the second substrate 2 are bonded to the inner surface of the second substrate 2 with the plurality of scanning electrodes 21 having portions orthogonal to the first data electrodes 11. A plurality of second data electrodes 22 electrically connected to the data electrode 11 are formed. Each of the first data electrode 11, the scanning electrode 21, and the second data electrode 22 is a transparent electrode formed of, for example, ITO (Indium Tin Oxide) or the like. In the present embodiment, the number of first data electrodes 11 is larger than the number of scanning electrodes 21. Each of the second data electrodes 22 corresponds to each of the first data electrodes 11 and is provided in the same number as the number of the first data electrodes 11.

  Here, as shown in FIGS. 1 and 2, the second substrate 2 is larger (longer) in one direction than the first substrate 1. Therefore, a part of the second substrate 2 projects from one edge (the edge indicated by A in FIG. 2) of the first substrate 1 in a state where the two substrates are bonded together. A voltage corresponding to an image signal is supplied to the plurality of first data electrodes 11 in the vicinity of the central portion in the X-axis direction in the drawing of this overhanging region (hereinafter referred to as “overhanging region 2a”). A data electrode drive circuit 5 is provided for the plurality of scanning electrodes 21 in the vicinity of the end of the overhang region 2a (the end in the negative direction of the X axis in FIG. 2). A scan electrode driving circuit 6 for supplying a voltage corresponding to the above is provided. Further, a terminal portion 8 connected to the input terminals of the data electrode driving circuit 5 and the scanning electrode driving circuit 6 is formed on the overhanging region 2a, and an image signal output from an external device is supplied to this terminal. It is supplied to each drive circuit via the unit 8.

  The surface of the first substrate 1 on which the plurality of first data electrodes 11 are formed and the surface of the second substrate 2 on which the plurality of scan electrodes 21 are formed are covered with an alignment film (not shown). This alignment film is obtained by subjecting an organic thin film such as polyimide to a uniaxial alignment process, for example, a rubbing process. The liquid crystal sealed between the two substrates is aligned according to the rubbing direction of the alignment film in a state where no electric field is applied. On the other hand, polarizing plates (not shown) are respectively attached to the outer surfaces of the first substrate 1 and the second substrate 2, and each polarizing plate corresponds to the alignment direction of the alignment film covering the inner surface of each substrate. The polarization axis is set.

  The seal portion 3 is made of a thermosetting epoxy resin or the like, and is mixed with a spacer material for keeping the gap between the first substrate 1 and the second substrate 2 at a constant thickness. The seal portion 3 has an opening 3a for injecting the liquid crystal 4 in part. The opening 3 a is closed by an adhesive after the liquid crystal 4 is injected into a region surrounded by the first substrate 1, the second substrate 2, and the seal portion 3.

  In addition to the spacer material, conductive particles are mixed in the seal portion 3. The conductive particles are obtained by plating the surface of elastically deformable plastic beads. Although details will be described later, the first data electrodes 11 formed on the first substrate 1 and the second data electrodes 22 formed on the second substrate 2 are electrically connected by the conductive particles.

  Next, with reference to FIG. 3 and FIG. 4, the detailed structure of each electrode formed on the 1st board | substrate 1 and the 2nd board | substrate 2 is demonstrated. In the following, a region of the second substrate 2 other than the overhanging region 2a, that is, a region facing the first substrate 1 is referred to as “opposing region 2b”.

  First, FIG. 3 is a plan view showing a detailed configuration of the surface of the first substrate 1 on the liquid crystal 4 side. As shown in the figure, a plurality of first data electrodes 11 are formed on the surface of the first substrate 1 on the liquid crystal 4 side. Each of the first data electrodes 11 is formed in a direction parallel to the Y axis in the vicinity of the display electrode 11a formed in a direction parallel to the Y axis in the drawing and the edge A of the first substrate 1. It is comprised by the terminal 11c for conduction | electrical_connection, and the extraction electrode 11b formed in the shape which connects each display electrode 11a and the terminal 11c for conduction | electrical_connection. Here, the width of each conduction terminal 11c is narrower than the width of each display electrode 11a. That is, when viewed as a whole, the plurality of first data electrodes 11 have a shape that converges toward the center of the edge A in the vicinity of the edge A of the first substrate 1.

  On the other hand, FIG. 4 is a plan view showing a detailed configuration of the surface of the second substrate 2 on the liquid crystal 4 side. As described above, the plurality of second data electrodes 22 and the plurality of scanning electrodes 21 are formed on the surface of the second substrate 2 on the liquid crystal 4 side. As shown in FIG. 4, each second data electrode 22 includes a conduction terminal 22a, a first input terminal 22c, and a conduction terminal 22a formed in a portion of the opposing region 2b near the overhanging region 2a. And an extraction electrode 22b formed in a shape connecting the first input terminals 22c. The first input terminals 22c of the second data electrodes 22 are arranged in the X-axis direction in the vicinity of the central portion in the X-axis direction of the overhang region 2a.

  On the other hand, each of the plurality of scanning electrodes 21 formed on the second substrate 2 includes a display electrode 21a formed extending in a direction parallel to the X axis, and the vicinity of the end of the overhang region 2a (see FIG. 4 includes a second input terminal 21c formed in the vicinity of the left end), and an extraction electrode 21b formed in a shape connecting one end of each display electrode 21a and each second input terminal 21c. . That is, each extraction electrode 21b is formed in a shape extending from one end of the display electrode 21a located in the negative direction of the X axis along one side of the second substrate 2 to one end of the second input terminal 21c. . Further, the second input terminals 21c of the scanning electrodes 21 are arranged in the X-axis direction in the vicinity of the end of the overhang region 2a.

  Next, FIG. 5 shows a structure in which the first substrate 1 and the second substrate 2 are bonded to each other with the seal portion 3 sandwiched so that the electrodes formed on the respective surfaces face each other. It is a top view which shows the detailed structure at the time of seeing from the side. As can be seen from FIG. 5 and FIG. 3 and FIG. 4, the conductive terminals 11c of the first data electrodes 11 formed on the first substrate 1 and the second substrate in a state where the two substrates are bonded together. 2 is opposed to the conduction terminal 22 a of each second data electrode 22 formed on the 2 via the seal material 3. The conduction terminals 11c and 22a are made conductive by the conductive particles mixed in the sealing material 3. As a result, each first data electrode 11 and the second data electrode 22 are electrically connected to form one data electrode, and a plurality of data electrodes occupying most of the first substrate 1 as a whole, The shape reaches the vicinity of the center of the overhang region 2a of the second substrate 2 while converging.

  Here, FIG. 6 shows each conduction terminal 11 c formed on the first substrate 1 and each conduction terminal 22 a formed on the second substrate 2, and the seal portion 3 (conductivity between them). It is sectional drawing which expands and shows the part of the vicinity of the active particle 3b is included. As shown in the figure, when the first substrate 1 and the second substrate 2 are bonded together, a force that narrows the gap in a state where the conductive terminal 11c and the corresponding conductive terminal 22a face each other. When the seal part 3 is cured while adding the conductive particles 3 b, the conductive particles 3 b in the seal part 3 are crushed between the first substrate 1 and the second substrate 2. As a result, the conductive particles 3b positioned between each conduction terminal 11c and the conduction terminal 22a opposite thereto conduct the conduction terminal 11c and the conduction terminal 22a. On the other hand, since the conductive particles 3b located in a region other than the region where the conduction terminal 11c and the conduction terminal 22a face each other are not involved in the conduction of each part, the conduction terminals 11c and the conduction particles opposite thereto are connected. Only the terminal 22a is electrically connected.

  In FIG. 5 again, the first input terminal 22 c serving as one end of each data electrode is connected to each output terminal of the data electrode driving circuit 5 disposed in the vicinity of the central portion of the overhang region 2 a of the second substrate 2. . Each output terminal of the data electrode drive circuit 5 and each of the first input terminals 22c are connected through, for example, an ACF (Anisotropic Conductive Film) or the like.

  On the other hand, the second input terminal 21 c of each scanning electrode 21 formed on the second substrate 2 is each output terminal of the scanning electrode driving circuit 6 disposed in the vicinity of the end of the overhanging region 2 a of the second substrate 2. Connected to. These units are also connected via the ACF described above.

  In the state where the first substrate 1 and the second substrate 2 are bonded together, the display electrode 11a of each first data electrode 11 and the display electrode 21a of each scan electrode 21 are orthogonal to each other. A pixel is formed by a portion where the display electrodes 11a and 21a intersect and the liquid crystal 4 sandwiched between the portions. That is, an image is displayed in a region where the display electrodes 11a and 21a intersect. Hereinafter, this area is referred to as an image display area. In the present embodiment, each of the first data electrode 11 and the scanning electrode 21 is formed so as to reach a region other than the image display region described above (that is, a peripheral portion of the image display region). For example, it is an electrode formed in a portion surrounded by a broken line in FIGS. The electrodes formed in these areas have no role in displaying images, but have the role of making the gap thickness between the two substrates substantially the same in the image display area and other areas. Yes. In other words, tentatively, the first data electrode 11 and the scan electrode 21 are formed only in the image display region in the region surrounded by the seal portion 3 (the region in which the liquid crystal 4 is sealed), and the electrode is formed in the other region. If the gap is not formed, the thickness of the gap between the two substrates in the area other than the image display area becomes thicker by the thickness of the electrode than the thickness of the gap between the two boards in the image display area. That is, there is a problem that the thickness of the liquid crystal layer in a region other than the image display region is different from the thickness of the liquid crystal layer in the image display region, and as a result, the color of each region is different. On the other hand, in the present embodiment, such an inconvenience does not occur because the electrodes are also formed in portions other than the image display area. Hereinafter, the electrode formed in the region other than the image display region is referred to as a “dummy electrode”. In the present embodiment, a dummy electrode (indicated by B in FIG. 4) is also formed on the region on the second substrate 2 located between the extraction electrode 11b of the first data electrode 11 and the extraction electrode 21b of the scanning electrode 21. Part) is formed.

  The above is the configuration of the liquid crystal panel 100 according to the present embodiment.

  As described above, according to the present embodiment, since both the data electrode drive circuit 5 and the scan electrode drive circuit 6 are disposed on the overhanging region 2a of the second substrate 2, as shown in FIG. Compared to the conventional technique, there is an advantage that the size of the liquid crystal panel can be reduced. In addition, since the drive circuit connected to the data electrode and the drive circuit connected to the scan electrode are provided separately, the electrodes are formed compared to the case where each electrode is formed to reach one drive circuit. It can be done easily.

  In the present embodiment, the data electrodes are converged near the center of the overhanging region 2a and connected to the output terminal of the data electrode driving circuit 5 that is also arranged near the center of the overhanging region 2a. It has become. Here, when one electrode is converged in the vicinity of the central portion of the overhang region 2a, the following advantages are obtained.

  First, assuming that each data electrode is converged toward the vicinity of the right end (X-axis positive direction side) of the overhang region 2a, the extending direction of the extraction electrode 22b of the second data electrode 22 and the negative direction of the X-axis 5 is smaller than the case shown in FIG. 5 and the width of the extraction electrode 22b of the second data electrode 22 is shown in FIG. Must be narrower than. When the width of the electrode is narrowed, there is a problem that disconnection of each electrode, short circuit between adjacent electrodes, etc. are likely to occur. On the other hand, in the present embodiment, since the data electrode is converged near the central portion of the overhang region 2a, the angle α is not so small. Therefore, the width of the extraction electrode 22b of the second data electrode 22 is not as narrow as when each data electrode is converged to the end of the overhanging region 2a, so that the above-described problem can be avoided.

  In the present embodiment, when the data electrode and the scanning electrode 21 having the larger number of wires are converged near the center of the overhang region 2a, the following advantages are obtained. That is, if the electrode with the smaller number is formed so as to converge near the center of the overhang region 2a, it is necessary to form the electrode with the larger number so as to avoid the region where the electrode is formed. is there. On the other hand, when the electrode with the larger number is converged near the center, the electrode is preferentially formed on the substrate, and the electrode with the smaller number is formed so as to avoid the region where the electrode is formed. Therefore, restrictions on electrode formation can be reduced as compared with the case described above.

  In the present embodiment, the data electrode converged on the central portion of the overhanging region 2 a is formed by being divided into the first substrate 1 and the second substrate 2 and is made conductive by the conductive particles in the seal portion 3. The configuration. As described above, when the electrodes converged on the central portion of the overhang region are made conductive between the substrates, there are the following advantages. That is, as described above, when the electrode having the larger number is converged near the center of the overhang region 2a, the electrode can be formed preferentially in comparison with the electrode having the smaller number. it can. Therefore, the shape of the conduction terminal 11c of the first data electrode 11 and the conduction terminal 22a of the second data electrode 22 (such as the width and interval of each of the conduction terminals 11c and 22a) are reliably conducted via the conductive material. It is possible to obtain a shape necessary and sufficient for the purpose.

  In the above embodiment, the liquid crystal panel having the number of data electrodes larger than the number of scan electrodes has been described as an example. However, the present invention is also applied to a liquid crystal panel having a number of scan electrodes larger than the number of data electrodes. Can be applied. In this case, the large number of scanning electrodes are converged on the center of the overhanging region of the second substrate, and the end of each scanning electrode is connected to the output terminal of the scanning line driving circuit disposed near the center of the region. What is necessary is just to make it connect.
