[0056] <First Embodiment>

[0057] Through Figures 1 to 11 The first embodiment will be described. In this embodiment, the liquid crystal display device 10 will be exemplified. In addition, the X-axis, Y-axis, and Z-axis are shown in a part of each drawing, and the description will be made in such a way that the directions of the respective axes become the directions shown in each drawing.

[0058] The liquid crystal display device 10 of this embodiment is a type of 3D image display device that allows a user to visually recognize a 3D image (stereoscopic image), and adopts an active retarder method. As Figure 1 shown, the liquid crystal display device 10 includes at least: a liquid crystal panel (display device, display panel) 11 that can display an image; a backlight device (lighting device) 12 that is disposed on the back side (rear side) with respect to the liquid crystal panel 11; and a sub-liquid crystal panel 13 that is disposed on the front side (front side) with respect to the liquid crystal panel 11. The backlight device 12 is an external light source that irradiates the liquid crystal panel 11 with light for display. The backlight device 12 has a light source (such as an LED, etc.) that emits white light (white light), an optical component that converts the light from the light source into planar light by imparting an optical effect, and the like.

[0059] The sub-liquid crystal panel 13 functions as a modulator for converting linearly polarized light emitted from the liquid crystal panel 11 into circularly polarized light. Specifically, the sub-liquid crystal panel 13 can switch between right-handed circularly polarized light and left-handed circularly polarized light in synchronization with the liquid crystal panel 11 that alternately displays a right-eye image and a left-eye image. In this liquid crystal display device 10, circularly polarized glasses equipped with a circularly polarized film with reverse rotation directions of left and right are used in combination. The user can visually recognize a 3D image by observing the liquid crystal display device 10 while wearing the above-mentioned circularly polarized glasses. In this way, since the sub-liquid crystal panel 13 is driven at high speed in synchronization with the display of the liquid crystal panel 11, a large amount of noise is input from the front side to the liquid crystal panel 11 disposed close to the sub-liquid crystal panel 13.

[0060] Next, the configuration of the liquid crystal panel 11 used in the liquid crystal display device 10 of the active retarder method will be described. First, Figure 2 A schematic overview of the planar configuration of the liquid crystal panel 11 will be described. As Figure 2As shown, the liquid crystal panel 11 is overall square. The central side portion of the screen of the liquid crystal panel 11 is a display area AA for displaying an image. The display area AA is formed as a square that is one circle smaller than the outer shape of the liquid crystal panel 11. The outer peripheral side portion of the liquid crystal panel 11 in the form of a frame surrounding the display area A in the screen is a non-display area NAA that does not display an image. The non-display area NAA is set in the form of a square frame. In addition, in Figure 2 the range surrounded by the single dotted line is the display area AA.

[0061] As Figure 2 shown, the liquid crystal panel 11 has a pair of substrates 11A and 11B made of glass that are almost transparent and have excellent light transmittance. Among the pair of substrates 11A and 11B, the substrate arranged on the front side is the counter substrate (second substrate, CF substrate) 11A, and the substrate arranged on the back side is the array substrate (first substrate, active matrix substrate) 11B. The planar shapes of the counter substrate 11A and the array substrate 11B are both square, and each has a pair of side portions 11A1 and 11B1 along the X-axis direction and a pair of side portions 11A2 and 11B2 along the Y-axis direction (refer to Figure 6 and Figure 7 ). Among them, the array substrate 11B is larger than the counter substrate 11A, and a part of it protrudes laterally with respect to the counter substrate 11A. A driver (panel driving component) 14 and a flexible substrate (signal transmission component) 15 are mounted on the protruding portion 11B3 of the array substrate 11B. The driver 14 is composed of an LSI chip having a driving circuit inside. The driver 14 processes various signals transmitted by the flexible substrate 15. The driver 14 is mounted on the protruding portion 11B3 of the array substrate 11B by COG (Chip On Glass). The flexible substrate 15 is configured to have a plurality of wiring patterns formed on a substrate having insulation and flexibility. One end side of the flexible substrate 15 is connected to the array substrate 11B, and the other end side is connected to an external control substrate (signal supply source). Various signals supplied from the control substrate are transmitted to the liquid crystal panel 11 via the flexible substrate 15.

[0062] Next, Figure 3 is used to Figure 3As shown, a pair of substrates 11A and 11B are arranged to face each other with a gap therebetween in the normal direction of the plate surfaces of the substrates 11A and 11B, i.e., in the Z-axis direction. Between the pair of substrates 11A and 11B, at least a liquid crystal layer 11C and a sealing portion 11D for encapsulating (sealing) the liquid crystal layer 11C are provided. The liquid crystal layer 11C contains a substance whose optical properties change with the application of an electric field, i.e., liquid crystal molecules. The sealing portion 11D is disposed near the non-display area NAA, i.e., the outer peripheral end portion, of the two substrates 11A and 11B, and is provided in a form that extends over the entire circumference of the outer peripheral end portion. The sealing portion 11D has a square frame shape (endless ring shape) when viewed from above as a whole, and surrounds the liquid crystal layer 11C (display area AA) over the entire circumference. Through this sealing portion 11D, a gap (cell gap) for maintaining the thickness of the liquid crystal layer 11C is held at the outer peripheral end portions of the two substrates 11A and 11B. Polarizing plates 11E are respectively pasted on the outer surface sides of the pair of substrates 11A and 11B. The pair of polarizing plates 11E are arranged such that their transmission axes (absorption axes) are orthogonal to each other, i.e., in a crossed Nicol configuration.

[0063] Next, Figure 4 the pixel arrangement of the display area AA of the array substrate 11B will be described. As Figure 4As shown, a plurality of gate wirings (scanning wirings) 16 and a plurality of source wirings (image wirings) 17 are arranged in a grid pattern on the inner surface side of the display area AA of the array substrate 11B. TFTs (thin film transistors) 18 and pixel electrodes 19 are provided near the intersection of the gate wirings 16 and the source wirings 17. The gate wirings 16 extend approximately along the X-axis direction in the form of crossing the display area A and are connected to the gate 18A of each TFT18. A plurality of gate wirings 16 are arranged at intervals along the Y-axis direction. The gate wirings 16 are formed by patterning a metal film composed of a metal material using a known photolithography method. The source wirings 17 extend approximately along the Y-axis direction in the form of vertically crossing the display area AA and are connected to the source 18B of each TFT18. A plurality of source wirings 17 are arranged at intervals along the X-axis direction. The source wirings 17 are formed by patterning a metal film composed of a metal material using a known photolithography method. The source wiring 17 is located on the upper side (the liquid crystal layer 11C side, the side close to the relative substrate 11A) with an insulating film between it and the gate wiring 16. TFT18 and pixel electrodes 19 are regularly arranged in multiples along the X-axis direction and the Y-axis direction, and are arranged in a matrix (row and column) in a plane. The pixel electrode 19 is connected to the drain 18C of TFT18. The pixel electrode 19 is formed by patterning a transparent electrode film composed of a transparent electrode material such as ITO (Indium Tin Oxide) using a known photolithography method. The pixel electrode 19 is located on the upper side with an insulating film between it and the source wiring 17. In addition to having the above-mentioned gate 18A, source 18B and drain 18C, TFT18 also has a channel portion 18D. The channel portion 18D is composed of a semiconductor material and is connected to the source 18B and the drain 18C. Moreover, when TFT18 is driven based on the scanning signal supplied to the gate wiring 16, the pixel electrode 19 is charged to a potential based on the image signal (data signal) supplied to the source wiring 17. The gate wiring 16, source wiring 17, and TFT 18 constitute a pixel circuit portion 20 (see FIG. Figure 5 ).

[0064] Next, use Figure 5 The structure of the display area AA of the liquid crystal panel 11 will be described. Figure 5 In FIG. 1 , the structure in the display area AA of the liquid crystal panel 11 is simplified. Figure 5 As shown, pixel electrodes 19 and a pixel circuit unit 20 are provided on the inner surface side of the display area AA of the array substrate 11B. At least a color filter 21, a light shielding unit (black matrix) 22, and a first electrode (counter electrode) 23 are provided on the inner surface side of the display area AA of the counter substrate 11A.

[0065] The color filter 21 relative to the substrate 11A is arranged in a form overlapping with the pixel electrode 19 of the array substrate 11B, presenting three colors of red (R), green (G), and blue (B). The mutually opposed color filter 21 and pixel electrode 19 constitute a pixel as a display unit. In addition, in addition to red (R), green (G), and blue (B), a color filter 21 of four colors including yellow (Y) and white (W) is sometimes provided. The light-shielding portion 22 is in a lattice shape so as to space adjacent color filters 21 apart, and functions to prevent color mixing between pixels and the like. The first electrode 23 is provided in a planar shape at least in the display area AA, and is opposed to all the pixel electrodes 19 with the liquid crystal layer 11C interposed therebetween. By supplying a common potential (reference potential) to the first electrode 23, a potential difference is generated between the first electrode 23 and the pixel electrode 19 charged by the pixel circuit portion 20. The alignment state of the liquid crystal molecules in the liquid crystal layer 11C changes based on this potential difference, whereby a prescribed gray-scale display can be performed for each pixel. The first electrode 23, like the pixel electrode 19, is formed by patterning a transparent electrode film (second transparent electrode film) made of a transparent electrode material such as ITO (Indium Tin Oxide) by a known photolithography method.

[0066] The planar shape of the pixel electrode 19 of the array substrate 11B is square, and has a plurality of slits 19A extending in a radially expanding manner from its center. The extending directions of the plurality of slits 19A are different according to the position of the pixel electrode 19 in the plane. That is, it can be said that the pixel electrode 19 is divided into a plurality of (for example, four) domains in which the extending directions of the slits 19A are different from each other. Here, local recesses (absent portions of the pixel electrode 19) are formed at positions on the surface of the array substrate 11B that overlap the above-described slits 19A. Therefore, when the pixel electrode 19 is charged, an electric field corresponding to the recess shape based on the slit 19A is generated from the inner surface of the array substrate 11B. The liquid crystal molecules contained in the liquid crystal layer 11C are aligned along the recesses on the inner surface of the array substrate 11B. As described above, the display mode of the liquid crystal panel 11 of the present embodiment is an MVA (Multi-domain Vertical Alignment) mode in which the alignment of the liquid crystal molecules contained in the liquid crystal layer 11C is different in each domain of the pixel electrode 19. Thereby, wide viewing angle conversion is achieved.

[0067] As described above, the noise generated from the sub liquid crystal panel 13 is likely to be input from the front side into the liquid crystal panel 11. Due to this noise, there may be a potential change in the first electrode 23 with respect to the substrate 11A. If a potential change occurs in the first electrode 23, the potential difference generated between the first electrode 23 and the pixel electrode 19 will change, and problems such as instability of the display gray scale of the pixel and deterioration of the display quality may occur. Therefore, on the substrate 11A of the present embodiment, a second electrode (shielding electrode, electrostatic capacitance electrode) 24 for shielding the noise that can be input into the first electrode 23 is provided. The second electrode 24 is provided in a full-surface shape at least in the display area AA, and is arranged to overlap the second electrode 23 in a plan view. The second electrode 24, like the pixel electrode 19 and the first electrode 23, is formed by patterning a transparent electrode film (first transparent electrode film) made of a transparent electrode material such as ITO (Indium Tin Oxide) using a known photolithography method. A ground potential is supplied to the second electrode 24. On the substrate 11A, an insulating film 25 is provided in the Z-axis direction between the first electrode 23 and the second electrode 24. The second electrode 24 is located on the lower layer side of the insulating film 25 (the side opposite to the liquid crystal layer 11C, the side far from the array substrate 11B). That is, the second electrode 24 is arranged on the lower layer side of the first electrode 23 with the insulating film 25 interposed therebetween, that is, on the side closer to the sub liquid crystal panel 13 which is the noise generation source. Therefore, the noise (external noise) generated from the sub liquid crystal panel 13 is input into the second electrode 24 before the first electrode 23, and thus the noise can be well shielded by the second electrode 24 having a ground potential. The first electrode 23 is located on the upper layer side of the insulating film 25 (the liquid crystal layer 11C side, the side close to the array substrate 11B). That is, the first electrode 23 is arranged on the upper layer side of the second electrode 24 with the insulating film 25 interposed therebetween. Therefore, it is possible to prevent the electric field generated between the first electrode 23 and the pixel electrode 19 from being shielded by the second electrode 24. Moreover, since the insulating film 25 is provided between the mutually overlapping first electrode 23 and the second electrode 24, an electrostatic capacitance is formed between the first electrode having a common potential and the second electrode having a ground potential. Thereby, the potential change of the first electrode 23 can be suppressed.

[0068] Next, Figure 6 and Figure 8 the configuration of the non-display area NAA of the array substrate 11B will be described. As Figure 6As shown, a first wiring 26 for supplying a common potential to the first electrode 23 and a second wiring 27 for supplying a ground potential to the second electrode 24 are provided in a non-display area NAA of the array substrate 11B. The first wiring 26 and the second wiring 27 are formed by patterning a metal film identical to the gate wiring 16 and the source wiring 17 by a known photolithography method. That is, when manufacturing the array substrate 11B, the first wiring 26 and the second wiring 27 are formed in the same process as the process of forming the gate wiring 16 and the source wiring 17. The first wiring 26 and the second wiring 27 may be composed of the same metal film or may be composed of mutually different metal films. The first wiring 26 and the second wiring 27 are provided in a portion of the non-display area NAA of the array substrate 11B that overlaps with the opposing substrate 11A. The first wiring 26 and the second wiring 27 are located between the display area AA and the side portions (end portions) 11B1, 11B2 of the array substrate 11B in the non-display area NAA of the array substrate 11B. The first wiring 26 and the second wiring 27 are arranged at intervals and extend in a parallel manner to each other. The first wiring 26 and the second wiring 27 each extend along the four side portions 11B1, 11B2 of the array substrate 11B, and four of each are provided. Each of the four first wirings 26 and the four second wirings 27 includes two first wirings 26 and two second wirings 27 that extend in the X-axis direction and two first wirings 26 and two second wirings 27 that extend in the Y-axis direction. The ends of the four first wirings 26 are connected to each other and form a square frame shape (endless loop shape) in a plan view to surround the display area AA as a whole. The ends of the four second wirings 27 are connected to each other and form a square frame shape (endless loop shape) in a plan view to surround the display area AA as a whole. It can be said that each of the four first wirings 26 and the four second wirings 27 is parallel to the sealing portion 11D. The first wiring 26 is arranged on the side closer to the display area AA (inner peripheral side) with respect to the second wiring 27. The second wiring 27 is arranged on the side farther from the display area AA (outer peripheral side) with respect to the first wiring 26.

[0069] As Figure 8 shown, the first wiring 26 and the second wiring 27 are arranged at positions that do not overlap with the sealing portion 11D. In Figure 8In [the figure], the sealing portion 11D is illustrated by a double-dashed line. The first wiring 26 and the second wiring 27 are arranged with an interval greater than the width of the sealing portion 11D. The interval between the first wiring 26 and the second wiring 27 is substantially constant throughout the entire length. The first wiring 26 is arranged at an interval with respect to the sealing portion 11D on the side closer to the display area AA. The second wiring 27 is arranged at an interval with respect to the sealing portion 11D on the side farther from the display area AA (closer to the side portions 11B1 and 11B2 of the array substrate 11B). The first connection electrode 28 protruding toward the second wiring 27 side (the side farther from the display area AA) is electrically connected to the first wiring 26. The first connection electrode 28 is formed of the same metal film as the first wiring 26 and is connected to the first wiring 26. Therefore, when manufacturing the array substrate 11B, the first connection electrode 28 is formed by the same process as forming the first wiring 26. The first connection electrode 28 extends from the first wiring 26 in a direction crossing the extending direction of the first wiring 26 (the Y-axis direction in [a certain context]). The first connection electrodes 28 are arranged at intervals in the extending direction of the first wiring 26. The arrangement interval of the plurality of first connection electrodes 28 is greater than the width of the second connection electrode 29. The second connection electrode 29 protruding toward the first wiring 26 side (the side closer to the display area AA) is electrically connected to the second wiring 27. In this way, the first connection electrode 28 and the second connection electrode 29 are arranged sandwiching the first wiring 26 and the second wiring 27, so the space efficiency is good, and it is preferable for realizing the narrow bezel of the liquid crystal panel 11. The second connection electrode 29 is formed of the same metal film as the second wiring 27 and is connected to the second wiring 27. Therefore, when manufacturing the array substrate 11B, the second connection electrode 29 is formed by the same process as forming the second wiring 27. The second connection electrode 29 extends from the second wiring 27 in a direction crossing the extending direction of the second wiring 27. The second connection electrodes 29 are arranged at intervals in the extending direction of the second wiring 27. The arrangement interval of the plurality of second connection electrodes 29 is greater than the width of the first connection electrode 28. The first connection electrode 28 and the second connection electrode 29 are arranged in the area (space) sandwiching the first wiring 26 and the second wiring 27. The first connection electrode 28 and the second connection electrode 29 are arranged in the extending direction of the first wiring 26 and the second wiring 27. The plurality of first connection electrodes 28 and the plurality of second connection electrodes 29 are arranged alternately one by one in the extending direction of the first wiring 26 and the second wiring 27. The plurality of first connection electrodes 28 and the plurality of second connection electrodes 29 are arranged to overlap the sealing portion 11D in a top view. Figure 8 In [a certain context] Figure 8 In [a certain context]

[0070] In addition, on the protruding portion 11B3 that does not overlap with the opposing substrate 11A in the non-display area NAA of the array substrate 11B, as Figure 6As shown, extraction wirings 26A and 27A are respectively provided which are extracted from the first wiring 26 and the second wiring 27. These at least a pair of extraction wirings 26A and 27A are wired in such a manner as to reach the mounting area of the driver 14 or the flexible substrate 15, and are connected to at least a pair of terminal portions provided in this mounting area. The common potential or the ground potential is supplied to these terminal portions from the driver 14 or the flexible substrate 15.

[0071] Next, use Figure 7 and Figure 9 to explain the configuration of the non-display area NAA of the opposing substrate 11. As Figure 7 shown, in the non-display area NAA of the opposing substrate 11, a third connection electrode 30 that conducts with the first electrode 23 and a fourth connection electrode 31 that conducts with the second electrode 24 are provided. First, the planar shapes of the first electrode 23 and the second electrode 24 are both square, and are one circle larger than the display area AA. The central side portion of the first electrode 23 is disposed overlapping the entire area of the display area AA, while the outer peripheral side portion is disposed in the non-display area NAA. The second electrode 24 is the same as the first electrode 23, and the central side portion is disposed overlapping the entire area of the display area AA, while the outer peripheral side portion is disposed in the non-display area NAA. That is, both the first electrode 23 and the second electrode 24 have a formation range that straddles the display area AA and the non-display area NAA.

[0072] As Figure 7 shown, the third connection electrode 30 is located between the first electrode 23 and the side portions (end portions) 11A1 and 11A2 of the opposing substrate 11A in the non-display area NAA of the opposing substrate 11A. The third connection electrode 30 conducts with the end portion of the first electrode 23. That is, the third connection electrode 30 is provided so as to protrude outward from the end portion of the first electrode 23. A plurality of the third connection electrodes 30 are arranged at intervals in the direction (X-axis direction or Y-axis direction) along the end portion of the first electrode 23. The third connection electrode 30 is provided over the entire circumference of the outer peripheral end portion formed by the four end portions of the first electrode 23. That is, a plurality of the third connection electrodes 30 are respectively provided at the four end portions constituting the outer peripheral end portion of the first electrode 23. The fourth connection electrode 31 is located between the second electrode 24 and the side portions (end portions) 11A1 and 11A2 of the opposing substrate 11A in the non-display area NAA of the opposing substrate 11A. The fourth connection electrode 31 conducts with the end portion of the second electrode 24. That is, the fourth connection electrode 31 is provided so as to protrude outward from the end portion of the second electrode 24. A plurality of the fourth connection electrodes 31 are arranged at intervals in the direction along the end portion of the second electrode 24. The fourth connection electrode 31 is provided over the entire circumference of the outer peripheral end portion formed by the four end portions of the second electrode 24. That is, a plurality of the fourth connection electrodes 31 are respectively provided at the four end portions constituting the outer peripheral end portion of the second electrode 24.

[0073] As Figure 9 shown, the outer peripheral ends of the first electrode 23 and the second electrode 24 are located on the inner peripheral side (display area AA side) relative to the sealing portion 11D and do not overlap with the sealing portion 11D. In Figure 9 it, the sealing portion 11D is illustrated by a dashed double-dotted line. The third connection electrode 30 extends from the first electrode 23 in a direction crossing the direction along the end of the first electrode 23 (the Y-axis direction in Figure 9 it) (the X-axis direction in Figure 9 it). A plurality of third connection electrodes 30 are arranged at intervals in the direction along the end of the first electrode 23. The arrangement interval of the plurality of third connection electrodes 30 is larger than the width of the fourth connection electrode 31. The fourth connection electrode 31 extends from the second electrode 24 in a direction crossing the direction along the end of the second electrode 24 (the Y-axis direction in Figure 9 it) (the X-axis direction in Figure 9 it). A plurality of fourth connection electrodes 31 are arranged at intervals in the direction along the end of the second electrode 24. The arrangement interval of the plurality of fourth connection electrodes 31 is larger than the width of the third connection electrode 30. The third connection electrode 30 and the fourth connection electrode 31 are arranged in the direction along the respective ends of the first electrode 23 and the second electrode 24. The plurality of third connection electrodes 30 and the plurality of fourth connection electrodes 31 are arranged one by one alternately in the direction along the respective ends of the first electrode 23 and the second electrode 24. The plurality of third connection electrodes 30 and the plurality of fourth connection electrodes 31 are arranged so as to overlap the sealing portion 11D in a plan view.

[0074] Next, use Figure 10 to illustrate the relationship between the first connection electrode 28 and the third connection electrode 30. First, as Figure 10As shown, a light-shielding portion 22 is formed in a substantially entire area in a planar shape on the non-display area NAA of the opposing substrate 11. By the planar light-shielding portion 22 disposed in the non-display area NAA, it is possible to avoid the light from being emitted from the non-display area NAA. Thereby, the display quality of the image displayed in the display area AA is good. The third connection electrode 30 is disposed overlapping the first connection electrode 28. That is, the third connection electrode 30 and the first connection electrode 28 are relatively disposed with a space therebetween in the Z-axis direction. The third connection electrode 30 is located on the lower layer side of the insulating film 25, that is, in the same layer as the second electrode 24. The third connection electrode 30 is separated from the second electrode 24 in the same layer. The third connection electrode 30 is formed of the same transparent electrode film as the second electrode 24 and is formed of a portion different from the second electrode 24 in the transparent electrode film. Therefore, when manufacturing the opposing substrate 11A, the third connection electrode 30 is formed by the same process as forming the second electrode 24. Although most of the third connection electrode 30 does not overlap with the first electrode 23, a part thereof is disposed overlapping the first electrode 23 with the insulating film 25 therebetween. Specifically, the end portion on the display area AA side of the third connection electrode 30 overlaps with the end portion of the first electrode 23, and the insulating film 25 is present therebetween. In a portion of the insulating film 25 overlapping the overlapping portion of the first electrode 23 and the third connection electrode 30, a contact hole 25A for conducting the first electrode 23 and the third connection electrode 30 is provided. The end portion on the display area AA side of the third connection electrode 30 and the end portion of the first electrode 23 are conducted through the contact hole 25A of the insulating film 25.

[0075] As Figure 10As shown, most of the portion of the third connection electrode 30 that does not overlap with the first electrode 23 is disposed overlapping the sealing portion 11D. Here, the sealing portion 11D is composed of a base material 11D1 and a plurality of conductive particles 11D2. The base material 11D1 is composed of a photocurable resin material, a thermosetting resin material, etc., and the plurality of conductive particles 11D2 are dispersedly incorporated in the base material 11D1. The conductive particles 11D2 are formed by subjecting the surface of particles made of, for example, synthetic resin to a conductive plating treatment such as gold plating. The particle diameter of the conductive particles 11D2 is set to a value approximate to the cell gap of the liquid crystal panel 11. Among the plurality of conductive particles 11D2, there are conductive particles that form a positional relationship of overlapping with the first connection electrode 28 and the third connection electrode 30. The conductive particles 11D2 that form a positional relationship of overlapping with the first connection electrode 28 and the third connection electrode 30 constitute a first conductive portion 32 that contacts the first connection electrode 28 and the third connection electrode 30. Through the first conductive portion 32, conduction between the first connection electrode 28 and the third connection electrode 30 is achieved. Thus, a common potential is supplied to the first electrode 23 from the plurality of first connection electrodes 28 respectively connected to the plurality of (four) first wirings 26 that surround the first electrode 23 throughout the entire circumference, via the plurality of first conductive portions 32 and the plurality of third connection electrodes 30. As a result, since it is difficult for the resistance distribution of the first electrode 23 to deviate, even when the potential of the first electrode 23 changes due to noise input from the sub liquid crystal panel 13 or the like, the potential of the first electrode 23 can be quickly restored to the original common potential. Therefore, the display quality of the liquid crystal panel 11 becomes good. Moreover, the first conductive portion 32 disposed overlapping the first connection electrode 28 and the third connection electrode 30 is disposed non-overlapping with the second electrode 24. Therefore, even if the number of the connection portions (the first connection electrode 28, the first conductive portion 32, and the third connection electrode 30) of the first wiring 26 and the first electrode 23 increases as described above, it is possible to avoid a short circuit between the third connection electrode 30 and the second electrode 24 due to the first conductive portion 32. Through the above, improvement in connection reliability can be achieved. In addition, although the end portion of the third connection electrode 30 on the side opposite to the display region AA side does not overlap with the sealing portion 11D, it is covered with the insulating film 25. Thus, the end portion of the third connection electrode 30 located outside the sealing portion 11D can be protected by the insulating film 25.

[0076] Next, the relationship between the second connection electrode 29 and the fourth connection electrode 31 will be described. As Figure 11 shown in Figure 11As shown, the fourth connection electrode 31 is disposed overlapping the second connection electrode 29. That is, the fourth connection electrode 31 is disposed opposite to the second connection electrode 29 with a gap therebetween in the Z-axis direction. The fourth connection electrode 31 is located on the lower layer side of the insulating film 25, that is, the same layer as the second electrode 24. The fourth connection electrode 31 is formed of the same transparent electrode film as the second electrode 24 and is formed of a part different from the second electrode 24 in the transparent electrode film. Therefore, when manufacturing the opposing substrate 11A, the fourth connection electrode 31 is formed by the same process as forming the second electrode 24. The end portion of the fourth connection electrode 31 on the display region AA side is connected to the end portion of the second electrode 24 in the same layer, thereby achieving conduction between the fourth connection electrode 31 and the second electrode 24. In addition, although the fourth connection electrode 31 is disposed such that the end portion on the display region AA side overlaps the first electrode 23, the remaining portion is located outside (on the side opposite to the display region AA side) of the end portion of the first electrode 23 and does not overlap the first electrode 23.

[0077] As Figure 11As shown, most of the portion of the fourth connection electrode 31 that does not overlap with the first electrode 23 is disposed to overlap with the sealing portion 11D. Among the plurality of conductive particles 11D2 included in the sealing portion 11D, there are conductive particles that form a positional relationship of overlapping with the second connection electrode 29 and the fourth connection electrode 31. The conductive particles 11D2 that form a positional relationship of overlapping with the second connection electrode 29 and the fourth connection electrode 31 constitute a second conductive portion 33 that contacts the second connection electrode 29 and the fourth connection electrode 31. The conduction between the second connection electrode 29 and the fourth connection electrode 31 is achieved through the second conductive portion 33. In this way, the ground potential is supplied to the second electrode 24 from the plurality of second connection electrodes 29 respectively connected to the plurality of (four) second wirings 27 that surround the second electrode 24 throughout the entire circumference via the plurality of second conductive portions 33 and the plurality of fourth connection electrodes 31. Therefore, since the resistance distribution of the second electrode 24 is less likely to deviate, even when the potential of the second electrode 24 changes due to noise input from the sub liquid crystal panel 13 or the like, the potential of the second electrode 24 can be quickly restored to the original ground potential. Moreover, the second conductive portion 33 disposed to overlap with the second connection electrode 29 and the fourth connection electrode 31 is disposed so as not to overlap with the first electrode 23. Therefore, even if the number of the conduction portions (the second connection electrode 29, the second conductive portion 33, and the fourth connection electrode 31) between the second wiring 27 and the second electrode 24 increases as described above, it is possible to avoid the short circuit between the fourth connection electrode 31 and the first electrode 23 due to the second conductive portion 33. In this way, the connection reliability can be improved. In addition, although the end portion of the fourth connection electrode 31 on the side opposite to the display region AA side does not overlap with the sealing portion 11D, it is covered with the insulating film 25. In this way, the end portion of the fourth connection electrode 31 located outside the sealing portion 11D can be protected by the insulating film 25.

[0078] In addition, as Figure 10 and Figure 11 shown, both the third connection electrode 30 and the fourth connection electrode 31 are located in the same layer as the second electrode 24. The first connection electrode 28 and the second connection electrode 29 are located in the same layer as each other. Therefore, the Z-axis direction interval between the mutually opposed first connection electrode 28 and the third connection electrode 30 and the Z-axis direction interval between the mutually opposed second connection electrode 29 and the fourth connection electrode 31 are substantially the same. Thereby, the first conductive portion 32 interposed between the first connection electrode 28 and the third connection electrode 30 and the second conductive portion 33 interposed between the second connection electrode 29 and the fourth connection electrode 31 can have substantially the same height. The first conductive portion 32 and the second conductive portion 33 are, as described, a part of the plurality of conductive particles 11D2 contained in the sealing portion 11D. Therefore, it is sufficient to include conductive particles 11D2 of one particle size in the sealing portion 11D, which can reduce the material cost and improve the connection reliability.

[0079] As described in the above explanation, the liquid crystal panel (display device) 11 of the present embodiment includes: an array substrate (first substrate) 11B; a counter substrate (second substrate) 11A disposed opposite to the array substrate 11B; a first wiring 26 provided on the array substrate 11B; a second wiring 27 provided on the array substrate 11B, disposed at a position spaced apart from the first wiring 26, and extending in parallel with the first wiring 26; a first connection electrode 28 protruding from the first wiring 26 toward the second wiring 27 side; a second connection electrode 29 protruding from the second wiring 27 toward the first wiring 26 side and arranged in the extending direction of the first connection electrode 28 and the second wiring 27; a first electrode 23 provided on the counter substrate 11A; a third connection electrode 30 provided on the counter substrate 11A, electrically connected to the first electrode 23, and disposed overlapping the first connection electrode 28; a second electrode 24 provided on the counter substrate 11A; a fourth connection electrode 31 provided on the counter substrate 11A, electrically connected to the second electrode 24, and disposed overlapping the second connection electrode 29 and arranged in parallel with the third connection electrode 30 in the extending direction; a first conductive portion 32 disposed between the array substrate 11B and the counter substrate 11A, disposed overlapping the first connection electrode 28 and the third connection electrode 30, and in contact with the first connection electrode 28 and the third connection electrode 30; a second conductive portion 33 disposed between the array substrate 11B and the counter substrate 11A, disposed overlapping the second connection electrode 29 and the fourth connection electrode 31, and in contact with the second connection electrode 29 and the fourth connection electrode 31.

[0080] The potential of the first wiring 26 is supplied to the first electrode 23 via the first connection electrode 28, the first conductive portion 32, and the third connection electrode 30. The potential of the second wiring 27 is supplied to the second electrode 24 via the second connection electrode 29, the second conductive portion 33, and the fourth connection electrode 31. The first connection electrode 28 protruding from the first wiring 26 toward the second wiring 27 and the second connection electrode 29 protruding from the second wiring 27 toward the first wiring 26 are arranged along the extending direction of the second wiring 27. The third connection electrode 30 electrically connected to the first electrode 23 is arranged to overlap with the first connection electrode 28, and the fourth connection electrode 31 electrically connected to the second electrode 24 is arranged to overlap with the second connection electrode 29. According to this configuration, the first conductive portion 32 arranged to overlap with the first connection electrode 28 and the third connection electrode 30 is arranged not to overlap with the second electrode 24, and the second conductive portion 33 arranged to overlap with the second connection electrode 29 and the fourth connection electrode 31 is arranged not to overlap with the first electrode 23. Therefore, even when the number of the conduction portions (the first connection electrode 28, the first conductive portion 32, and the third connection electrode 30) between the first wiring 26 and the first electrode 23 and the number of the conduction portions (the second connection electrode 29, the second conductive portion 33, and the fourth connection electrode 31) between the second wiring 27 and the second electrode 24 are increased respectively, it is possible to avoid the short circuit between the third connection electrode 30 and the second electrode 24 due to the first conductive portion 32, and it is possible to avoid the short circuit between the fourth connection electrode 31 and the first electrode 23 due to the second conductive portion 33. Through the above, it is possible to improve the connection reliability. In addition, it is preferable that the resistance distribution of the first electrode 23 and the second electrode 24 is difficult to deviate. In addition, since the first connection electrode 28 and the second connection electrode 29 are arranged to be sandwiched between the first wiring 26 and the second wiring 27, the space efficiency is good, and it is also preferable for realizing a narrow bezel.

[0081] In addition, the array substrate 11B includes: a plurality of side portions 11B1 and 11B2; a plurality of first wirings 26 extending along the plurality of side portions 11B1 and 11B2 respectively; a plurality of second wirings 27 extending along the plurality of side portions 11B1 and 11B2 respectively. A first connection electrode 28 is provided on each of the plurality of first wirings 26, and a second connection electrode 29 is provided on each of the plurality of second wirings 27 respectively. A plurality of third connection electrodes 30 and a plurality of first conductive portions 32 are each arranged to overlap with each of the plurality of first connection electrodes 28, and a plurality of fourth connection electrodes 31 and a plurality of second conductive portions 33 are each arranged to overlap with each of the plurality of second connection electrodes 29. The plurality of first connection electrodes 28 provided on the plurality of first wirings 26 are electrically connected to the plurality of third connection electrodes 30 through the plurality of first conductive portions 32 respectively. Thus, deviation is not likely to occur in the resistance distribution of the first electrode 23. The plurality of second connection electrodes 29 provided on each of the plurality of second wirings 27 are electrically connected to each of the plurality of fourth connection electrodes 31 through the plurality of second conductive portions 33. Thus, deviation is hardly likely to occur in the resistance distribution of the second electrode 24.

[0082] Furthermore, it includes: a liquid crystal layer 11C sandwiched between the array substrate 11B and the counter substrate 11A; and a sealing portion 11D interposed between the array substrate 11B and the counter substrate 11A to seal the liquid crystal layer 11C in a surrounding manner. The plurality of first wirings 26 and the plurality of second wirings 27 extend in parallel with the sealing portion 11D, and the plurality of first connection electrodes 28, the plurality of second connection electrodes 29, the plurality of third connection electrodes 30, and the plurality of fourth connection electrodes 31 are arranged to overlap with the sealing portion 11D, and the plurality of first conductive portions 32 and the plurality of second conductive portions 33 are arranged within the sealing portion 11D. When the liquid crystal layer 11C is sealed by the sealing portion 11D, the plurality of first conductive portions 32 arranged within the sealing portion 11D are electrically connected to the plurality of first connection electrodes 28 and the plurality of third connection electrodes 30 that overlap with the sealing portion 11D, and the plurality of second conductive portions 33 arranged within the sealing portion 11D are electrically connected to the plurality of second connection electrodes 29 and the plurality of fourth connection electrodes 31 that overlap with the sealing portion 11D. In this way, the installation spaces of the sealing portion 11D, the first conductive portion 32, and the second conductive portion 33 are shared. Thereby, the space efficiency is improved, which is preferable for achieving a narrow bezel.

[0083] In addition, a plurality of first connection electrodes 28 and a plurality of second connection electrodes 29 are respectively provided on the first wiring 26 and the second wiring 27, and are alternately arranged in the extending direction. In this way, the plurality of first connection electrodes 28 provided on the first wiring 26 and the plurality of second connection electrodes 29 provided on the second wiring 27 are alternately arranged in the extending direction of the second wiring 27. The plurality of third connection electrodes 30 are electrically connected to the plurality of first connection electrodes 28 via the plurality of first conductive portions 32, so that deviation is not likely to occur in the resistance distribution of the first electrode 23. The plurality of fourth connection electrodes 31 are electrically connected to the plurality of second connection electrodes 29 via the plurality of second conductive portions 33, so that deviation is not likely to occur in the resistance distribution of the second electrode 24.

[0084] In addition, the array substrate 11B and the counter substrate 11A are divided into a display region AA for displaying an image and a non-display region NAA surrounding the display region AA. The first electrode 23 and the second electrode 24 are arranged such that at least a part thereof overlaps in the display region AA. An insulating film 25 is provided on the counter substrate 11A at least between the overlapping portions of the first electrode 23 and the second electrode 24, and transmits a common potential to the first wiring 26 and a ground potential to the second wiring 27. The common potential transmitted through the first wiring 26 is supplied to the first electrode 23 via the first connection electrode 28, the first conductive portion 32, and the third connection electrode 30. Since at least a part of the first electrode 23 is arranged in the display region AA, an image can be displayed in the display region AA by using the common potential supplied to the first electrode 23. The ground potential transmitted through the second wiring 27 is supplied to the second electrode 24 via the second connection electrode 29, the second conductive portion 33, and the fourth connection electrode 31. Since at least a part of the second electrode 24, which is a ground potential, is arranged to overlap the first electrode 23 in the display region AA, the first electrode 23 can be shielded from external noise by the second electrode 24. Moreover, since the insulating film 25 is provided between the overlapping portions of the first electrode 23 and the second electrode 24, a capacitance is formed between the first electrode 23 and the second electrode 24, which are set to different potentials. Thereby, the potential variation of the first electrode 23 can be suppressed.

[0085] In addition, the first electrode 23 is disposed on the upper layer side of the second electrode 24 with the insulating film 25 therebetween. The third connection electrode 30 is located on the same layer as the second electrode 24 and is disposed so as to overlap a part of the first electrode 23. A contact hole 25A for electrically connecting the first electrode 23 and the third connection electrode 30 is provided in a portion of the insulating film 25 that overlaps the overlapping portion of the first electrode 23 and the third connection electrode 30. The fourth connection electrode 31 is located on the same layer as the second electrode 24 and is connected to the end of the second electrode 24. The third connection electrode 30 located on the same layer as the second electrode 24 is electrically connected to the first electrode 23 through the contact hole 25A of the insulating film 25. The fourth connection electrode 31 is electrically connected to the second electrode 24 by being connected to the end of the second electrode 24 on the same layer. Since both the third connection electrode 30 and the fourth connection electrode 31 are located on the same layer as the second electrode 24, the heights of the first conductive portion 32 and the second conductive portion 33 can be made the same. As a result, not only can the materials (conductive particles 11D2) of the first conductive portion 32 and the second conductive portion 33 be made common, but also high connection reliability can be obtained.

[0086] In addition, the insulating film 25 covers at least a portion of the third connection electrode 30 that does not overlap with the first conductive portion 32 and at least a portion of the fourth connection electrode 31 that does not overlap with the second conductive portion 33. In this way, at least a portion of the third connection electrode 30 that does not overlap with the first conductive portion 32 and at least a portion of the fourth connection electrode 31 that does not overlap with the second conductive portion 33 are respectively covered by the insulating film 25, thereby achieving protection.

[0087] <Second Embodiment>

[0088] By Figures 12 to 14 explaining the second embodiment. In this second embodiment, a case where the configurations of the third connection electrode 130 and the fourth connection electrode 131 are changed is shown. In addition, redundant descriptions of the same structures, operations, and effects as those in the above first embodiment are omitted.

[0089] Using Figures 12 to 14 , the configurations of the third connection electrode 130 and the fourth connection electrode 131, etc. will be described. As Figure 12 and Figure 13As shown, the third connection electrode 130 of the present embodiment has a first lower electrode portion 34 located on the same layer as the second electrode 124 and a first upper electrode portion 35 located on the same layer as the first electrode 123. The first lower electrode portion 34 is separated from the second electrode 124 on the same layer. The first lower electrode portion 34 is formed of the same transparent electrode film as the second electrode 124 and is formed of a portion different from the second electrode 124 in the transparent electrode film. Therefore, when manufacturing the opposing substrate 111A, the first lower electrode portion 34 is formed by the same process as the process of forming the second electrode 124. The first upper electrode portion 35 is connected to the end of the first electrode 123 on the same layer and is disposed overlapping the first lower electrode portion 34. The first upper electrode portion 35 is formed of the same transparent electrode film as the first electrode 123 and is formed of a portion different from the first electrode 123 in the transparent electrode film. Therefore, when manufacturing the opposing substrate 111A, the first upper electrode portion 35 is formed by the same process as the process of forming the first electrode 123. A first contact hole 25B is provided at a position in the insulating film 125 that overlaps the first lower electrode portion 34 and the first upper electrode portion 35. The first contact hole 25B is disposed near the end on the display region AA side of the first lower electrode portion 34 and the first upper electrode portion 35. The first lower electrode portion 34 and the first upper electrode portion 35 are electrically connected to each other through the first contact hole 25B. Thus, since the third connection electrode 130 is composed of the first lower electrode portion 34 and the first upper electrode portion 35 that are electrically connected through the first contact hole 25B, the wiring resistance of the common potential supplied from the first wiring 126 to the first electrode 123 can be reduced.

[0090] As Figure 12 and Figure 14As shown, the fourth connection electrode 131 has a second lower electrode portion 36 that is on the same layer as the second electrode 124 and a second upper electrode portion 37 that is on the same layer as the first electrode 123. The second lower electrode portion 36 is connected to the end of the second electrode 124 on the same layer. The second lower electrode portion 36 is formed of the same transparent electrode film as the second electrode 124 and is formed of a portion of the transparent electrode film that is different from the second electrode 124. Therefore, when manufacturing the counter substrate 111A, the second lower electrode portion 36 is formed by the same process as the process of forming the second electrode 124. The second upper electrode portion 37 is separated from the first electrode 123 on the same layer and is disposed overlapping the second lower electrode portion 36. The second upper electrode portion 37 is formed of the same transparent electrode film as the first electrode 123 and is formed of a portion of the transparent electrode film that is different from the first electrode 123. Therefore, when manufacturing the counter substrate 111A, the second upper electrode portion 37 is formed by the same process as the process of forming the first electrode 123. A second contact hole 25C is provided at a position in the insulating film 125 that overlaps the second lower electrode portion 36 and the second upper electrode portion 37. The second contact hole 25C is disposed near the end portion on the side opposite to the display region AA side (outer side) of the second lower electrode portion 36 and the second upper electrode portion 37. The second lower electrode portion 36 and the second upper electrode portion 37 are electrically connected to each other through the second contact hole 25C. In this way, the fourth connection electrode 131 is composed of the second lower electrode portion 36 and the second upper electrode portion 37 that are electrically connected through the second contact hole 25C, so that the wiring resistance of the ground potential supplied from the second wiring 127 to the second electrode 124 can be reduced.

[0091] On the counter substrate 111A, as Figures 12 to 14 shown, a lower layer wiring 38 that is on the same layer as the second electrode 124 and an upper layer wiring 39 that is on the same layer as the first electrode 123 are provided. The lower layer wiring 38 and the upper layer wiring 39 are disposed overlapping each other with the insulating film 125 therebetween. The lower layer wiring 38 and the upper layer wiring 39 are disposed overlapping the second wiring 127 of the array substrate 111B. The lower layer wiring 38 and the upper layer wiring 39 are disposed adjacent to each other on the outer side (the side opposite to the display region AA side) of the counter substrate 111A with respect to the third connection electrode 130 and the fourth connection electrode 131. The lower layer wiring 38 extends along the extending direction of the first wiring 126 and the second wiring 127 ( Figure 12 the Y-axis direction in Figure 12extends in the Y-axis direction in (), and is connected to the end on the side opposite to the display area AA side in the second upper electrode portion 37. A third contact hole 25D is provided at a position in the insulating film 125 that overlaps with the lower layer wiring 38 and the upper layer wiring 39. The lower layer wiring 38 and the upper layer wiring 39 are electrically connected through the third contact hole 25D. In this way, the lower layer wiring 38 is electrically connected to the second lower electrode portion 36, and the upper layer wiring 39 is electrically connected to the second upper electrode portion 37. Therefore, the wiring resistance of the ground potential supplied from the second wiring 127 to the second electrode 124 can be further reduced. In addition, like the first wiring 126 and the second wiring 127, four lower layer wirings 38 are provided along each of the four side portions of the opposing substrate 111A. The ends of the four lower layer wirings 38 are connected to each other, and in a plan view, they form a square frame shape (endless ring shape) to entirely surround the display area AA. The ends of the four upper layer wirings 39 are connected to each other, and in a plan view, they form a square frame shape (endless ring shape) to entirely surround the display area AA.

[0092] As described above, according to the present embodiment, the first electrode 123 is disposed on the upper layer side of the second electrode 124 with the insulating film 125 interposed therebetween. The third connection electrode 130 includes: a first lower electrode portion 34 located on the same layer as the second electrode 124, and a first upper electrode portion 35 located on the same layer as the first electrode 123, connected to the first electrode 123, and disposed overlapping the first lower electrode portion 34. The fourth connection electrode 131 includes: a second lower electrode portion 36 located on the same layer as the second electrode 124 and connected to the second electrode 124, and a second upper electrode portion 37 located on the same layer as the first electrode 123 and disposed overlapping the second lower electrode portion 36. A first contact hole 25B for electrically connecting the first lower electrode portion 34 and the first upper electrode portion 35 is provided at a position in the insulating film 125 that overlaps with the first lower electrode portion 34 and the first upper electrode portion 35. A second contact hole 25C for electrically connecting the second lower electrode portion 36 and the second upper electrode portion 37 is provided at a position in the insulating film 125 that overlaps with the second lower electrode portion 36 and the second upper electrode portion 37. The first upper electrode portion 35 connected to the first electrode 123 is electrically connected through the first lower electrode portion 34 and the first contact hole 25B of the insulating film 125 that overlap. The third connection electrode 130 is composed of the first lower electrode portion 34 and the first upper electrode portion 35 that are electrically connected through the first contact hole 25B. Therefore, the wiring resistance of the common potential supplied from the first wiring 126 to the first electrode 123 can be reduced. The second lower electrode portion 36 connected to the second electrode 124 is electrically connected through the second upper electrode portion 37 and the second contact hole 25C of the insulating film 125 that overlap. The fourth connection electrode 131 is composed of the second lower electrode portion 36 and the second upper electrode portion 37 that are electrically connected through the second contact hole 25C. Therefore, the wiring resistance of the ground potential supplied from the second wiring 127 to the second electrode 124 can be reduced.

[0093] In addition, on the opposing substrate 111A, there are provided: a lower-layer wiring 38, which is on the same layer as the second electrode 124, extends along the extending direction of the second wiring 127, and is connected to the end of the second lower-layer electrode portion 36; and an upper-layer wiring 39, which is on the same layer as the first electrode 123, extends along the extending direction, is connected to the end of the second upper-layer electrode portion 37, and is disposed overlapping the lower-layer wiring 38. At a position in the insulating film 125 where the lower-layer wiring 38 and the upper-layer wiring 39 overlap, a third contact hole 25D for conducting the lower-layer wiring 38 and the upper-layer wiring 39 is provided. The lower-layer wiring 38 and the upper-layer wiring 39, both extending along the extending direction of the second wiring 127, overlap each other and are conducted through the third contact hole 25D in the insulating film 125. The lower-layer wiring 38 is conducted with the second lower-layer electrode portion 36, and the upper-layer wiring 39 is conducted with the second upper-layer electrode portion 37. Therefore, the wiring resistance of the ground potential supplied from the second wiring 127 to the second electrode 124 can be further reduced.

[0094] <Third Embodiment>

[0095] By Figures 15 to 17 The third embodiment will be described. In this third embodiment, a case where an overlapping wiring 41 and the like are added to the above-described second embodiment is shown. In addition, the description of the same structures, operations, and effects as those in the above-described second embodiment will be omitted.

[0096] Use Figures 15 to 17 The configuration of the opposing substrate 211 will be described. As Figures 15 to 17 shown, on the opposing substrate 211, a lower-layer insulating film 40 on the lower layer side of the second electrode 224 and an overlapping wiring 41 on the lower layer side of the lower-layer insulating film 40 are provided. The film thickness of the lower-layer insulating film 40 is larger than that of the insulating film 225 disposed on the upper layer side. The lower-layer insulating film 40 is provided at least over the entire area of the non-display area NAA. The lower-layer insulating film 40 may be provided in a planar shape over the entire areas of the display area AA and the non-display area NAA.

[0097] The overlapping wiring 41 extends along the extending directions of the first wiring 226 and the second wiring 227. Specifically, the overlapping wiring 41 extends in the non-display region NAA of the relative substrate 21A so as to surround the display region AA over the entire circumference, and is in a square frame shape (endless loop shape) as a whole when viewed from above. The overlapping wiring 41 extends in parallel with the sealing portion 211D and is disposed so as to overlap the sealing portion 211D. The overlapping wiring 41 is disposed so as to overlap the third connection electrode 230 (the first lower electrode portion 234 and the first upper electrode portion 235) and the fourth connection electrode 231 (the second lower electrode portion 236 and the second upper electrode portion 237). Moreover, the overlapping wiring 41 is also disposed so as to overlap the lower wiring 239 and the upper wiring 240. The overlapping wiring 41 is formed by patterning a metal film made of a metal material by a known photolithography method. Although the overlapping wiring 41 made of a metal film has light-shielding properties, since it is disposed in the non-display region NAA, it is possible to avoid adverse effects on the image displayed in the display region AA.

[0098] A fourth contact hole 40A is provided at a position in the lower insulating film 40 that overlaps both the overlapping wiring 41 and the first lower electrode portion 234 constituting the third connection electrode 230. The overlapping wiring 41 and the first lower electrode portion 234 that overlap each other are electrically connected to each other through the fourth contact hole 40A. Thus, since the overlapping wiring 41 is electrically connected to the third connection electrode 230, it is set to the same common potential as the first wiring 226, the first connection electrode 228, and the third connection electrode 230. Since the overlapping wiring 41 is made of a metal film and extends over the entire circumference in the non-display region NAA, it is preferable in terms of reducing the wiring resistance of the common potential supplied from the first wiring 226 to the first electrode 223. In addition, although the overlapping wiring 41 is also in a positional relationship of overlapping with the second lower electrode portion 236 constituting the fourth connection electrode 231, a lower insulating film 40 thicker than the insulating film 225 is interposed between the overlapping wiring 41 and the second lower electrode portion 236. Here, when setting the film thickness of the insulating film 225, it is necessary to make the first electrode 223 and the second electrode 224 sufficiently thin so that a predetermined electrostatic capacitance is formed between the first electrode 223 and the second electrode 224. On the other hand, when setting the film thickness of the lower insulating film 40, it is not necessary to consider forming an electrostatic capacitance between the overlapping wiring 41 and the second lower electrode portion 236, and the film thickness of the lower insulating film 40 can be made sufficiently large. Therefore, it is difficult for the second conductive portion 233 to pierce the lower insulating film 40 and cause a short circuit between the second lower electrode portion 236 of the fourth connection electrode 231 and the overlapping wiring 41.

[0099] As described above, according to the present embodiment, a lower insulating film 40 and overlapping wirings 41 are provided on the opposing substrate 211A. The lower insulating film 40 is located on the lower layer side of the second electrode 224 and has a film thickness greater than that of the insulating film 225. The overlapping wirings 41 are located on the lower layer side of the lower insulating film 40, extend along the extending direction of the second wiring 227, and are arranged to overlap with the third connection electrode 230 and the fourth connection electrode 231. At the position in the lower insulating film 40 that overlaps with the overlapping wirings 41 and the first lower electrode portion 234, a fourth contact hole 40A for conducting the overlapping wirings 41 and the first lower electrode portion 234 is provided. The overlapping wirings 41 extending along the extending direction of the second wiring 227 are arranged to overlap with the third connection electrode 230 and the fourth connection electrode 231, and are conducted to the first lower electrode portion 234 of the third connection electrode 230 through the fourth contact hole 40A of the insulating film 225. The wiring resistance of the common potential supplied from the first wiring 226 to the first electrode 223 can be further reduced through the overlapping wirings 41. In addition, since the lower insulating film 40 is thicker than the insulating film 225, it is difficult for the second conductive portion 233 to pierce the lower insulating film 40 and cause a short circuit between the second lower electrode portion 236 of the fourth connection electrode 231 and the overlapping wirings 41.

[0100] <Fourth Embodiment>

[0101] By Figures 18 to 22 The fourth embodiment will be described. In this fourth embodiment, a case where a third wiring 42, a third electrode 46, etc. are added to the above-described second embodiment is shown. In addition, redundant descriptions of the same structures, operations, and effects as those of the above-described second embodiment are omitted.

[0102] Use Figure 18 And Figure 20 The configuration of the non-display area NAA of the array substrate 311B will be described. As Figure 18As shown, a third wiring 42 is provided on a non-display area NAA of the array substrate 311B in the present embodiment. The third wiring 42 is disposed at a position where the second wiring 327 is sandwiched between it and the first wiring 326, and extends in parallel with the first wiring 326 and the second wiring 327. The third wiring 42 is disposed closer to the outer end of the array substrate 311B (the side away from the display area AA) with respect to either the first wiring 326 or the second wiring 327. The third wiring 42 is disposed at a position spaced apart from the second wiring 327. The interval between the third wiring 42 and the second wiring 327 is substantially constant throughout the entire length, and its size is smaller than the interval between the first wiring 326 and the second wiring 327. The third wiring 42 can supply a touch panel drive signal potential to a third electrode described later. The third wiring 42 is provided with four in the same manner as the first wiring 326 and the second wiring 327, extending along the X-axis direction and the Y-axis direction (the four side portions of the array substrate 311B). The ends of the four third wirings 42 are connected to each other, and in a manner of surrounding the display area AA as a whole, it is in a square frame shape (endless loop shape) in a plan view. The four third wirings 42 are parallel to the sealing portion 311D. The third wiring 42 is disposed at a position not overlapping with the sealing portion 311D.

[0103] As Figure 18 shown, a fifth connection electrode 43 protruding toward the first wiring 326 and the second wiring 327 side (the side closer to the display area AA) is electrically connected to the third wiring 42. The fifth connection electrode 43 is formed of the same metal film as the third wiring 42 and is connected to the third wiring 42. Therefore, when manufacturing the array substrate 311B, the fifth connection electrode 43 is formed by the same process as the process of forming the third wiring 42. The fifth connection electrode 43 extends from the third wiring 42 in a direction intersecting with the extending direction of the second wiring 327 ( Figure 18 the Y-axis direction in this case) ( Figure 18 the X-axis direction in this case). A plurality of the fifth connection electrodes 43 are arranged at intervals in the extending direction of the second wiring 327. The arrangement interval of the plurality of fifth connection electrodes 43 is larger than the sum of the widths of the first connection electrode 328 and the second connection electrode 329. The plurality of fifth connection electrodes 43, together with the plurality of first connection electrodes 328 and the plurality of second connection electrodes 329, are arranged in a row. Therefore, the plurality of fifth connection electrodes 43, together with the plurality of first connection electrodes 328 and the plurality of second connection electrodes 329, are arranged in a manner overlapping with the sealing portion 311D in a plan view. The fifth connection electrode 43 is disposed at a position sandwiched between the first connection electrode 328 and the second connection electrode 329. That is, in the non-display area NAA of the array substrate 311B, the plurality of first connection electrodes 328, the plurality of second connection electrodes 329, and the plurality of fifth connection electrodes 43 are alternately arranged and configured in a specified order (the order of the first connection electrode 328, the fifth connection electrode 43, and the second connection electrode 329).

[0104] As shown Figure 20 in the figure, the third wiring 42 and the fifth connection electrode 43 are arranged at a position on the upper layer side relative to the first wiring 326 and the second wiring 327. A first insulating film 44 is provided on the array substrate 311B on the lower layer side of the first wiring 326 and the second wiring 327, and a second insulating film 45 is arranged on the upper layer side of the first wiring 326 and the second wiring 327 on the lower layer side of the third wiring 42. The base end side portion of the fifth connection electrode 43 connected to the third wiring 42 crosses the second wiring 327. The second insulating film 45 is provided at least at a position between the overlapping fifth connection electrode 43 and the second wiring 327. Thus, the fifth connection electrode 43 and the second wiring 327 are kept in an insulated state from each other.

[0105] Next, the structure of the counter substrate 311 will be described using Figure 19 and Figure 20 As shown Figure 19 and Figure 20 in the figure, a third electrode 46 is provided on the counter substrate 31A of the present embodiment. The third electrode 46 constitutes at least a part of the electrode for the touch panel. The third electrode 46 is provided in a whole-surface shape at least in the display area AA, and is arranged to overlap with the first electrode 323 and the second electrode 324 in a plan view. The third electrode 46, like the first electrode 323 and the second electrode 324, has a formation range spanning the display area AA and the non-display area NAA. Each outer peripheral end portion of the third electrode 46 is located on the inner peripheral side (display area AA side) relative to the sealing portion 311D and does not overlap with the sealing portion 311D. The third electrode 46, like the first electrode 323 and the second electrode 324, is formed by patterning a transparent electrode film (lower layer transparent electrode film) made of a transparent electrode material such as ITO (Indium Tin Oxide) using a known photolithography method. A touch panel drive signal potential is supplied to the third electrode 46 through the above-mentioned third wiring 42. The third electrode 46 is arranged at a position on the lower layer side relative to the second electrode 324. On the counter substrate 311A, a third insulating film 47 located on the upper layer side of the third electrode 46 is provided on the lower layer side of the second electrode 324. The third electrode 46 is located on the lower layer side of the third insulating film 47. The second electrode 324 is located on the upper layer side of the third insulating film 47.

[0106] Next, the structure of the non-display area NAA of the counter substrate 311A will be described using Figure 19 and Figure 20 As shown Figure 19 and Figure 20As shown, in the non-display area NAA of the opposite substrate 31A in this embodiment, a sixth connection electrode 48 is provided which is electrically connected to the third electrode 46. The sixth connection electrode 48 extends from the end of the third electrode 46 along the direction along the end of the third electrode 46 ( Figure 19 The direction of intersection ( Figure 19 The sixth connecting electrode 48 is arranged in a plurality of intervals along the direction of the end of the third electrode 46 (the X-axis direction or the Y-axis direction). The sixth connecting electrode 48 is arranged throughout the entire circumference of the outer peripheral end formed by the four ends of the third electrode 46. In other words, the sixth connecting electrode 48 is provided in plurality at each of the four ends constituting the outer peripheral end of the third electrode 46. Figure 19 As shown, the arrangement interval of the plurality of sixth connection electrodes 48 is larger than the sum of the width of the third connection electrode 330 and the width of the fourth connection electrode 331. The plurality of sixth connection electrodes 48 are arranged in a row together with the plurality of third connection electrodes 330 and the plurality of fourth connection electrodes 331. Therefore, the plurality of sixth connection electrodes 48 are arranged so as to overlap with the sealing portion 311D when viewed from above together with the plurality of third connection electrodes 330 and the plurality of fourth connection electrodes 331. The sixth connection electrode 48 is arranged at a position sandwiched between the third connection electrode 330 and the fourth connection electrode 331. That is, in the non-display area NAA relative to the substrate 31A, the plurality of third connection electrodes 330, the plurality of fourth connection electrodes 331 and the plurality of sixth connection electrodes 48 are alternately and repeatedly arranged in a prescribed order (the order of the third connection electrode 330, the sixth connection electrode 48 and the fourth connection electrode 331).

[0107] Next, use Figure 20 The relationship between the fifth connection electrode 43 and the sixth connection electrode 48 will be described. Figure 20 As shown, the sixth connecting electrode 48 is arranged to overlap with the fifth connecting electrode 43. That is, the sixth connecting electrode 48 is arranged relative to the fifth connecting electrode 43 with a gap in the Z-axis direction. The sixth connecting electrode 48 is located on the lower side of the third insulating film 47, that is, it is located in the same layer as the third electrode 46. The sixth connecting electrode 48 is composed of the same transparent electrode film as the third electrode 46, and is composed of a portion of the transparent electrode film that is different from the third electrode 46. Therefore, when manufacturing the relative substrate 31A, the sixth connecting electrode 48 is formed in the same process as the process of forming the third electrode 46. The end of the sixth connecting electrode 48 on the display area AA side is connected to the end of the third electrode 46 on the same layer, thereby achieving conduction between the sixth connecting electrode 48 and the third electrode 46.

[0108] like Figure 20As shown, the plurality of conductive particles 311D2 included in the sealing portion 311D include conductive particles that form a positional relationship overlapping with the fifth connection electrode 43 and the sixth connection electrode 48. The conductive particles 311D2 in the positional relationship overlapping with the fifth connection electrode 43 and the sixth connection electrode 48 constitute the third conductive portion 49 that contacts the fifth connection electrode 43 and the sixth connection electrode 48. The conduction between the fifth connection electrode 43 and the sixth connection electrode 48 is achieved through the third conductive portion 49. In this way, the touch panel drive signal potential is supplied to the third electrode 46 from the plurality of fifth connection electrodes 43 respectively connected to the plurality of (four) third wirings 42 surrounding the third electrode 46 throughout the circumference, via the plurality of third conductive portions 49 and the plurality of sixth connection electrodes 48. Therefore, it is difficult for the resistance distribution of the third electrode 46 to deviate. Thus, even when a potential change occurs in the third electrode 46 due to noise input from the sub liquid crystal panel 13 or the like, the potential of the third electrode 46 can be quickly restored to the original touch panel drive signal potential of the touch panel. Moreover, the third conductive portion 49 disposed overlapping the fifth connection electrode 43 and the sixth connection electrode 48 is arranged so as not to overlap with the first electrode 323 and the second electrode 324. Therefore, even if the number of the conduction portions (the fifth connection electrode 43, the third conductive portion 49, and the sixth connection electrode 48) between the third wiring 42 and the third electrode 46 increases as described above, it is possible to avoid the short circuit between the sixth connection electrode 48 and the first electrode 323 or the short circuit between the sixth connection electrode 48 and the second electrode 324 due to the third conductive portion 49. Through the above, the improvement of the connection reliability can be achieved. In addition, the end portion of the sixth connection electrode 48 on the side opposite to the display region AA side does not overlap with the sealing portion 311D, but is covered by the third insulating film 47. In this way, the end portion of the sixth connection electrode 48 located outside the sealing portion 311D can be protected by the third insulating film 47.

[0109] Use Figure 21 and Figure 22 The configurations of the third connection electrode 330 and the fourth connection electrode 331 will be described. As Figure 21 and Figure 22As shown, the third connecting electrode 330 and the fourth connecting electrode 331 of this embodiment are both located on the lower side of the third insulating film 47, that is, on the same layer as the third electrode 46 and the sixth connecting electrode 48. The third connecting electrode 330 and the fourth connecting electrode 331 are separated from the third electrode 46 and the sixth connecting electrode 48 on the same layer. The third connecting electrode 330 and the fourth connecting electrode 331 are composed of the same transparent electrode film as the third electrode 46, and are composed of a portion of the transparent electrode film that is different from the third electrode 46 and the sixth connecting electrode 48. Therefore, when manufacturing the counter substrate 31A, the third connecting electrode 330 and the fourth connecting electrode 331 are formed in the same process as the process for forming the third electrode 46 and the sixth connecting electrode 48.

[0110] like Figure 21 As shown, the majority of the fourth connection electrode 331 does not overlap with the second electrode 324, but a portion thereof overlaps with the second electrode 324 via the third insulating film 47. Specifically, the end portion of the fourth connection electrode 331 on the display area AA side overlaps with the end portion of the second electrode 324, with the third insulating film 47 interposed therebetween. A fifth contact hole 47A is provided in the portion of the third insulating film 47 that overlaps the overlapping portion of the second electrode 324 and the fourth connection electrode 331, providing electrical connection between the second electrode 324 and the fourth connection electrode 331. The end portion of the fourth connection electrode 331 on the display area AA side is electrically connected to the end portion of the second electrode 324 via the fifth contact hole 47A in the third insulating film 47.

[0111] like Figure 22 As shown, most of the third connecting electrode 330 does not overlap with the first electrode 323, but a portion thereof overlaps with the first electrode 323 via the insulating film 325 and the third insulating film 47. Specifically, the end portion of the third connecting electrode 330 on the display area AA side overlaps with the end portion of the first electrode 323, with the insulating film 325 and the third insulating film 47 interposed therebetween. A sixth contact hole 47B is provided in the portion of the insulating film 325 and the third insulating film 47 that overlaps with the overlapping portion of the first electrode 323 and the third connecting electrode 330, thereby electrically connecting the first electrode 323 and the third connecting electrode 330. The sixth contact hole 47B is in communication with the insulating film 325 and the third insulating film 47. The end portion of the third connecting electrode 330 on the display area AA side and the end portion of the first electrode 323 are electrically connected via the sixth contact hole 47B in the insulating film 325 and the third insulating film 47.

[0112] As mentioned above, Figures 20 to 22As shown, the third connection electrode 330, the fourth connection electrode 331, and the sixth connection electrode 48 are all on the same layer as the third electrode 46. The third connection electrode 330, the fourth connection electrode 331, and the sixth connection electrode 48 are on the same layer as each other. Therefore, the Z-axis direction intervals between the mutually opposing first connection electrode 328 and the third connection electrode 330, between the mutually opposing second connection electrode 329 and the fourth connection electrode 331, and between the mutually opposing fifth connection electrode 43 and the sixth connection electrode 48 are substantially the same. Thus, it is possible to make the first conductive portion 332 between the first connection electrode 328 and the third connection electrode 330, the second conductive portion 333 between the second connection electrode 329 and the fourth connection electrode 331, and the third conductive portion 49 between the fifth connection electrode 43 and the sixth connection electrode 48 have substantially the same height. The first conductive portion 332, the second conductive portion 333, and the third conductive portion 49 are, as described, part of the plurality of conductive particles 311D2 included in the sealing portion 311D. Therefore, it is only necessary to make the sealing portion 311D contain conductive particles 311D2 of one particle size, which can achieve a reduction in material costs and also improve connection reliability.

[0113] As described above, according to the present embodiment, it includes: a third wiring 42 provided on the array substrate 311B, arranged at a position where the second wiring 327 is interposed between the first wiring 326 or the first wiring 326 is interposed between the second wiring 327, and extending in parallel with the first wiring 326 and the second wiring 327; a fifth connection electrode 43 protruding from the third wiring 42 toward the first wiring 326 and the second wiring 327 side, and arranged at intervals in the extending direction from the first connection electrode 328 and the second connection electrode 329 respectively; a third electrode 46 provided on the counter substrate 311A; a sixth connection electrode 48 provided on the counter substrate 311A, electrically connected to the third electrode 46, arranged overlapping the fifth connection electrode 43, and arranged at intervals in the extending direction from the third connection electrode 330 and the fourth connection electrode 331 respectively; and a third conductive portion 49 interposed between the array substrate 311B and the counter substrate 311A, arranged overlapping the fifth connection electrode 43 and the sixth connection electrode 48, and in contact with the fifth connection electrode 43 and the sixth connection electrode 48. The potential of the third wiring 42 is supplied to the third electrode 46 via the fifth connection electrode 43, the third conductive portion 49, and the sixth connection electrode 48. The fifth connection electrode 43 is arranged at intervals in the extending direction of the second wiring 327 together with the first connection electrode 328 and the second connection electrode 329, and the sixth connection electrode 48 is arranged at intervals in the extending direction of the second wiring 327 together with the third connection electrode 330 and the fourth connection electrode 331. According to this configuration, the first conductive portion 332 arranged overlapping the first connection electrode 328 and the third connection electrode 330 is arranged not overlapping the second electrode 324 and the third electrode 46, the second conductive portion 333 arranged overlapping the second connection electrode 329 and the fourth connection electrode 331 is arranged not overlapping the first electrode 323 and the third electrode 46, and the third conductive portion 49 arranged overlapping the fifth connection electrode 43 and the sixth connection electrode 48 is arranged not overlapping the first electrode 323 and the second electrode 324.Therefore, even when the number of the connection parts (the first connection electrode 328, the first conductive part 332, and the third connection electrode 330) between the first wiring 326 and the first electrode 323, the number of the connection parts (the second connection electrode 329, the second conductive part 333, and the fourth connection electrode 331) between the second wiring 327 and the second electrode 324, and the number of the connection parts (the fifth connection electrode 43, the third conductive part 49, and the sixth connection electrode 48) between the third wiring 42 and the third electrode 46 are respectively increased, it is possible to avoid the short circuit between the third connection electrode 330 and the second electrode 324 or the third electrode 46 due to the first conductive part 332, it is possible to avoid the short circuit between the fourth connection electrode 331 and the first electrode 323 or the third electrode 46 due to the second conductive part 333, and it is possible to avoid the short circuit between the sixth connection electrode 48 and the first electrode 323 or the second electrode 324 due to the third conductive part 49. Through the above, it is possible to improve the connection reliability. In addition, it is preferable in terms of making it difficult to cause deviation in the resistance distribution of the first electrode 323, the second electrode 324, and the third electrode 46.

[0114] <Fifth Embodiment>

[0115] By Figures 23 to 31 explaining the fifth embodiment. In this fifth embodiment, a case where the configuration of the sub liquid crystal panel (liquid crystal panel, electronic device) 413 is changed is shown. In addition, redundant descriptions of the same structures, operations, and effects as those in the first embodiment described above are omitted.

[0116] As Figure 23 shown, the sub liquid crystal panel 413 of the present embodiment is square as a whole, similarly to the liquid crystal panel 11 (refer to Figure 2 ). The central side portion of the main surface of the sub liquid crystal panel 413 is an active region 413AA. The active region 413AA is arranged to overlap with the display region AA of the liquid crystal panel 11. The outer peripheral side portion in a frame shape surrounding the active region 413AA in the screen of the sub liquid crystal panel 413 is set as a non - active region 413NAA. The non - active region 413NAA is in a square frame shape. In addition, Figure 23 the range surrounded by the single - dotted line in Figure 1 is the active region 413AA. In addition, the sub liquid crystal panel 413 is arranged on the front side overlapping the liquid crystal panel 11, with the liquid crystal panel 11 interposed between it and the backlight device 12 (refer to

[0117] As Figure 23As shown, the sub liquid crystal panel 413 has a pair of substrates 50 and 51 made of glass that are substantially transparent and have excellent light transmittance. The pair of substrates 50 and 51 includes a first substrate 50 disposed on the back side and a second substrate 51 disposed on the front side. The planar shapes of the first substrate 50 and the second substrate 51 are both square, and each has a pair of side portions 50A and 51A along the X-axis direction and a pair of side portions 50B and 51B along the Y-axis direction (refer to Figure 26 and Figure 27 ). Among them, the first substrate 50 is larger than the second substrate 51, and a part of it protrudes laterally with respect to the second substrate 51. A flexible substrate (signal transmission component) 52 is mounted on the protruding portion 50C of the first substrate 50. The flexible substrate 52 is configured such that a plurality of wiring patterns are formed on a substrate having insulation and flexibility. One end side of the flexible substrate 52 is connected to the first substrate 50, and the other end side is connected to an external control substrate (signal supply source). Various signals supplied from the control substrate are transmitted to the sub liquid crystal panel 413 via the flexible substrate 52.

[0118] Next, Figure 24 is used to illustrate the schematic cross-sectional structure of the sub liquid crystal panel 413. As Figure 24 shown, the pair of substrates 50 and 51 are disposed opposite to each other with a space therebetween in the normal direction of the main surfaces of the respective substrates 50 and 51, that is, in the Z-axis direction. At least a liquid crystal layer 53 and a sealing portion 54 that encapsulates (seals) the liquid crystal layer 53 are provided between the pair of substrates 50 and 51. The liquid crystal layer 53 contains liquid crystal molecules, which are substances whose optical properties change with the application of an electric field. The sealing portion 54 is disposed near the outer peripheral end portion of the non-active region 413NAA of the two substrates 50 and 51 and is provided in a form extending over the entire circumference of the outer peripheral end portion. The sealing portion 54 is in the shape of a square frame (endless ring) when viewed from above as a whole and surrounds the liquid crystal layer 54 (active region 413AA) over the entire circumference. The sealing portion 54 maintains a spacing (cell gap) of the thickness of the liquid crystal layer 53 at the outer peripheral end portions of the two substrates 50 and 51.

[0119] The sub - liquid crystal panel 413 has a modulation pattern that converts linearly polarized light emitted from the display area AA of the liquid crystal panel 11 into circularly polarized light. The modulation pattern is provided in the active area 413AA of the sub - liquid crystal panel 413. The sub - liquid crystal panel 413 functions as a modulator through the modulation pattern. Specifically, the sub - liquid crystal panel 413 applies a prescribed voltage to the liquid crystal layer 53 through the modulation pattern, thereby enabling control of the orientation state of liquid crystal molecules and the polarization state of light passing through the liquid crystal layer 53 according to the voltage value. For example, by driving the modulation pattern of the sub - liquid crystal panel 413 in synchronization with the liquid crystal panel 11 that alternately displays right - eye images and left - eye images, the polarization state of the light transmitted through the sub - liquid crystal panel 413 can be switched between right - circularly polarized light and left - circularly polarized light. The user can visually recognize a 3D image by visually recognizing the light transmitted through the sub - liquid crystal panel 413 while wearing circularly polarized glasses equipped with a circularly polarized film with reversed left - and - right rotation directions.

[0120] As Figures 25 to 27 shown, the modulation pattern includes segment electrodes (fourth electrodes) 55 provided on the first substrate 50 and a first electrode 56 provided on the second substrate 51. As Figure 25 and Figure 27 shown, the segment electrodes 55 extend along the X - axis direction, forming a band - shaped (elongated square) with a substantially constant width. The segment electrodes 55 are arranged at intervals along the Y - axis direction in the active area 413AA of the first substrate 50. In Figure 25 , an example of the arrangement of four segment electrodes 55 is illustrated, but the specific number of segment electrodes 55 provided can be appropriately changed in addition to four. The segment electrodes 55 are formed by patterning a transparent electrode film made of a transparent electrode material such as ITO (Indium Tin Oxide) using a known photolithography method. A prescribed potential is supplied to each of the plurality of segment electrodes 55 through the flexible substrate 52.

[0121] As Figure 26 and Figure 27 shown, the first electrode 56 is provided in a planar shape in the active area 413AA of the second substrate 51 and faces all the segment electrodes 55 with the liquid crystal layer 53 interposed therebetween. A common potential (reference potential) is supplied to the first electrode 56 through the flexible substrate 52. The common potential is constant at 0V, for example. In addition, the common potential can be a potential other than 0V, and in this case, the polarity can be reversed at a predetermined period. The first electrode 56, like the segment electrodes 55, is formed by patterning a transparent electrode film made of a transparent electrode material such as ITO (Indium Tin Oxide) using a known photolithography method. Thus, in the active area 413AA of the sub - liquid crystal panel 413, the light transmittance is kept high, and the light passing through the display area AA of the liquid crystal panel 11 can pass through with extremely low loss.

[0122] The modulation pattern of the sub liquid crystal panel 413 is driven based on the signal supplied by the flexible substrate 52. When a potential different from the common potential is supplied to the segment electrode 55, a potential difference is generated between the segment electrode 55 and the first electrode 56. By applying an electric field based on this potential difference to the liquid crystal layer 53, the orientation state of the liquid crystal molecules changes. The polarization state of the light transmitted through the liquid crystal layer 53 changes according to the orientation state of the liquid crystal molecules. In this way, the polarization state of the light transmitted through the liquid crystal layer 53 can be controlled based on the signal supplied to the segment electrode 55. In addition, the signals supplied to the plurality of segment electrodes 55 can be arbitrarily set. For example, in the active region 413AA of the first substrate 50, different signals can be supplied to the odd-numbered segment electrodes 55 and the even-numbered segment electrodes 55 counted from one end in the Y-axis direction. In this case, in the display region AA of the liquid crystal panel 11, for example, a right-eye image is displayed on the pixels overlapping with the odd-numbered segment electrodes 55, and a left-eye image is displayed on the pixels overlapping with the even-numbered segment electrodes 55. In this way, the light for displaying the right-eye image changes its polarization state when passing through the liquid crystal layer 53 based on the signal supplied to the odd-numbered segment electrodes 55 (the signal for the right-eye image), and the light for displaying the left-eye image changes its polarization state when passing through the liquid crystal layer 53 based on the signal supplied to the even-numbered segment electrodes 55 (the signal for the left-eye image). A user wearing circularly polarized glasses can visually recognize a 3D image by observing the light transmitted through the sub liquid crystal panel 413 whose polarization state is controlled as described above. In addition to this, for example, the same signal can be supplied to all the segment electrodes 55 at the same timing. Specifically, first, in the display region AA of the liquid crystal panel 11, all pixels display a right-eye image at a certain timing, and all pixels display a left-eye image at other timings. At the timing when all the pixels located in the display region AA of the liquid crystal panel 11 display a right-eye image, a signal for the right-eye image is supplied to all the segment electrodes 55, and at the timing when all the pixels located in the display region AA of the liquid crystal panel 11 display a left-eye image, a left-eye signal is supplied to all the segment electrodes 55. In this way, the light for displaying the right-eye image changes its polarization state when passing through the liquid crystal layer 53 based on the signal for the right-eye image supplied to all the segment electrodes 55, and the light for displaying the left-eye image changes its polarization state when passing through the liquid crystal layer 53 based on the signal for the left-eye image supplied to all the segment electrodes 55. A user wearing circularly polarized glasses can visually recognize a 3D image by observing the light transmitted through the sub liquid crystal panel 413 whose polarization state is controlled as described above.

[0123] As described above, since the segment electrodes 55 provided in the sub-liquid crystal panel 413 are input at high speed in synchronization with the display of the liquid crystal panel 11, a large amount of noise is input to the first electrode 56. Due to this noise, the potential of the first electrode 56 on the second substrate 51 may change. If the potential of the first electrode 56 changes, the potential difference between the segment electrodes 55 may not be able to properly control the polarization state of the light passing through the liquid crystal layer 53. As a result, there will be a problem of deterioration of the display quality.

[0124] Therefore, as Figure 27 shown, in the second substrate 51 of the present embodiment, in order to suppress the potential change of the first electrode 56 caused by noise, a second electrode (capacitance electrode) 57 is provided. The second electrode 57 is provided in a planar shape at least on the active region 413AA and is arranged to overlap the first electrode 56 in a plan view. The second electrode 57, like the segment electrodes 55 and the first electrode 56, is formed by patterning a transparent electrode film made of a transparent electrode material such as ITO (Indium Tin Oxide) by a known photolithography method. A ground potential (constant at 0V, for example) is supplied to the second electrode 57. On the second substrate 51, an insulating film 58 is provided in the Z-axis direction between the first electrode 56 and the second electrode 57. Therefore, a capacitance is formed between the first electrode 56 and the second electrode 57. In this way, even if noise is generated due to the high-speed input of the signal to the segment electrodes 55, it is difficult for the potential of the first electrode 56 to change due to this noise. As a result, the potential difference generated between the first electrode 56 and the segment electrodes 55 is stabilized, and the polarization state of the light passing through the liquid crystal layer 53 can be properly controlled. As a result, excellent display quality can be obtained. The first electrode 56 is located on the upper layer side of the insulating film 58 (the liquid crystal layer 53 side, the side closer to the first substrate 50). That is, the first electrode 56 is arranged at a position on the upper layer side than the second electrode 57 with the insulating film 58 interposed therebetween. Therefore, it is possible to prevent the electric field generated between the first electrode 56 and the segment electrodes 55 from being shielded by the second electrode 57.

[0125] Next, the structure of the non-active region 413NAA of the first substrate 50 will be described using Figure 25 and Figure 28 As Figure 25As shown, in the non-active region 413NAA of the first substrate 50, a first wiring 59 for supplying a common potential to the first electrode 56 and a second wiring 60 for supplying a ground potential to the second electrode 57 are provided. The first wiring 59 and the second wiring 60 are formed by patterning a metal film by a known photolithography method. The first wiring 59 and the second wiring 60 may be composed of the same metal film or different metal films. The first wiring 59 and the second wiring 60 are provided in a portion of the non-active region 413NAA of the first substrate 50 that overlaps with the second substrate 51. The first wiring 59 and the second wiring 60 are located in the non-active region 413NAA of the first substrate 50, between the active region 413AA and the side portions (ends) 50A, 50B of the first substrate 50. The first wiring 59 and the second wiring 60 are arranged at intervals and extend in parallel with each other. Four of each of the first wiring 59 and the second wiring 60 are provided so as to extend along the four side portions 50A, 50B of the first substrate 50, respectively. Among the four of each of the first wiring 59 and the second wiring 60, there are two of each of the first wiring 59 and the second wiring 60 extending in the X-axis direction and two of each of the first wiring 59 and the second wiring 60 extending in the Y-axis direction. The ends of the four first wirings 59 are connected to each other to form a square frame shape (endless ring shape) in a top view so as to surround the active region 413AA as a whole. The ends of the four second wirings 60 are connected to each other to form a square frame shape (endless ring shape) in a top view so as to surround the active region 413AA as a whole. A plurality of segment electrodes 55 are surrounded by the four first wirings 59 and also by the four second wirings 60. It can be said that the four of each of the first wiring 59 and the second wiring 60 are parallel to the sealing portion 54. The first wiring 59 is arranged on the side closer to the active region 413AA (segment electrode 55) (inner peripheral side) with respect to the second wiring 60. The second wiring 60 is arranged on the side farther from the active region 413AA (outer peripheral side) with respect to the first wiring 59.

[0126] As Figure 28 shown, the first wiring 59 and the second wiring 60 are arranged at positions that do not overlap with the sealing portion 54. In Figure 28In [the figure], the sealing portion 54 is illustrated by a double-dashed line. The first wiring 59 and the second wiring 60 are arranged with an interval greater than the width of the sealing portion 54. The interval between the first wiring 59 and the second wiring 60 is almost constant throughout the entire length. The first wiring 59 is arranged at an interval with respect to the sealing portion 54 on the side closer to the active region 413AA. The second wiring 60 is arranged at an interval with respect to the sealing portion 54 on the side farther from the active region 413AA (the side closer to the side portions 50A and 50B of the first substrate 50). The first connection electrode 61 protruding toward the second wiring 60 side (the side farther from the active region 413AA) is electrically connected to the first wiring 59. The first connection electrode 61 is formed of the same metal film as the first wiring 59 and is connected to the first wiring 59. Therefore, when manufacturing the first substrate 50, the first connection electrode 61 is formed by the same process as that for forming the first wiring 59. The first connection electrode 61 extends from the first wiring 59 in a direction crossing the extending direction of the first wiring 59 (the Y-axis direction in Figure 28 ). In Figure 28 , it is the X-axis direction). A plurality of the first connection electrodes 61 are arranged at intervals in the extending direction of the first wiring 59. The arrangement interval of the plurality of the first connection electrodes 61 is greater than the width of the second connection electrode 62. The second connection electrode 62 protruding toward the first wiring 59 side (the side closer to the active region 413AA) is electrically connected to the second wiring 60. Thus, since the first connection electrode 61 and the second connection electrode 62 are arranged sandwiching the first wiring 59 and the second wiring 60, the space efficiency is good, which is preferable for achieving a narrow bezel of the sub liquid crystal panel 413. The second connection electrode 62 is formed of the same metal film as the second wiring 60 and is connected to the second wiring 60. Therefore, when manufacturing the first substrate 50, the second connection electrode 62 is formed by the same process as that for forming the second wiring 60. The second connection electrode 62 extends from the second wiring 60 in a direction crossing the extending direction of the second wiring 60. A plurality of the second connection electrodes 62 are arranged at intervals in the extending direction of the second wiring 60. The arrangement interval of the plurality of the second connection electrodes 62 is greater than the width of the first connection electrode 61. The first connection electrode 61 and the second connection electrode 62 are arranged in the region (space) sandwiching the first wiring 59 and the second wiring 60. The first connection electrode 61 and the second connection electrode 62 are arranged in the extending direction of the first wiring 59 and the second wiring 60. A plurality of the first connection electrodes 61 and a plurality of the second connection electrodes 62 are arranged one by one alternately in the extending direction of the first wiring 59 and the second wiring 60. A plurality of the first connection electrodes 61 and a plurality of the second connection electrodes 62 are arranged so as to overlap the sealing portion 54 in a top view.

[0127] In addition, as Figure 25As shown, in the protruding portion 50C that does not overlap with the second substrate 51 in the non-active region 413NAA of the first substrate 50, lead-out wirings 59A and 60A respectively led out from the first wiring 59 and the second wiring 60 are provided. These at least a pair of lead-out wirings 59A and 60A are wired so as to reach the mounting region of the flexible substrate 52 and are connected to at least a pair of terminal portions provided in this mounting region. A common potential and a ground potential are supplied to these terminal portions through the flexible substrate 52.

[0128] Next, Figure 26 and Figure 29 will be used to describe the configuration included in the non-active region 413NAA of the second substrate 51. As Figure 26 shown, in the non-active region 413NAA of the second substrate 51, a third connection electrode 63 that conducts with the first electrode 56 and a fourth connection electrode 64 that conducts with the second electrode 57 are provided. First, the planar shapes of both the first electrode 56 and the second electrode 57 are square and are one size larger than the active region 413AA. The central side portion of the first electrode 56 is disposed so as to overlap the entire region of the active region 413AA, while the outer peripheral side portion is disposed in the non-active region 413NAA. Similarly to the first electrode 56, the central side portion of the second electrode 57 is disposed so as to overlap the entire region of the active region 413AA, and in contrast, the outer peripheral side portion is disposed in the non-active region 413NAA. That is to say, both the first electrode 56 and the second electrode 57 have a formation range spanning the active region 413AA and the non-active region 413NAA.

[0129] As Figure 26As shown, the third connection electrode 63 is located between the first electrode 56 and the side portions (end portions) 51A and 51B of the second substrate 51 in the non-active region 413NAA of the second substrate 51. The third connection electrode 63 is electrically connected to the end portion of the first electrode 56. That is, the third connection electrode 63 is provided so as to protrude outward from the end portion of the first electrode 56. A plurality of third connection electrodes 63 are arranged at intervals in the direction along the end portion of the first electrode 56 (X-axis direction or Y-axis direction). The third connection electrodes 63 are provided over the entire circumference of the outer peripheral end portion formed by the four end portions of the first electrode 56. That is, a plurality of third connection electrodes 63 are provided at each of the four end portions constituting the outer peripheral end portion of the first electrode 56. The fourth connection electrode 64 is located between the second electrode 57 and the side portions (end portions) 51A and 51B of the second substrate 51 in the non-active region 413NAA of the second substrate 51. The fourth connection electrode 64 is electrically connected to the end portion of the second electrode 57. That is, the fourth connection electrode 64 is provided so as to protrude outward from the end portion of the second electrode 57. A plurality of fourth connection electrodes 64 are arranged at intervals in the direction along the end portion of the second electrode 57. The fourth connection electrodes 64 are provided over the entire circumference of the outer peripheral end portion formed by the four end portions of the second electrode 57. That is, a plurality of fourth connection electrodes 64 are provided at each of the four end portions constituting the outer peripheral end portion of the second electrode 57.

[0130] As Figure 29 shown, the outer peripheral end portions of the first electrode 56 and the second electrode 57 are located on the inner peripheral side (active region 413AA side) relative to the sealing portion 54 and do not overlap with the sealing portion 54. In Figure 29 the figure, the sealing portion 54 is illustrated by a two-dot chain line. The third connection electrode 63 extends from the first electrode 56 in a direction crossing the direction along the end portion of the first electrode 56 (Y-axis direction in Figure 29 the figure) (X-axis direction in Figure 29 the figure). A plurality of third connection electrodes 63 are arranged at intervals in the direction along the end portion of the first electrode 56. The arrangement interval of the plurality of third connection electrodes 63 is larger than the width of the fourth connection electrode 64. The fourth connection electrode 64 extends from the second electrode 57 in a direction crossing the direction along the end portion of the second electrode 57 (Y-axis direction in Figure 29 the figure) (in Figure 29extends in the X-axis direction (the middle is the X-axis direction). A plurality of fourth connection electrodes 64 are arranged at intervals in a direction along the end of the second electrode 57. The arrangement interval of the plurality of fourth connection electrodes 64 is larger than the width of the third connection electrode 63. The third connection electrode 63 and the fourth connection electrode 64 are arranged in a direction along the respective ends of the first electrode 56 and the second electrode 57. The plurality of third connection electrodes 63 and the plurality of fourth connection electrodes 64 are arranged alternately one by one in a direction along the respective ends of the first electrode 56 and the second electrode 57. The plurality of third connection electrodes 63 and the plurality of fourth connection electrodes 64 are arranged to overlap the sealing portion 54 in a top view.

[0131] Next, use Figure 30 The relationship between the first connection electrode 61 and the third connection electrode 63 will be described. The third connection electrode 63 is arranged to overlap the first connection electrode 61. That is, the third connection electrode 63 and the first connection electrode 61 are arranged to face each other with a gap in the Z-axis direction. The third connection electrode 63 is located on the lower layer side of the insulating film 58, that is, on the same layer as the second electrode 57. The third connection electrode 63 is separated from the second electrode 57 on the same layer. The third connection electrode 63 is formed of the same transparent electrode film as the second electrode 57 and is formed of a part different from the second electrode 57 in the transparent electrode film. Therefore, when manufacturing the second substrate 51, the third connection electrode 63 is formed by the same process as the process of forming the second electrode 57. Although most of the third connection electrode 63 does not overlap with the first electrode 56, a part thereof is arranged to overlap with the first electrode 56 with the insulating film 58 interposed therebetween. Specifically, the end on the active region 413AA side of the third connection electrode 63 overlaps with the end of the first electrode 56, and the insulating film 58 is interposed therebetween. A contact hole 58A for connecting the first electrode 56 and the third connection electrode 63 is provided in a part of the insulating film 58 that overlaps the overlapping portion of the first electrode 56 and the third connection electrode 63. The end on the active region 413AA side of the third connection electrode 63 and the end of the first electrode 56 are connected through the contact hole 58A of the insulating film 58.

[0132] As Figure 30As shown, most of the portion of the third connection electrode 63 that does not overlap with the first electrode 56 is arranged to overlap with the sealing portion 54. Here, the sealing portion 54 is composed of a base material 54A and a plurality of conductive particles 54B. The base material 54A is composed of a photocurable resin material, a thermosetting resin material, etc., and the plurality of conductive particles 54B are dispersedly incorporated in the base material 54A. The conductive particles 54B are formed, for example, by performing a conductive plating treatment such as gold plating on the surface of synthetic resin particles. The particle diameter of the conductive particles 54B is set to a value approximate to the cell gap of the sub liquid crystal panel 413. The plurality of conductive particles 54B include conductive particles in a positional relationship of overlapping with the first connection electrode 61 and the third connection electrode 63. The conductive particles 54B in the positional relationship of overlapping with the first connection electrode 61 and the third connection electrode 63 constitute a first conductive portion 65 that contacts the first connection electrode 61 and the third connection electrode 63. The conduction between the first connection electrode 61 and the third connection electrode 63 is achieved through the first conductive portion 65. In this way, a common potential is supplied to the first electrode 56 from the plurality of first connection electrodes 61 respectively connected to the plurality of first wirings 59 (four in number) that surround the first electrode 56 throughout the circumference, via the plurality of first conductive portions 65 and the plurality of third connection electrodes 63. As a result, since the resistance distribution of the first electrode 56 is unlikely to deviate, potential fluctuations are unlikely to occur in the first electrode 56. Moreover, the first conductive portion 65 arranged to overlap with the first connection electrode 61 and the third connection electrode 63 is arranged not to overlap with the second electrode 57. Therefore, even if the number of the conduction portions (the first connection electrode 61, the first conductive portion 65, and the third connection electrode 63) of the first wiring 59 and the first electrode 56 increases as described above, it is possible to avoid the short circuit between the third connection electrode 63 and the second electrode 57 due to the first conductive portion 65. In this way, the connection reliability can be improved. In addition, although the end portion of the third connection electrode 63 on the side opposite to the active region 413AA side does not overlap with the sealing portion 54, it is covered by the insulating film 58. In this way, the end portion of the third connection electrode 63 located outside the sealing portion 54 can be protected by the insulating film 58.

[0133] Next, the relationship between the second connection electrode 62 and the fourth connection electrode 64 will be described. As Figure 31 shown in Figure 31As shown, the fourth connection electrode 64 is disposed overlapping the second connection electrode 62. That is, the fourth connection electrode 64 is disposed opposite to the second connection electrode 62 with a gap therebetween in the Z-axis direction. The fourth connection electrode 64 is located on the lower layer side of the insulating film 58, that is, on the same layer as the second electrode 57. The fourth connection electrode 64 is formed of the same transparent electrode film as the second electrode 57 and is formed of a portion different from the second electrode 57 in the transparent electrode film. Therefore, when manufacturing the second substrate 51, the fourth connection electrode 64 is formed by the same process as the process of forming the second electrode 57. The end portion of the fourth connection electrode 64 on the active region 413AA side is connected to the end portion of the second electrode 57 on the same layer, thereby achieving conduction between the fourth connection electrode 64 and the second electrode 57. In addition, although the fourth connection electrode 64 is disposed such that the end portion on the active region 413AA side overlaps the first electrode 56, the remaining portion is located outside the end portion of the first electrode 56 (on the side opposite to the active region 413AA side) and does not overlap the first electrode 56.

[0134] As Figure 31 shown, most of the portion of the fourth connection electrode 64 that does not overlap the first electrode 56 is disposed overlapping the sealing portion 54. Among the plurality of conductive particles 54B included in the sealing portion 54, there are conductive particles in a positional relationship overlapping the second connection electrode 62 and the fourth connection electrode 64. The conductive particles 54B in the positional relationship overlapping the second connection electrode 62 and the fourth connection electrode 64 constitute a second conductive portion 66 that contacts the second connection electrode 62 and the fourth connection electrode 64. Conduction between the second connection electrode 62 and the fourth connection electrode 64 is achieved through the second conductive portion 66. In this way, a ground potential is supplied to the second electrode 57 from the plurality of second connection electrodes 62 respectively connected to the plurality of (four) second wirings 60 surrounding the second electrode 57 throughout the circumference via the plurality of second conductive portions 66 and the plurality of fourth connection electrodes 64. As a result, since it is difficult for the resistance distribution of the second electrode 57 to deviate, it is difficult for the second electrode 57 to have a potential change. Moreover, the second conductive portion 66 disposed overlapping the second connection electrode 62 and the fourth connection electrode 64 is disposed not overlapping the first electrode 56. Therefore, even if the number of the conduction portions (the second connection electrode 62, the second conductive portion 66, and the fourth connection electrode 64) between the second wiring 60 and the second electrode 57 increases as described above, it is possible to avoid a short circuit between the fourth connection electrode 64 and the first electrode 56 due to the second conductive portion 66. In this way, an improvement in connection reliability can be achieved. In addition, although the end portion of the fourth connection electrode 64 on the side opposite to the active region 413AA side does not overlap the sealing portion 54, it is covered by the insulating film 58. In this way, the end portion of the fourth connection electrode 64 located outside the sealing portion 54 can be protected by the insulating film 58.

[0135] In addition, asFigure 30 and Figure 31 As shown in Figure 31 , both the third connection electrode 63 and the fourth connection electrode 64 are on the same layer as the second electrode 57. The first connection electrode 61 and the second connection electrode 62 are on the same layer as each other. Therefore, the Z-axis direction interval between the relatively opposed first connection electrode 61 and the third connection electrode 63 and the Z-axis direction interval between the relatively opposed second connection electrode 62 and the fourth connection electrode 64 are substantially the same. Thereby, the first conductive portion 65 interposed between the first connection electrode 61 and the third connection electrode 63 and the second conductive portion 66 interposed between the second connection electrode 62 and the fourth connection electrode 64 can be made to have substantially the same height. The first conductive portion 65 and the second conductive portion 66 are a part of the plurality of conductive particles 54B included in the sealing portion 54 as described. Therefore, the sealing portion 54 only needs to contain conductive particles 54B of one particle size, which can achieve a reduction in material cost and also improve connection reliability.

[0136] As described above, the sub-liquid crystal panel (electronic device) 413 of the present embodiment includes: a first substrate 50; a second substrate 51 disposed opposite to the first substrate 50; a first wiring 59 provided on the first substrate 50; a second wiring 60 provided on the first substrate 50, disposed at a position spaced apart from the first wiring 59, and extending in parallel with the first wiring 59; a first connection electrode 61 protruding from the first wiring 59 toward the second wiring 60 side; a second connection electrode 62 protruding from the second wiring 60 toward the first wiring 59 side and arranged in the extending direction of the first connection electrode 61 and the second wiring 60; a first electrode 56 provided on the second substrate 51; a third connection electrode 63 provided on the second substrate 51, electrically connected to the first electrode 56 and disposed overlapping the first connection electrode 61; a second electrode 57 provided on the second substrate 51; a fourth connection electrode 64 provided on the second substrate 51, electrically connected to the second electrode 57 and disposed overlapping the second connection electrode 62 and juxtaposed with the third connection electrode 63 in the extending direction; a first conductive portion 65 interposed between the first substrate 50 and the second substrate 51, disposed overlapping the first connection electrode 61 and the third connection electrode 63, and in contact with the first connection electrode 61 and the third connection electrode 63; and a second conductive portion 66 interposed between the first substrate 50 and the second substrate 51, disposed overlapping the second connection electrode 62 and the fourth connection electrode 64, and in contact with the second connection electrode 62 and the fourth connection electrode 64.

[0137] The potential of the first wiring 59 is supplied to the first electrode 56 via the first connection electrode 61, the first conductive portion 65, and the third connection electrode 63. The potential of the second wiring 60 is supplied to the second electrode 57 via the second connection electrode 62, the second conductive portion 66, and the fourth connection electrode 64. The first connection electrode 61 protruding from the first wiring 59 toward the second wiring 60 side and the second connection electrode 62 protruding from the second wiring 60 toward the first wiring 59 side are arranged along the extending direction of the second wiring 60. The third connection electrode 63 electrically connected to the first electrode 56 is arranged to overlap with the first connection electrode 61, and the fourth connection electrode 64 electrically connected to the second electrode 57 is arranged to overlap with the second connection electrode 62. According to this configuration, the first conductive portion 65 arranged to overlap with the first connection electrode 61 and the third connection electrode 63 is arranged so as not to overlap with the second electrode 57, and the second conductive portion 66 arranged to overlap with the second connection electrode 62 and the fourth connection electrode 64 is arranged so as not to overlap with the first electrode 56. Therefore, even when the number of the conduction portions (the first connection electrode 61, the first conductive portion 65, and the third connection electrode 63) between the first wiring 59 and the first electrode 56 and the number of the conduction portions (the second connection electrode 62, the second conductive portion 66, and the fourth connection electrode 64) between the second wiring 60 and the second electrode 57 are increased respectively, it is possible to avoid the short circuit between the third connection electrode 63 and the second electrode 57 due to the first conductive portion 65, and it is possible to avoid the short circuit between the fourth connection electrode 64 and the first electrode 56 due to the second conductive portion 66. Through the above, it is possible to improve the connection reliability. In addition, it is preferable to make the resistance distribution of the first electrode 56 and the second electrode 57 difficult to deviate. In addition, since the first connection electrode 61 and the second connection electrode 62 are sandwiched between the first wiring 59 and the second wiring 60, the space efficiency is good, and it is also preferable for achieving a narrow bezel.

[0138] <Sixth Embodiment>

[0139] By Figure 32 The sixth embodiment will be described. In this sixth embodiment, it shows a case where a touch panel 70 is provided instead of the sub liquid crystal panel 13 described in the above first embodiment. In addition, the repeated description of the same structures, operations, and effects as those in the above first embodiment is omitted.

[0140] As Figure 32As shown, the liquid crystal display device 510 of the present embodiment includes a touch panel 70 disposed so as to overlap the front side of the liquid crystal panel 511 (the side opposite to the backlight device 512 side). The touch panel 70 has a touch panel function of detecting the position (input position) of a user input based on an image displayed on the liquid crystal panel 511. A touch panel pattern for realizing the touch panel function is provided on the touch panel 70. The touch panel pattern is, for example, a projection type capacitive method, and the detection method is a self-capacitance method or a mutual-capacitance method. The touch panel pattern is constituted by, for example, a plurality of touch electrodes (position detection electrodes) arranged in a matrix in the main surface of the touch panel 70. In the main surface of the touch panel 70, the area where the plurality of touch electrodes are arranged is a touch area (position input area) capable of detecting the input position. The touch panel 70 is arranged such that the touch area overlaps with the display area AA of the liquid crystal panel 511 (refer to Figure 1 ). According to such a configuration, when a position input is performed based on the image of the display area AA of the liquid crystal panel 511 visually recognized by the user and a finger (position input body) as a conductor approaches the surface of the liquid crystal panel 511, a capacitance is formed between the finger and the touch electrode. As a result, the capacitance detected by the touch electrode near the finger changes as the finger approaches, which is different from the touch electrode far from the finger, so that the input position can be detected based on this.

[0141] In the touch panel 70 as described above, during position detection, a touch signal is input to the plurality of touch electrodes. Along with the input of the touch signal, it is possible to input noise to the liquid crystal panel 511 from the front side. Even in such a case, as described in the first embodiment, a second electrode 24 is provided on the opposing substrate 11A of the liquid crystal panel 511 (refer to Figure 5 ). The noise emitted from the touch panel 70 is shielded by the second electrode 24, so that it is not easy to generate a potential change on the first electrode 23. Moreover, since a capacitance is formed between the mutually overlapping first electrode 23 and the second electrode 24, it is possible to suppress the potential change of the first electrode 23. In this way, by suppressing the potential change of the first electrode 23, the display quality of the image displayed on the liquid crystal panel 511 becomes good. Moreover, the first conductive portion 32 disposed to overlap the first connection electrode 28 and the third connection electrode 30 is arranged not to overlap with the second electrode 24, and the second conductive portion 33 disposed to overlap the second connection electrode 29 and the fourth connection electrode 31 is arranged not to overlap with the first electrode 23 (refer to Figure 10 and Figure 11 ). Thereby, the situation where the third connection electrode 30 and the second electrode 24 are short-circuited due to the first conductive portion 32 is avoided, and the situation where the fourth connection electrode 31 and the first electrode 23 are short-circuited due to the second conductive portion 33 is avoided, so that an improvement in connection reliability can be achieved.

Specifically, the first wirings 26, 59, 126, 226, 326 may be arranged on the side opposite to the display area AA (active area 413AA) side with respect to the second wirings 27, 60, 127, 227, 327 (sealing portions 11D, 54, 211D, 311D), and the second wirings 27, 60, 127, 227, 327 may be arranged on the display area (active area 413AA) AA side with respect to the first wirings 26, 59, 126, 226, 326 (sealing portions 11D, 54, 211D, 311D).

[0151] (8) As a modification of the fourth embodiment, the third connection electrode 330 may be arranged on the same layer as the first electrode 323. In this case, the insulating film 325 and the sixth contact hole 47B of the third insulating film 47 are not required. Further, in this case, the fourth connection electrode 331 and the sixth connection electrode 48 may be arranged on the same layer as the third connection electrode 330 and the first electrode 323.

[0152] (9) As a modification of the fourth embodiment, the fourth connection electrode 331 may be arranged on the same layer as the second electrode 324.

Further, in this case, the third connection electrode 330 and the sixth connection electrode 48 may be arranged on the same layer as the fourth connection electrode 331 and the second electrode 324.

[0153] (10) As a modification of the fourth embodiment, the sixth connection electrode 48 may be arranged on the same layer as the first electrode 323. In this case, new contact holes are provided in the insulating film 325 and the third insulating film 47, and the sixth connection electrode 48 may be made conductive with the third electrode 46 through these contact holes.

[0154] (11) As a modification of the fourth embodiment, the sixth connection electrode 48 may be arranged on the same layer as the second electrode 324. In this case, a new contact hole is provided in the third insulating film 47, and the sixth connection electrode 48 may be made conductive with the third electrode 46 through this contact hole.

[0155] (12) It is also possible to combine the configurations described in the second embodiment and the third embodiment with the configuration described in the fourth embodiment.

[0156] (13) As long as the first wirings 26, 59, 126, 226, 326 and the second wirings 27, 60, 127, 227, 327 extend in parallel with each other, they may extend in a non-linear shape (including a curved shape or the like) or in a serpentine bend. The same applies to the third wiring 42 described in the fourth embodiment.

[0157] (14) A plurality of the first connection electrodes 28, 61, 228, 328 or the second connection electrodes 29, 62, 329 may be continuously arranged in the extending direction of the first wirings 26, 59, 126, 226, 326 and the second wirings 27, 60, 127, 227, 327.

[0158] (15) The first electrodes 23, 56, 123, 223, 323 and the second electrodes 24, 57, 124, 224, 324 can be arranged in a non-overlapping configuration with each other. In this case, the insulating films 25, 58, 125, 225, 325 are not required. Specifically, in the first to fourth embodiments and the sixth embodiment, for example, in the non-display area NAA of the array substrates 11B, 111B, 311B, when a gate circuit unit for supplying a scan signal to the gate wiring 16 is provided monolithically, the second electrodes 24, 124, 224, 324 are arranged in the non-display area NAA so as to overlap with the gate circuit unit, and the first electrodes 23, 123, 223, 323 are arranged in the display area AA so as not to overlap with the second electrodes 24, 124, 224, 324 and the gate circuit unit.

[0159] (16) The second electrodes 24, 57, 124, 224, 324 can also be arranged in a configuration where they overlap with a part of the first electrodes 23, 56, 123, 223, 323. Specifically, in the first to fourth embodiments and the sixth embodiment, for example, also in the non-display area NAA of the array substrates 11B, 111B, 311B, when a gate circuit unit for supplying a scan signal to the gate wiring 16 is provided monolithically, the second electrodes 24, 124, 224, 324 are arranged in the non-display area NAA so as to overlap with the gate circuit unit, a part of the first electrodes 23, 123, 223, 323 overlaps with the second electrodes 24, 124, 224, 324 and the gate circuit unit in the non-display area NAA, and the remaining part is arranged in the display area AA so as not to overlap with the second electrodes 24, 124, 224, 324 and the gate circuit unit.

[0160] (17) The potential supplied to the first electrodes 23, 56, 123, 223, 323 through the first wirings 26, 59, 126, 226, 326 can be a potential other than the common potential. Similarly, the potential supplied to the second electrodes 24, 57, 124, 224, 324 through the second wirings 27, 60, 127, 227, 327 can also be a potential other than the ground potential. Similarly, the potential supplied to the third electrode 46 through the third wiring 42 can also be a potential other than the touch panel drive signal potential.

[0161] (18) The specific constitution of the conductive particles 11D2, 54B can be appropriately changed.

[0162] (19) The first conductive portions 32, 65, 332 and the second conductive portions 33, 66, 233, 333 may also be made of materials other than the conductive particles 11D2, 54B contained in the sealing portions 11D, 54, 211D, 311D. That is to say, the first conductive portions 32, 65, 332 and the second conductive portions 33, 66, 233, 333 may also be disposed outside the sealing portions 11D, 54, 211D, 311D. In this case, the first connection electrodes 28, 61, 228, 328, the second connection electrodes 29, 62, 329, the third connection electrodes 30, 63, 130, 230, 330, and the fourth connection electrodes 31, 64, 131, 231, 331 may also be disposed at positions not overlapping with the sealing portions 11D, 54, 211D, 311D. The same applies to the third conductive portion 49, the fifth connection electrode 43, and the sixth connection electrode 48 described in the fourth embodiment.

[0163] (20) In the first to fourth embodiments and the sixth embodiment, the number of electrodes provided on the opposing substrates 11A, 111A, 211A, 311A may also be four or more. In addition, in the fifth embodiment, the number of electrodes provided on the second substrate 51 may also be three or more.

[0164] (21) The display mode of the liquid crystal panels 11, 511 may also be a TN (Twisted Nematic) mode or the like.

[0165] (22) The liquid crystal display device 10 may also be one that does not include the sub liquid crystal panel 13.

[0166] (23) The sub liquid crystal panels 13, 413 may also be disposed overlappingly on the back side with respect to the liquid crystal panels 11, 511. In this case, the sub liquid crystal panels 13, 413 are disposed between the liquid crystal panels 11, 511 and the backlight device 12.

[0167] (24) In the fifth embodiment, the liquid crystal panel 11 may also be configured without the second electrode 24, the insulating film 25, the first wiring 26, the second wiring 27, the first connection electrode 28, the second connection electrode 29, the third connection electrode 30, the fourth connection electrode 31, the first conductive portion 32, and the second conductive portion 33, etc.

[0168] (25) In the fifth embodiment, the liquid crystal panel 11 may also be a display panel such as an organic EL display panel. In the case where the display panel is a self-luminous type such as an organic EL display panel, the backlight device 12 can be omitted.

[0169] The configuration described in the fifth embodiment can be combined with the configurations described in the second to fourth embodiments. Similarly, the configuration described in the sixth embodiment can also be combined with the configurations described in the second to fifth embodiments.
