200919055 VI. Description of the Invention: [Technical Field] The present invention relates to a liquid crystal display device and an electronic device, which have less crosstalk, good display quality, and wide viewing angle. [Prior Art] A liquid crystal display device includes a pair of transparent substrates on which electrodes are formed on the surface, and a liquid crystal layer sandwiched between the pair of substrates, which are often used to rearrange liquid crystals by applying voltages to electrodes on the two substrates. A vertical electric field method that displays various kinds of information. The liquid crystal display device of the vertical electric field type as described above is generally a TN (Twisted Nematic) mode, but due to the problem of narrow viewing angle, VA (Vertical) has been developed.

Alignment ’ vertical alignment mode, MVA (Multidomain Vertical)

Various modified vertical electric field type liquid crystal display devices such as Alignment 'multi-quadrant vertical alignment mode'. In the other direction, unlike the above-described vertical electric field type liquid crystal display device, there is also an IPS (In-Plane Switching) mode and FFS (Fringe Field Switching) in which only one of the substrates has a counter electrode composed of a pixel electrode and a common electrode. , edge electric field effect) mode liquid crystal display device. Among them, in the IPS mode liquid crystal display device, the counter electrode is disposed in the same layer, and the direction of the electric field applied to the liquid crystal is rearranged in a direction parallel to the substrate in a direction substantially parallel to the substrate. Since the IPS mode liquid crystal display device is also referred to as a lateral electric field mode liquid crystal display device, it has a very wide viewing angle compared with the above-described vertical electric field mode liquid crystal display device. However, by setting a pair of electrodes in the same sb-type liquid crystal display, the liquid crystal of the numerator cannot be divided into _ upper side, in order to solve the problem that the transmittance is lowered as described above. Point, developed a problem known as the iPS mode liquid crystal display device.

On the other hand, in the liquid crystal display device of the FFS mode, since the height difference is formed on the surface of the r-square, the planarization film used in the liquid crystal display device of the above-described aspect and A mode is used. The pixel electrode and the co-energization can be disposed on the planarization film - Patent Document 3). [Patent Document 1] Japanese Laid-Open Patent Publication No. 2001-225230 [Patent Document 2] Japanese Laid-Open Patent Publication No. 2002-182230 (Patent Document 3) Japanese Patent Application Laid-Open No. Hei. 5 200919055 (Problems to be Solved by the Invention) In the case of a flat electrode and a common electrode, the upper electrode of the insulating film (hereinafter referred to as "upper electrode") and the lower electrode can be used. (hereinafter referred to as "lower electrode") is used as a common electrode. However, when the lower electrode is used as the pixel electrode, the lower electrode can be extended to the vicinity of the signal line and the scanning line of the switching element, the thin film transistor (4), and thus the opening portion becomes large. The advantage of displaying a bright liquid crystal display panel is obtained. Further, although the upper electrode needs to form a plurality of slits in the pixel region, since the upper electrode can be formed into a sheet shape, the electric resistance of the upper electrode as the common electrode can be made small, and the potential of the common electrode can be stabilized. A good quality FFS mode liquid crystal display device is displayed.

On the other hand, when the upper electrode is used as a common electrode, there is a difference in height in order to form a gap, and an image sticking phenomenon in which a height difference is read is also found. In order to suppress the phenomenon of the afterimage, the height difference of the electrode is very effective. Material, can be tested ^ _ thickness is reduced to about one-half of the thickness of the lower electrode (specifically, 50niJ is formed by conductive materials such as IT◦, (10), so if the thickness of the upper electrode is thinned, the upper electrode will be caused. The resistance value becomes higher. Since the resistance value of the upper electrode formed in each pixel region is higher than that in the case where the upper electrode is formed into a sheet shape, if the resistance value of the electrode is increased, the ride is applied briefly. Electrically degraded, resulting in crosstalk caused by a string or a suitable layer giving a predetermined driving potential. This crosstalk (crosstaIk) is especially noticeable in a display device called a wide-sized birch long liquid crystal 320557 6 200919055 display device.

The electric resistance of the small electric line of the electric circuit is small in appearance, and the first electrode is connected. Therefore, since the second electrode potential of the second electric power is stabilized, it can be applied via the common line, and I: liquid crystal display device can be used. The second electrode. At this time, the retort> electrical material has different compositions as the first electrode and the first electrode 蛊筮q. In addition, the /, the second electrode may be the same composition or may be P- For a switching element in which an Si (polycrystalline stone) type ^ electrode is connected,

(Application Example 2) In the liquid crystal display device of the above-described application example, it is preferable that the low-resistance circuit is formed between the front display region and the common line. According to this configuration, even if the area of the second electrode is not formed as necessary (see, for example, "outside the common line"), the second electrode can be made to have a lower period. , ^ connected. In addition, when there is space between the display area and the common line, J is: a portion of the space forms a low resistance circuit. Therefore, / in order to form a low-resistance circuit, the scratch can be effectively utilized. The area of the area of the display area is as described above, and the low-resistance line is formed by two or four sides. That is, the liquid "if at least one of the regions has a common line in the display area; and: the agricultural system is in the display area in the storage line, and unexpectedly set a low resistance and low resistance circuit between the secrets Since the second electric circuit is provided on the outer side of the display area, the operation of the common electrode is: electrically connected to the low-resistance line, and the potential of the liquid crystal display having good display quality is obtained. Stability, (Applicable Example 3) is in the above-described application example: The resistive circuit is viewed in a plan view as the display device, and the second electrode on the outer side of the lower side is overlapped and formed to protrude beyond the display area. According to this configuration, a low-lying area is set in a region further than the second resistive line, and the size of the device is shown. 320557 8 200919055 (Application example 4) The front-end electric power is made in the resistive circuit system. In the liquid crystal display device of the above-described application example, the both end portions of the low-resistance-reducing line and the side of the common-line electric _ / the electric circuit are connected to the common end portion. The way the resistance of the second electrode can be In the liquid crystal display device of the application example, the common-resistance line is arranged in parallel with the position of the second line; the low power is good. /, k line is via 逹Between the line and the electrical connection, the low-power second brother and the second road ((4) are in the state of the common lining road and the low-resistance line.

Fig. 10 (4) is a diagram showing a personal $ brain in which a liquid crystal display panel is mounted. Fig. 1G (8) shows an operation in which a liquid crystal display panel is mounted. (Embodiment 1) The FFS mode liquid crystal display of this embodiment is an illusion. It is formed by holding a liquid crystal layer (not shown) between a pair of opposed substrates. Among the pair of substrates, one of the substrates is used as the array substrate AR (see Fig. 3), and the other substrate is formed with a color filter (5). A color dimmer substrate (not shown) such as r(1)(4). " The array substrate AR first forms a conductive layer such as aluminum or aluminum alloy across the entire surface of the transparent substrate n (see Fig. 3) such as a glass substrate. Thereafter, the hunting is performed by a conventional lithography (ph〇tc) 11 th qing aphy) method and a zonal DA is formed in parallel with each other to form a plurality of scanning lines 12. Further, around the display area DA (hereinafter referred to as "frontal area"), 320557 11 200919055 common line 161 and a gate line (not shown) are formed. The gate line is placed closer to the display area μ side than the common line 16ι. Further, as shown in Fig. 2, the first low-resistance line lb, the second low-resistance line lb, and the third low-resistance line ΐβ4. The display area DA controls the area of the liquid crystal molecules of the liquid crystal layer in accordance with the signal for the image input from the outside of the liquid crystal display device 1A. On the other hand, the display area DA is the same as the shape of the rectangular transparent substrate u, and is a horizontally long display area DA. Specifically, the common line 16l is formed thicker than the other lines in such a manner that the display area DA is surrounded by the part TA of the front edge area in which the drive IC and the various terminals are disposed. That is, the common line 16i is formed, for example, as shown in Fig. 2 along the two short sides and one long side of the rectangular transparent substrate u to be outside the display area. The drive 1 (: and various terminals) are disposed on one long side of the transparent substrate 未 in which the common line 1 is not formed. The first and third of the first to third low-resistance lines 162, 163 and 164 are provided. The low-resistance lines 162 and 163 are formed in a "low-resistance line in the column (r〇w, horizontal direction)", and are formed in the row (column direction) on the outer side of the display area DA in the column direction. In other words, the first low-resistance line 162 is formed along the long side of the transparent substrate u and formed in parallel with the common line 161. Further, the area outside the display area DA is along the longitudinal direction of the display area μ. Further, the first low-resistance line 162 is provided in a region outside the display area DA, and is preferably as close as possible to the display area. Therefore, it is preferably displayed on the outermost side in the area DA of the display 320557 12 200919055. It is formed as the longitudinal direction of the domain da. Further, the direction of the display area lamp of the row direction=161 is parallel to the scanning line 12, the signal green is 15 horizontal, and the second and the second low resistance are formed. Line c.: Both ends - body connection The common line 16l. The first and second low-resistance lines extending in the longitudinal direction of the mountain are along the 1 tributary area == are respectively connected to the transparent substrate U ^ 162 and 163. 161. By this way, the ί::? can be used as the second electric=i6r, and the appearance can be made smaller, and the effect can be achieved. Further, as shown in FIG. 2, the first low-resistance line formed on the upper side is the second side in the outer-upper Q-domain, and the third low-resistance 2 system is formed on the pixel line 16". 3 low resistance line 6 4 and electrically connected to the common resistance line. In addition: = 10% of the "outside of the low-power DA in the row direction, because the row-side circuit 164 is in the display area, the row-forming direction is formed in the row direction, and the U-low-power 1a-line 162 is parallel to the third slice. The core is electrically connected by a connection line formed on the transparent substrate 11 and the low-resistance line =: and 62, for example, a vertically extending connection line becomes the low line of the line = 320557 13 200919055, and the third line of the line Low-resistance line! 64. Although the low-resistance line 164 can be formed in each row formed in the display region (1), or in each of the plurality of rows, the manner in which each row of the pixel region formed is formed is It is preferable to reduce the external resistance of the electrode top electrode 22 to be described later. The line 5^1 line 162 is common to the line, and the circuit is provided with an electrostatic protection circuit 3G. Specifically, the static protection The circuit 3 is connected to the end of the signal line 15 and the other is connected to the t-line bee 161. Further, the electrostatic protection circuit is provided in the pixel region ==, and the third low-resistance line 164 is formed on the formed side. The electric protection circuit 3 is located next to it (to avoid the static electricity protection) For the configuration and function of the electrostatic protection circuit 3G, the gate and the protection circuit 3 are connected to the end of the signal line 15 and the common line 161 :: two TFTs (TFn, TFT2). (4), on the side of the common line 16l, the high-frequency material is used to make the charge from the signal line side: the opposite side is turned on the signal line 15 side to become a high-voltage material, as shown in Fig. 6 (8) 1:1. The side of the line 161 is released. That is, the electrostatic protection circuit 30 prevents the breakage of the light component caused by the power generation in the process of the liquid crystal display device 1. The terminal is as described above. The end of the 15 and the unillustrated sweep line 12 are connected to the drive π for inputting the signal, and are connected to the common line by the electrostatic protection circuit 3G. Thus, the time domain DA and There is a certain distance between the common line 16] and the electrostatic protection circuit plus 320557 14 200919055. Therefore, in comparison with the existing common line 16i and the third (lower resistance line 164) It is possible to reduce the power-on: 22: pass two, in order to form a connection portion with the upper electrode 22, which will be described later, from * ==6, there is a connection protruding toward the inner side (the display area Μ side); the ground is formed with a wide connection portion of the second low-throttle diagram). Here, the first low-resistance line and the = 2, the connection portion formed by the low-resistance line 163 and 167_ are formed in each row of the pixel region of the --region DA. ', ~ is formed into two turns, and the entire surface is covered by a nitride layer or an oxide (four) The lower part of the table ^ is covered by, for example, Amorphous Stone (Am〇rph〇us siii_, with TFT 2:^' in the same way by the light lithography method and the money engraving method to form a semi-conductor by a_SU_ The region of the scanning line 12 at the position of the right = Zhao layer 14 forms τη = electrode G (photograph 3 of the photo). J can have half = layer:: plywood sighs the surface of the substrate. Furthermore, the light lithography method and the side method are used to vertically scan the display area DA.

The mode of the open area includes the signal of the source electrode S, the line 15, and is in the TFT

Continue ι / Υ open ^ into; and electrode D. In addition, a source line (not shown) to which the disk signal is connected is formed in the forehead area. In addition, the source U 320557 15 200919055 of the signal line 15 is partially overlapped on the surface of the semiconductor layer 14 by the electrode S portion and the drain electrode d. Thereafter, the entire surface of the transparent substrate 11 obtained by the above process is covered with a passivation film 17. As the passivation film π, a layer composed of a tantalum nitride layer or a hafnium oxide layer can be used, but the tantalum nitride layer is preferable from the viewpoint of insulation. Further, a full-scale layer on the surface of the purification film 17 is, for example, a flattening film (also referred to as an interlayer film) 18 composed of an acrylic resin or a p〇lyimide resin. Next, (1) a j-th contact hole 21a that penetrates the planarizing film 18 and the passivation film 17 to reach the surface of the drain electrode d is simultaneously formed; (2) the planarizing film 18, the passivation film 17, and the gate are formed. The second contact hole 21b reaching the surface of the connection portion 16s of the common line 16] of the pole insulating film 13 reaches the third surface of the connection portion lb of the first low-resistance line Mg, the contact hole 21c, and the second low-resistance line 163. The fourth contact hole 21d of the surface of the connecting portion 16 is a surface. The first to fourth contact holes 21a to 21d are formed by plasma etching using one of dry etching methods. Next, the lower transparent conductive layer composed of IT 0 or IZ 0 is laminated. At this time, the connection portion of the first low-resistance line 1β2 of the connection portion 165' of the lower-long conductive (four) system Wei D and the common line ^ The connection portion 167 of the line 163 of i6e, ' is electrically connected. Then, by the _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ And the second low-voltage lower transparent conductive layer 19a is further connected to the common line 161 by 320557 16 200919055 portion 16s, the first low-resistance line 16z connecting portion 16s, and the second low-resistance line 16" The structure formed by the connecting portion 16 is formed to be substantially the same even if the shape and size of the contact holes are different. Further, in the liquid crystal display device 10 of the embodiment, the lower electrode 19 corresponds to the pixel electrode. Further, the insulating film 20 made of a nitrogen-cut layer or an oxygen-cut layer of a county thickness is formed by arranging the entire surface of the transparent substrate 11 on which the lower electrode 19 is formed. The insulating film 20 is formed so as not to be damaged by the conditions for forming the gate insulating film 13 or the passivation film 17, that is, the so-called low-temperature film forming conditions, so that the surfaces of the planarizing film 18 and the lower electrode 19 are not damaged. . Then, the insulating film formed in the second contact hole 21b, the third contact hole 21C, and the fourth contact hole 2id is removed from the surface of the insulating film 20. Further, the lower transparent conductive layer 19a in the second to fourth contact holes 21b to (10) is exposed. Thereafter, a transmissive f. layer composed of ITG or iZG is formed across the entire surface of the transparent substrate 12. At this time, by the transparent conductive layer, the 2nd to 4th contact holes are trained to 2η to make the second and the second! The low-resistance line 1β2 and the second low-resistance line are electrically connected to each other. Thereafter, the transparent conductive phase layer is left by the photolithography method and the silver etching method, whereby the entire display region is covered with the transparent conductive layer. Further, the upper electrode 22 having the plurality of rides 24 which generate the edge electric power is formed in the permeable layer. The surface of the connection portion 16 of the contact portion 165 and the first low-resistance line 166 via the lower transparent conductive layer is connected to the surface of the connection portion 16 of the resistive line 163 via the lower transparent conductive layer. Electrical connection 320557 17 200919055 status. The liquid crystal display device of the embodiment corresponds to a common electrode. In the 'reading, if you want to reduce the resistance of the upper electrode 22 ----- limit, ^ the transparent conductive layer extends along the transparent substrate U, the upper electrode is on the line, and the position is made A military connection formed by the upper electrode side is also conceivable. However, as described above, there is a distance between the display area DA and the common line 161 between the common line (10) and the common line 16]. Therefore, the display area may be close to the display. In the vicinity of the region M, the upper electrode-I line 161 is electrically connected, and the upper electrode 22 and the common line W are electrically connected to the low resistance line 162. The manner in which the upper electrode 22 is formed to extend in a plan view is preferable. The other line 162 and the second low-resistance line 163 are at the second position: the first low-resistance 1 low-resistance line 162 and the second low-power. Thereby, the liquid helium path 163 can be set smaller than the upper electrode than when the area outside the 22nd is outside. The liquid display device 1 is displayed. In addition, on the common line 16, above, a transparent Vase 22 of the Vase 22 does not). Since it is known that the adhesion between the upper sealing members of the upper electrode is not good, it is as good as possible. ^ Subtract material is better. In this regard, the above is also very excellent 21 (i, and the upper private pole 22 is connected to the first low-resistance line 162 and the second low-resistance line 163 via the second to fourth contact holes 21b to the phase-electric far-piles 14 The state of the connection. Thereafter, the actual array substrate AR is completed by providing an alignment film (not shown) on the surface of the upper electrode 22, 320557 18 200919055. The prism display device is opposed to the aforementioned array plate AR. Although it is abbreviately shown, it is also possible to use the same color filter substrate as the conventional FFS color filter substrate, that is, the liquid crystal display panel and the pixel electrode are used as the pixel electrode. ^% The position of the color chopper substrate forms a color filter layer of each color, and the opposite surface of the lower electrode 19 has an alignment film. Moreover, in the color filter layer=color; the surface of the photoreceptor layer A black matrix is respectively disposed on the phase of the scanning line 12 and the signal line 15 and between the substrates to be aligned. Then, the position of the color filter substrate relative to the TF τ can be obtained. ^In the internal sealing board AR and color liquid crystal display device 10. 'The crystal to obtain the basis of the example The (four) example electrode 22 manufactured by the above-mentioned method is connected to the display device 1 〇, the _way 161, the first low-resistance line Ik, and the first through the second to fourth contact holes 21 b to the common electrode. When the second low-resistance line lf and the second low-resistance line 163 and the common line 1 are resistive lines le, the first low-resistance line 162 is connected via the third low-electrode-connected g. In a state in which the common line 16l is electrically connected to the common line 164, the common line Φ is connected to the upper electrode via a plurality of contact holes, so that the upper electrode 22 is connected to each other in order to prevent image sticking. The resistance also becomes very small in appearance. Thus, the upper electrode liquid crystal display panel is not applied to the signal of the pole U according to the embodiment, so even if it is a horizontally long row, Power-on 曰碲 does not install its horizontal 32〇 557 19 200919055 direction crosstalk is also small, resulting in. _, if it is a small good liquid crystal display device, especially the impact may be less, but for example, 6 two? Large liquid crystal on top of the resistance value Medium-sized, or the effect of the resistance of the upper electrode 22 becomes greater, no, set, and the upper electrode 22 = pay more for the medium-sized, large-scale liquid crystal display transposition is more 'in the implementation of the above, in the formation of transparent Before the conductive layer, there is a step of removing the insulating film formed in the second contact hole 21b and the third contact hole 21 in the hole (10) by a meal. However, this step also does not mean "| In the forehead region, the material ta simultaneously forms a step for driving the mounting terminal, the inspection terminal, the external connection terminal, and the like (all are not shown). Therefore, a new step is not added. The first low-resistance line 162, the second low-resistance line 163, and the third low-resistance line 164 may be formed of the same material as the scanning line 12, or may be formed of the same material as the signal line 15. Thereby, the formation of the scanning line 12 and the signal line 15 can be simultaneously performed, so that the manufacturing process can be easily performed without changing the manufacturing steps. A schematic cross-sectional view corresponding to the figure of Shouji 8 is shown in FIG. g. The common line 161, the first low-resistance line 162, the second low-resistance line 16s, and the third low-resistance line 164 are formed in the gate. The surface of the pole insulating film 13. Further, the common line 16! 'the first low-resistance line 16z, the second low-resistance line 163, and the third low-resistance line 164 may all be formed of the same material as the signal line 15, or may be only a part It is formed of the same material as the signal line 15. 20 320557 ZUUVIVUD^ Above, the LCD display in FFS mode is used for explanation. In the case of the above-mentioned liquid crystal display, the mobile phone, the mobile information terminal, and the like are used as an implementation power: a personal computer is used, and (A) a display unit (liquid crystal display panel) is shown. In the example of Fig. 10, the example shown in Fig. 10(B) shows that the board used in the personal computer 70) 76 is used in a mobile phone, and the basic configuration of the liquid crystal display surface and the mobile phone 75 is shown. However, the personal computer 7 is described (the detailed description of the personal computer 7 is explained by the industry.
