Description

[Technical Field]

[0001] The technology disclosed in this specification relates to a display device in which the load on control wiring is reduced and a narrower frame is achieved. [Background technology]

[0002] Known examples of conventional display devices include those described in the following Patent Documents 1 to 3. In the liquid crystal display device described in Patent Document 1, the input signal wiring of the built-in integrated circuit made of low-temperature polycrystalline silicon TFT is arranged in the area of ​​the IC mounted on the liquid crystal display device by COG, so that the extraction electrode terminals for the low-temperature polycrystalline silicon integrated circuit are arranged on both sides of the extraction electrode terminals for the IC, thereby narrowing the non-display area required for the extraction electrode terminals.

[0003] The liquid crystal display device described in Patent Document 2 is a display device comprising a liquid crystal panel having a display section and a non-display section, a driver that is elongated along the sides of the liquid crystal panel, a panel-side output terminal section connected to the driver, a plurality of image signal wirings that are drawn out from the panel-side output terminal section across the long sides of the driver and routed in a fan-like pattern towards the display section, transmitting image signals, a plurality of control signal wirings that are drawn out from the panel-side output terminal section towards the display section and transmit control signals, first control signal wirings that are drawn out towards the display section following the image signal wirings, and second control signal wirings that are drawn out from the panel-side output terminal section across the short sides of the driver and have a line width that is wider than the first control signal wirings in at least some parts.

[0004] The liquid crystal panel, which is a display device described in Patent Document 3, has a structure in which two substrates are bonded together, and includes a base substrate, a pixel array consisting of display elements arranged two-dimensionally on the base substrate, an element-side substrate arranged along one side of the pixel array on the base substrate and including control circuits that control the display elements row by row or column by column, and an opposing substrate facing the element-side substrate, and the control circuit has a configuration in which unit control circuits corresponding to control units of display elements are arranged continuously in one dimension, the arrangement spacing of the unit control circuits being narrower than the arrangement spacing of control units of display elements, and the difference between the two is equal to or less than the minimum wiring width or minimum wiring spacing allowed for the control circuit.

[0006] [Patent Document 2] International Publication No. 2014 / 013945

[0007] [Patent Document 3] International Publication No. 2007 / 026446 Summary of the Invention [Problem to be solved by the invention]

[0008] In Patent Document 1, the input signal wiring is routed across the IC area from the extraction electrode terminal for the low-temperature polycrystalline silicon integrated circuit to the built-in integrated circuit, which tends to make the wiring length of the input signal wiring long, raising concerns about an increased load on the input signal wiring.

[0009] In Patent Document 2, the first control signal wiring, which is routed from the panel-side output terminal section toward the display section following the image signal wiring, is connected to an end of the column control circuit section extending along the long side of the driver. This first control signal wiring is arranged closer to the end than the image signal wiring located at the endmost position among the multiple image signal wirings, so the wiring length of the first control signal wiring tends to be long, which raises concerns about an increased load on the first control signal wiring. Furthermore, it is necessary to secure space for arranging the first control signal wiring near the end of the non-display section in the long side of the driver, which may result in a wider frame of the liquid crystal panel.

[0010] In Patent Document 3, the wiring routed from the external terminal is connected to an end portion in the extending direction of the horizontally elongated column control circuit. In other words, the wiring described in Patent Document 3 has the same configuration as the first control signal wiring described in Patent Document 2, and the wiring length tends to be long, which raises concerns about an increase in the wiring load.

[0011] The technology described in this specification was developed based on the above circumstances, and aims to reduce the load on the control wiring and achieve a narrower frame. [Means for solving the problem]

[0022] <Embodiment 1> Embodiment 1 will be described with reference to Figs. 1 to 7. In this embodiment, a liquid crystal display device (display device) 10 will be illustrated. Note that X-axis, Y-axis, and Z-axis are shown in parts of each drawing, and each axis direction is depicted as being in the direction shown in each drawing. Also, the upper side of Figs. 2 and 6 is the front side, and the lower side of the drawings is the back side.

[0023] As shown in Fig. 1, a liquid crystal display device 10 includes at least a horizontally elongated rectangular liquid crystal panel (display panel) 11 capable of displaying images, and a backlight device (illumination device) that irradiates the liquid crystal panel 11 with light to be used for display. The backlight device is disposed on the rear side (back surface) of the liquid crystal panel 11 and includes a light source (e.g., an LED) that emits white light and optical components that convert the light from the light source into planar light by applying an optical effect. The central portion of the main surface 11S of the liquid crystal panel 11 is a display area AA where an image is displayed. In contrast, a frame-shaped outer peripheral portion of the main surface 11S of the liquid crystal panel 11 that surrounds the display area AA is a non-display area NAA where no image is displayed.

[0024] The liquid crystal panel 11 will be described with reference to FIG. 1 and FIG. 2. As shown in FIGS. 1 and 2, the liquid crystal panel 11 is formed by bonding a pair of substrates 20, 21 together. The front side of the pair of substrates 20, 21 is the counter substrate 20, and the back side is the array substrate 21. The counter substrate 20 and the array substrate 21 are both formed by laminating various films on the inner surface of glass substrates. A liquid crystal layer 22 containing liquid crystal molecules, which are a substance whose optical properties change when an electric field is applied, is disposed between the pair of substrates 20, 21. A seal portion 23 that seals the liquid crystal layer 22 is disposed between the outer peripheral edges of the pair of substrates 20, 21. The seal portion 23 is formed in a rectangular frame shape so as to surround the liquid crystal layer 22. A polarizing plate 14 is attached to the outer surface of each of the substrates 20, 21.

[0025] 1 and 2, the short side dimension of the counter substrate 20 is shorter than the short side dimension of the array substrate 21. The counter substrate 20 is attached to the array substrate 21 so that one end in the short side direction (Y-axis direction) is aligned with the array substrate 21. Therefore, the other end in the short side direction of the array substrate 21 is an exposed portion 21A that protrudes laterally from the counter substrate 20 and is exposed. The entire exposed portion 21A is a non-display area NAA, and a driver 12 and a flexible substrate 13 for supplying various signals are mounted on the exposed portion 21A.

[0026] As shown in FIGS. 1 and 2, the driver 12 is mounted on the exposed portion 21A of the array substrate 21 by COG (Chip On Glass). The driver 12 is an LSI chip with an internal drive circuit. The driver 12 processes various signals transmitted by the flexible substrate 13. The driver 12 is arranged adjacent to one side of the display area AA in the Y-axis direction in the exposed portion 21A, and is sandwiched between the display area AA and the flexible substrate 13 (described below). One driver 12 is arranged near the center of the exposed portion 21A in the X-axis direction. The driver 12 has a horizontally elongated rectangular shape in plan view. The long side of the driver 12 is smaller than the long side of the display area AA. The outer periphery of the driver 12 includes a pair of long sides and a pair of short sides. Of the pair of long sides of the driver 12, the long side closest to the display area AA is designated as the first side 12A, which is closest to the display area AA within the outer periphery. A pair of short sides of the driver 12 are both connected to a first side 12A, and one of these short sides (the left side in FIG. 1) is a second side 12B. The first side 12A is parallel to the X-axis direction (first direction). The second side 12B is parallel to the Y-axis direction (second direction intersecting the first direction).

[0027] The flexible substrate 13 is configured by forming a large number of wiring patterns on a base material made of an insulating and flexible synthetic resin material (e.g., polyimide resin, etc.). As shown in Figures 1 and 2, one end of the flexible substrate 13 is connected to the exposed portion 21A of the array substrate 21, and the other end is connected to an external circuit board (e.g., a control board). The flexible substrate 13 is connected to an end of the exposed portion 21A on the opposite side of the display area AA in the Y-axis direction from the driver 12. In other words, the flexible substrate 13 is attached to the exposed portion 21A at a position where the driver 12 is sandwiched between the flexible substrate 13 and the display area AA.

[0028] 1, a gate drive circuit 15 and a switch circuit (first circuit portion) 16 are provided in the non-display area NAA of the array substrate 21. A pair of gate drive circuits 15 are provided to sandwich the display area AA from both sides in the X-axis direction. The gate drive circuit 15 is provided in a vertically long strip-shaped range extending along the short side direction (Y-axis direction) of the array substrate 21. The gate drive circuit 15 is for supplying scanning signals to gate wiring 26, which will be described later, and is provided monolithically on the array substrate 21.

[0029] As shown in FIG. 1 , the switch circuit 16 is disposed in the non-display area NAA, sandwiched between the display area AA and the driver 12 in the Y-axis direction. The switch circuit 16 is provided in a horizontally elongated band-shaped area extending along the long side direction (X-axis direction) of the array substrate 21. A pair of switch circuits 16 are disposed side by side with a gap in the X-axis direction. One end of each switch circuit 16 in its extension direction (X-axis direction) is a first end 16A located toward the center of the non-display area NAA in the X-axis direction. The other end of each switch circuit 16 in its extension direction is a second end 16B located toward the edge of the non-display area NAA in the X-axis direction. The switch circuit 16 has a switching function that distributes image signals supplied from the driver 12 to source lines 27 (described later) and is a so-called SSD (Source Shared Driving) circuit. The specific circuit configuration of the switch circuit 16 will be described in detail later.

[0030] As shown in Fig. 1, a common electrode 28 is provided in the display area AA and non-display area NAA of the array substrate 21. The common electrode 28 is disposed solidly across the entire display area AA, with its outer periphery located in the non-display area NAA. A common wiring 29 connected to the common electrode 28 is disposed in the non-display area NAA of the array substrate 21. A pair of common wirings 29 are disposed to sandwich the display area AA from both sides in the X-axis direction, and are arranged to overlap both ends of the common electrode 28 in the X-axis direction. The common electrode 28 will be described in detail later.

[0031] Next, the configuration of the display area AA of the array substrate 21 will be described with reference to FIG. 3. As shown in FIG. 3, at least TFTs (thin film transistors, switching elements) 24 and pixel electrodes 25 are provided on the inner surface of the display area AA of the array substrate 21. The TFTs 24 and pixel electrodes 25 are arranged in a matrix (rows and columns) with multiple TFTs 24 and multiple pixel electrodes 25 spaced apart along the X-axis and Y-axis directions. Gate wiring (scanning wiring) 26 and source wiring (signal wiring, image wiring) 27 are arranged around the TFTs 24 and pixel electrodes 25, intersecting each other at right angles. The gate wiring 26 extends along the X-axis direction, with multiple wirings spaced apart along the Y-axis. The source wiring 27 extends along the Y-axis direction, with multiple wirings spaced apart along the X-axis. The gate wiring 26 is made of a part of a first metal film. The source wiring 27 is made of a part of a second metal film that is arranged above the first metal film with a gate insulating film interposed therebetween. The gate wiring 26 and source wiring 27 that intersect with each other are kept in an insulated state by the gate insulating film interposed therebetween. The first metal film and the second metal film are each a single layer film made of one type of metal material, or a laminated film or alloy made of different types of metal materials, and are therefore conductive. Examples of materials that can be used for the first metal film and the second metal film include tantalum, molybdenum, titanium, and aluminum. The gate insulating film can also be made of silicon nitride (SiN x ), and silicon dioxide (SiO2), among other inorganic materials.

[0032] As shown in FIG. 3 , the TFT 24 includes a gate electrode 24A connected to the gate line 26, a source electrode 24B connected to the source line 27, a drain electrode 24C connected to the pixel electrode 25, and a semiconductor portion 24D made of a semiconductor material and connected to the source electrode 24B and the drain electrode 24C. The gate electrode 24A is made of a portion of a first metal film. The source electrode 24B and the drain electrode 24C are each made of a portion of a second metal film. The semiconductor portion 24D is made of a portion of a semiconductor film located above the gate insulating film and below the second metal film. The semiconductor film is made of a polycrystalline polysilicon semiconductor material or an oxide semiconductor material. The TFT 24 is driven based on a scanning signal supplied to the gate electrode 24A by the gate line 26. Then, a potential corresponding to an image signal (data signal) supplied from the driver 12 to the source electrode 24B via the source line 27 is supplied to the drain electrode 24C via the semiconductor portion 24D. As a result, the pixel electrode 25 is charged to a potential corresponding to the image signal.

[0033] As shown in FIG. 3, the pixel electrode 25 is disposed in a region surrounded by the gate wiring 26 and the source wiring 27, and has a planar shape of, for example, a substantially rectangular shape. The pixel electrode 25 is made of a part of a first transparent electrode film disposed above the second metal film constituting the drain electrode 24C, with one or two insulating films interposed therebetween. The first transparent electrode film is made of a transparent electrode material (e.g., ITO (Indium Tin Oxide) or IZO (Indium Zinc Oxide)). When one insulating film is interposed between the second metal film and the first transparent electrode film, the insulating film is made of an organic material such as PMMA (acrylic resin). When two insulating films are interposed between the second metal film and the first transparent electrode film, the lower insulating film of the two insulating films is made of, for example, an inorganic material similar to the gate insulating film, and the upper insulating film is made of an organic material such as PMMA (acrylic resin). The pixel electrode 25 overlaps a color filter disposed in the display region AA of the counter substrate 20, and together with the color filter, forms a pixel. The color filters are, for example, of three colors: red (R), green (G), and blue (B). In this liquid crystal panel 11, the R, G, and B color filters aligned along the X-axis direction and three pixel electrodes 25 facing each color filter form three-color sub-pixels. The three sub-pixels form one display pixel capable of color display.

[0034] The common electrode 28 shown in FIG. 1 is disposed so as to overlap all of the pixel electrodes 25 disposed in the display area AA. A slit is formed in each portion of the common electrode 28 that overlaps each pixel electrode 25. The common electrode 28 is made of a part of a second transparent electrode film that is disposed above the first transparent electrode film constituting the pixel electrodes 25, with an insulating film interposed therebetween. The second transparent electrode film is made of the same transparent electrode material as the first transparent electrode film. The insulating film interposed between the first transparent electrode film and the second transparent electrode film is made of the same inorganic material as the gate insulating film. A common potential (reference potential) is supplied to the common electrode 28 by a common wiring 29. When the pixel electrodes 25 are charged to a potential based on an image signal transmitted to the source wiring 27 as the TFTs 24 are driven, a potential difference is generated between the pixel electrodes 25 and the common electrode 28. As a result, a fringe electric field is generated between the opening edge of the slit in the common electrode 28 and the pixel electrode 25, which includes a component normal to the main surface of the array substrate 21 in addition to a component along the main surface of the array substrate 21. Therefore, by utilizing this fringe electric field, the orientation state of the liquid crystal molecules contained in the liquid crystal layer 22 can be controlled, and a predetermined display is produced based on the orientation state of the liquid crystal molecules. In other words, the liquid crystal panel 11 according to this embodiment operates in FFS (Fringe Field Switching) mode. Note that an orientation film for aligning the liquid crystal molecules contained in the liquid crystal layer 22 is provided on the innermost surfaces of both substrates 20 and 21.

[0035] As shown in FIG. 4 , the inner surface of the exposed portion 21A, which is the non-display area NAA of the array substrate 21, is provided with wiring and terminals for supplying various signals (potentials) to the gate wiring 26, source wiring 27, etc. A plurality of terminal units 30, 31 are provided in a placement area (mounting area) of the driver 12 that overlaps the driver 12 in a plan view of the exposed portion 21A. The plurality of terminal units 30, 31 are arranged to overlap the driver 12 mounted on the exposed portion 21A and are connected to the driver 12. A plurality of flexible substrate terminal units 32 are provided in a placement area of ​​the exposed portion 21A for the flexible substrate 13. The input terminal unit 30, the output terminal unit 31, and the flexible substrate terminal unit 32 are all formed using a first metal film and a second metal film, and are covered on the top layer with a transparent electrode made of a first transparent electrode film and a second transparent electrode film. The plurality of flexible substrate terminal units 32 are arranged to overlap the flexible substrate 13 to be mounted and are connected to the flexible substrate 13. The multiple flexible substrate terminal units 32 are arranged in a row along the X-axis direction at intervals, and each terminal unit has a vertically elongated rectangular shape in plan view. The flexible substrate terminal units 32 are larger in size and area in plan view than the terminal units 30, 31 arranged in the driver 12 placement area. The multiple flexible substrate terminal units 32 include a driver terminal unit 32A to which a signal for driving the driver 12 is supplied via the flexible substrate 13, a power supply terminal unit 32B to which a power supply voltage for driving the gate drive circuit 15 is supplied via the flexible substrate 13, and a common potential terminal unit 32C to which a common potential for supplying to the common electrode 28 is supplied via the flexible substrate 13. A power supply wiring 36 connected to the power supply terminal unit 32B and the gate drive circuit 15 is provided in the non-display area NAA of the array substrate 21. The power supply wiring 36 is formed using a first metal film and a second metal film. The common potential terminal unit 32C is connected to the common wiring 29. In FIG. 4, the outer shape of the driver 12 mounted on the exposed portion 21A is shown by a two-dot chain line.

[0036] 4, the multiple terminal units 30, 31 arranged in the arrangement area of ​​the driver 12 include multiple input terminal units 30 for inputting signals to the driver 12 and multiple output terminal units 31 for receiving signals output from the driver 12. The input terminal units 30 and the output terminal units 31 each have a vertically elongated rectangular shape in plan view, with their long sides parallel to the Y-axis direction and their short sides parallel to the X-axis direction. There are more output terminal units 31 installed than input terminal units 30. Note that signals output from the driver 12 to the output terminal units 31 include image signals, switch signals (control signals), clock signals, initialization signals, gate start pulse signals, etc.

[0037] As shown in FIG. 4 , the input terminal unit 30 is located farther from the display area AA (first side 12A of the driver 12) in the Y-axis direction than the output terminal unit 31. Specifically, the input terminal unit 30 is disposed in a position close to the side of the outer periphery of the driver 12 farthest from the display area AA in the Y-axis direction. The multiple input terminal units 30 form a row along the X-axis direction and are linearly arranged side by side at intervals along the X-axis direction. That is, the positions of both ends of each of the multiple input terminal units 30 in the Y-axis direction are approximately aligned. The multiple input terminal units 30 are individually connected to multiple flexible substrate terminal units 32 arranged at intervals in the Y-axis direction via inter-terminal connection wiring 37. The inter-terminal connection wiring 37 is disposed across the mounting area of ​​the driver 12 and the mounting area of ​​the flexible substrate 13 in the non-display area NAA of the array substrate 21. The inter-terminal connection wiring 37 is formed using a first metal film and a second metal film.

[0038] As shown in FIG. 4, the output terminal unit 31 is located closer to the display area AA (first side 12A of the driver 12) in the Y-axis direction than the input terminal unit 30. Specifically, the output terminal unit 31 is arranged in a position close to the first side 12A, which is closest to the display area AA, on the outer periphery of the driver 12 in the Y-axis direction. The multiple output terminal units 31 form a row along the X-axis direction and are linearly arranged side by side at intervals along the X-axis direction. In other words, the multiple output terminal units 31 are aligned so that both ends of each unit are positioned approximately the same in the Y-axis direction. The types of the multiple output terminal units 31 will be described in detail later.

[0039] As shown in FIG. 5 , the driver 12 has a main surface (bottom surface, back surface) facing the array substrate 21 provided with a plurality of bumps 33, 34 connected to a plurality of terminal portions 30, 31. The bumps 33, 34 are provided to protrude along the Z-axis direction from the main surface of the driver 12 toward the array substrate 21. The bumps 33, 34 are connected to a circuit provided inside the driver 12. A plurality of the bumps 33, 34 are arranged side by side on the main surface of the driver 12 at positions overlapping the respective terminal portions 30, 31 on the array substrate 21 side. The plurality of bumps 33, 34 include a plurality of input bumps 33 for receiving signals from the array substrate 21 and a plurality of output bumps 34 for outputting signals to the array substrate 21. The input bumps 33 and the output bumps 34 each have a vertically elongated rectangular planar shape, with their long sides aligned parallel to the Y-axis direction and their short sides aligned parallel to the X-axis direction.

[0040] 5, the input bumps 33 are positioned farther from the first side 12A (display area AA) of the driver 12 in the Y-axis direction than the output bumps 34. The input bumps 33 form a row along the X-axis direction and are arranged linearly spaced apart along the X-axis direction. In other words, the two ends of the input bumps 33 are aligned so that they are substantially flush with each other in the Y-axis direction. When the driver 12 is attached to the array substrate 21, the input bumps 33 are arranged in positions that overlap the input terminal units 30 in a plan view and are connected to the overlapping input terminal units 30.

[0041] 5, the output bumps 34 are located closer to the first side 12A (display area AA) of the driver 12 in the Y-axis direction than the input bumps 33. The output bumps 34 form a row along the X-axis direction and are arranged linearly spaced apart along the X-axis direction. In other words, the two ends of the output bumps 34 are aligned so that they are substantially flush with each other in the Y-axis direction. When the driver 12 is attached to the array substrate 21, the output bumps 34 are arranged in positions that overlap the output terminal portions 31 in a plan view and are connected to the overlapping output terminal portions 31.

[0042] As shown in FIG. 6, the terminal portions 30, 31 on the array substrate 21 and the bumps 33, 34 on the driver 12 are connected via an anisotropic conductive film (ACF) 35. While FIG. 6 shows the connection structure of the output terminal portion 31 and the output bump 34 as a representative example, the connection structure of the input terminal portion 30 and the input bump 33 is similar. The anisotropic conductive film 35 will now be described. The anisotropic conductive film 35 is formed by dispersing a large number of conductive particles 35B in a binder 35A made of a thermosetting resin material. When mounting the driver 12, the anisotropic conductive film 35 and the driver 12 are set in the arrangement area of ​​the driver 12 on the array substrate 21, and in this state, the driver 12 is thermocompression-bonded by applying a load toward the array substrate 21. As a result, the terminal portions 30, 31 on the array substrate 21 side and the bumps 33, 34 on the driver 12 side are electrically connected via the conductive particles 35B. In addition, the binder 35A is thermally cured, so that the driver 12 is mechanically fixed to the array substrate 21.

[0043] 4 and 7, the multiple output terminal units 31 include a signal terminal unit 31A to which an image signal is supplied by the driver 12, a gate control terminal unit 31B to which various signals for controlling the gate drive circuit 15 are supplied by the driver 12, a switch control terminal unit (control terminal unit) 31C to which a switch signal (control signal) for controlling the switch circuit 16 is supplied by the driver 12, and a dummy terminal unit 31D. Note that in FIGS. 4 and 7, the switch control terminal unit 31C is shown shaded to distinguish it from the other terminal units 30, 31A, 31B, and 31D. Of these, the gate control terminal unit 31B is supplied with a clock signal, an initialization signal, a gate start pulse signal, etc. from the driver 12. The non-display area NAA of the array substrate 21 is provided with signal connection wiring 38 connected to the signal terminal section 31A and the switch circuit 16, gate control wiring 39 connected to the gate control terminal section 31B and the gate drive circuit 15, and switch control wiring (control wiring) 40 connected to the switch control terminal section 31C and the switch circuit 16. Each of these wirings 38 to 40 is formed using a first metal film or a second metal film. The dummy terminal section 31D is not connected to any wiring and is electrically isolated from other wirings and terminal sections.

[0044] As shown in FIG. 4, the signal terminal portion 31A, the gate control terminal portion 31B, the switch control terminal portion 31C, and the dummy terminal portion 31D are arranged in plural numbers symmetrically in the mounting area of ​​the driver 12. Similarly, the signal connection wirings 38, the gate control wirings 39, and the switch control wirings 40 are arranged in plural numbers symmetrically in the non-display area NAA. The signal connection wirings 38 connected to the signal terminal portions 31A arranged in approximately the left half of the mounting area of ​​the driver 12 in FIG. 4 are connected to the source wirings 27 arranged in approximately the left half of the display area AA in FIG. 4. The signal connection wirings 38 connected to the signal terminal portions 31A arranged in approximately the right half of the mounting area of ​​the driver 12 in FIG. 4 are connected to the source wirings 27 arranged in approximately the right half of the display area AA in FIG. 4. Of the mounting area of ​​the driver 12, a plurality of gate control wirings 39 connected to a plurality of gate control terminals 31B arranged in approximately half of the area on the left side in Fig. 4 are connected to the gate driving circuit 15 arranged on the left side of the pair of gate driving circuits 15 in Fig. 4. Of the mounting area of ​​the driver 12, a plurality of gate control wirings 39 connected to a plurality of gate control terminals 31B arranged in approximately half of the area on the right side in Fig. 4 are connected to the gate driving circuit 15 arranged on the right side of the pair of gate driving circuits 15 in Fig. 4. Note that Fig. 7 representatively illustrates the terminals 31A to 31D arranged in approximately half of the area on the left side in Fig. 4 of the mounting area of ​​the driver 12, and the wirings 38 to 40 connected to these terminals 31A to 31D.

[0045] Here, the detailed configuration of the switch circuit 16 will be described with reference to FIG. 7. As shown in FIG. 7, the switch circuit 16 has a plurality of unit switch circuits 16U arranged along its extension direction (X-axis direction). The number of unit switch circuits 16U is one-third the number of source wirings 27. Each unit switch circuit 16U has a switch control wiring 40, a signal connection wiring 38, and three switch TFTs 41-43 that are connected to the source wirings 27 and control the supply of image signals. Three switch control wirings 40 are arranged at intervals in the Y-axis direction within the formation area of ​​the switch circuit 16, and all extend along the X-axis direction. The three switch control wirings 40 are, from the bottom of FIG. 7, a first switch control wiring (first control wiring, red switch control wiring) 40α, a second switch control wiring (second control wiring, green switch control wiring) 40β, and a third switch control wiring (third control wiring, blue switch control wiring) 40γ. The signal connection wiring 38 branches into three within the area where the switch circuit 16 is formed, and each branch is arranged to intersect with each switch control wiring 40. The three switch TFTs 41 to 43 are, from right to left in FIG. 3, a first switch TFT (first switching element, red switch TFT) 41, a second switch TFT (second switching element, green switch TFT) 42, and a third switch TFT (blue switch TFT) 43. The first switch TFT 41 has a gate electrode connected to the first switch control wiring 40α and a drain electrode connected to a first source wiring (first signal wiring) 27α that supplies an image signal to a pixel electrode 25 that constitutes a red subpixel. The second switch TFT 42 has a gate electrode connected to a second switch control wiring 40β and a drain electrode connected to a second source wiring (second signal wiring) 27β that supplies an image signal to a pixel electrode 25 that constitutes a green subpixel. The third switch TFT 43 has a gate electrode connected to the third switch control line 40γ and a drain electrode connected to a third source line (third signal line) 27γ that supplies an image signal to the pixel electrode 25 that configures the blue sub-pixel. The source electrodes of each of the switch TFTs 41 to 43 are connected to three branched portions of the signal connection line 38, respectively.The number of signal connection wires 38 installed is one-third of the number of source wires 27 installed. In this way, the number of wires (signal connection wires 38) existing between the driver 12 and the switch circuit 16 can be reduced to one-third compared to the case where each source wire is directly connected to the driver 12. This makes it possible to easily route the signal connection wires 38 even when the frame of the liquid crystal panel 11 continues to become narrower.

[0046] A first image signal (red image signal) for the sub-pixels that exhibit red, a second image signal (green image signal) for the sub-pixels that exhibit green, and a third image signal (blue image signal) for the sub-pixels that exhibit blue are supplied to the signal connection wiring 38 from the driver 12 in a time-division manner. Synchronously with this, a switch signal is supplied from the driver 12 to the three switch control wirings 40. Specifically, when the driver 12 supplies the first image signal to the signal connection wiring 38, the driver 12 supplies a switch signal to the first switch control wiring 40α. This selectively turns on the first switch TFT 41 of the three switch TFTs 41-43, allowing the first image signal to be supplied to the pixel electrode 25 that constitutes the sub-pixel that exhibits red via the selected first source wiring 27α. When the driver 12 supplies the second image signal to the signal connection wiring 38, the driver 12 supplies a switch signal to the second switch control wiring 40β. As a result, the second switch TFT42 of the three switch TFTs 41 to 43 is selectively turned on, allowing the second image signal to be supplied to the pixel electrode 25 constituting the subpixel exhibiting green via the selected second source wiring 27β. At the timing when the driver 12 supplies the third image signal to the signal connecting wiring 38, the driver 12 supplies a switch signal to the third switch control wiring 40γ. As a result, the third switch TFT43 of the three switch TFTs 41 to 43 is selectively turned on, allowing the third image signal to be supplied to the pixel electrode 25 constituting the subpixel exhibiting blue via the selected third source wiring 27γ. As described above, the switch circuit 16 can switch the source wiring 27 connected to the signal connecting wiring 38 in synchronization with the timing when the driver 12 supplies the image signal to the signal connecting wiring 38.

[0047] Next, the arrangement of the terminal units 31A to 31D in the mounting area of ​​the driver 12 will be described. As shown in FIG. 7, the gate control terminal unit 31B is arranged at the end (left side in FIG. 7) of the mounting area of ​​the driver 12 in the non-display area NAA in the X-axis direction. Three gate control terminal units 31B are arranged side by side with gaps in the X-axis direction. The switch control terminal unit 31C is arranged so as to be located closer to the center of the non-display area NAA in the X-axis direction (right side in FIG. 7) than the gate control terminal units 31B. Three switch control terminal units 31C are arranged side by side with gaps in the X-axis direction. The signal terminal unit 31A is arranged so as to be located closer to the center of the non-display area NAA in the X-axis direction than the switch control terminal units 31C. The number of signal terminal units 31A is about one-third the number of source wirings 27, and they are arranged side by side with gaps in the X-axis direction. The dummy terminal portion 31D is arranged at the center in the X-axis direction in the non-display area NAA within the mounting area of ​​the driver 12. The number of dummy terminal portions 31D is determined by subtracting the number of signal terminal portions 31A, gate control terminal portions 31B, and switch control terminal portions 31C from the number of output bumps 34 of the mounted driver 12, and the dummy terminal portions 31D are arranged side by side at intervals in the X-axis direction.

[0048] As shown in FIG. 7, the plurality of signal connection wires 38 connected to the plurality of signal terminal portions 31A extend from the mounting area of ​​the driver 12 in the non-display area NAA toward the display area AA. Here, the long side dimension of the driver 12 is smaller than the short side dimension of the display area AA (see FIGS. 1 and 4). Therefore, the plurality of signal connection wires 38 are routed so as to fan out from the driver 12 side toward the display area AA side. More specifically, the plurality of signal connection wires 38 extend from the signal terminal portions 31A to be connected along the Y-axis direction toward the display area AA side (upper side in FIG. 7), cross the first side portion 12A of the driver 12, are bent, and extend along a diagonal direction relative to the X-axis and Y-axis directions toward the source wires 27 to be connected. As shown in Figure 4, the three gate control wirings 39 connected to the three gate control terminal portions 31B extend from the gate control terminal portion 31B to be connected along the Y-axis direction toward the opposite side of the display area AA (the lower side of Figure 4), then bend, extend along the X-axis direction toward the end side of the non-display area NAA, then bend, and extend along the Y-axis direction toward the gate drive circuit 15 to be connected.

[0049] 7, the three switch control terminal units 31C include a first switch control terminal unit (first control terminal unit) 31Cα connected to the first switch control wiring 40α, a second switch control terminal unit (second control terminal unit) 31Cβ connected to the second switch control wiring 40β, and a third switch control terminal unit (third control terminal unit) 31Cγ connected to the third switch control wiring 40γ. A switch signal is supplied from the driver 12 to the first switch control terminal unit 31Cα at the timing when the first image signal is supplied from the driver 12 to the signal connection wiring 38. A switch signal is supplied from the driver 12 to the second switch control terminal unit 31Cβ at the timing when the second image signal is supplied from the driver 12 to the signal connection wiring 38. A switch signal is supplied from the driver 12 to the third switch control terminal unit 31Cγ at the timing when the third image signal is supplied from the driver 12 to the signal connection wiring 38.

[0050] As shown in Fig. 7, the three switch control wires 40 extend from the switch control terminal unit 31C to be connected along the Y-axis direction toward the opposite side from the display area AA, then bend, extend along the X-axis direction toward the center of the non-display area NAA (the right side in Fig. 7), then bend, and extend along the Y-axis direction toward the display area AA, thereby crossing the first side 12A of the driver 12. The three switch control wires 40 cross the first side 12A of the driver 12, then bend, and extend along the X-axis direction toward the end of the non-display area NAA (the left side in Fig. 7) and are connected to the first end 16A of the switch circuit 16. Each switch control wire 40 is arranged so as to pass between the dummy terminal units 31D lined up along the X-axis in the mounting area of ​​the driver 12, on the way from the switch control terminal unit 31C to the first end 16A of the switch circuit 16. Specifically, the first switch control wiring 40α passes between the first dummy terminal portion (first terminal portion) 31Dα and the second dummy terminal portion (second terminal portion) 31Dβ, which are aligned along the X-axis direction in the mounting area of ​​the driver 12. The first dummy terminal portion 31Dα is disposed closer to the center in the X-axis direction in the non-display area NAA than any of the switch control terminal portions 31C. The second dummy terminal portion 31Dβ is disposed closer to the center in the X-axis direction in the non-display area NAA than the first dummy terminal portion 31Dα, with a gap therebetween. The second switch control wiring 40β passes between the second dummy terminal portion 31Dβ and the third dummy terminal portion 31Dγ, which are aligned along the X-axis direction in the mounting area of ​​the driver 12. The third switch control wiring 40γ passes between the third dummy terminal portion 31Dγ and the fourth dummy terminal portion 31Dδ, which are aligned along the X-axis direction in the mounting area of ​​the driver 12. The distance between two adjacent dummy terminal portions 31D in the X-axis direction is set to be sufficiently wider than the line width of the switch control line 40.

[0051] As described above, the switch control wiring 40 according to this embodiment is arranged so as to extend from the switch control terminal 31C across the first side 12A of the driver 12 to the first end 16A of the switch circuit 16. Therefore, compared to the conventional arrangement in which the switch control wiring extends from the switch control terminal 31C to the second end 16B of the switch circuit 16 (the end portion in the X-axis direction of the non-display area NAA) (see the switch control wiring indicated by the dashed-dotted line in FIG. 7 ), the wiring length of the switch control wiring 40 can be shortened, and it is not necessary to secure space for the switch control wiring 40 near the end of the non-display area NAA in the X-axis direction. This reduces the load on the switch control wiring 40 and enables a narrower picture frame. Furthermore, the switch control wiring 40 is arranged so as to extend between the first dummy terminal 31Dα and the second dummy terminal 31Dβ and cross the first side 12A. Although the switch control terminal portion 31C is arranged closer to the end in the X-axis direction in the non-display area NAA than the first dummy terminal portion 31Dα and the second dummy terminal portion 31Dβ, the switch control wiring 40 connected to the switch control terminal portion 31C passes between the first dummy terminal portion 31Dα and the second dummy terminal portion 31Dβ, thereby crossing the first side portion 12A and reaching the first end portion 16A of the switch circuit 16. Furthermore, since the first dummy terminal portion 31Dα and the second dummy terminal portion 31Dβ are both electrically isolated, it is possible to avoid electrical problems even if the switch control wiring 40 is short-circuited to the first dummy terminal portion 31Dα or the second dummy terminal portion 31Dβ due to a manufacturing problem.

[0052] 7, the signal terminal portion 31A according to this embodiment is located between the switch control terminal portion 31C and the first dummy terminal portion 31Dα in the X-axis direction, and multiple signal terminal portions 31A are arranged side by side with a gap in the X-axis direction. Thus, the switch control terminal portion 31C is located further toward the end of the multiple signal terminal portions 31A in the non-display area NAA than the signal terminal portion 31A located at the farthest end in the X-axis direction. Therefore, compared to the conventional case where the switch control wiring is arranged from the switch control terminal portion 31C to the second end 16B of the switch circuit 16, it is not necessary to secure space for the switch control wiring 40 closer to the end of the signal connection wiring 38 in the X-axis direction in the non-display area NAA. This is advantageous for achieving a narrower frame.

[0053] As described above, the liquid crystal display device (display device) 10 of this embodiment includes a liquid crystal panel (display panel) 11 having a main surface 11S including a display area AA where an image is displayed and a non-display area NAA surrounding the display area AA, a driver 12 attached to the non-display area NAA, a switch control terminal section (control terminal section) 31C provided in the non-display area NAA at a position overlapping with the driver 12 and connected to the driver 12, a switch circuit (first circuit section) 16 disposed between the display area AA and the driver 12 in the non-display area NAA, and a switch circuit (first circuit section) 16 provided in the non-display area NAA and connected to the switch control terminal section 31C and the switch circuit 16, respectively. and switch control wiring (control wiring) 40 that transmits a switch signal (control signal) for controlling the operation of the switch circuit 16, the driver 12 has a rectangular planar shape, and the side of the outer periphery that is closest to the display area AA is a first side 12A, the switch circuit 16 extends from the center toward the edge in a first direction along the first side 12A in the non-display area NAA, and has a first end 16A that is located at least on the center side in the first direction in the non-display area NAA, and the switch control wiring 40 is arranged so as to extend from the switch control terminal portion 31C across the first side 12A to the first end 16A of the switch circuit 16.

[0054] The switch control terminal unit 31C, which is arranged in a position overlapping with the driver 12 in the non-display area NAA of the liquid crystal panel 11, is connected to the driver 12 and receives a switch signal from the driver 12. The switch signal supplied from the driver 12 is transmitted from the switch control terminal unit 31C through a switch control wiring 40 and supplied to the switch circuit 16. The operation of the switch circuit 16 is controlled based on the switch signal supplied through the switch control wiring 40.

[0055] Here, the switch circuit 16 extends from the center toward the edge in the first direction along the first side 12A of the driver 12 in the non-display area NAA, and has a first end 16A located at least toward the center in the first direction in the non-display area NAA. In contrast, the switch control wiring 40 is arranged to extend from the switch control terminal 31C across the first side 12A to the first end 16A of the switch circuit 16. Therefore, compared to conventional arrangements in which the switch control wiring extends from the switch control terminal 31C to an end portion of the switch circuit 16 in the first direction in the non-display area NAA, the wiring length of the switch control wiring 40 can be shortened, and there is no need to secure space for the switch control wiring 40 near the end of the non-display area NAA in the first direction. This reduces the load on the switch control wiring 40 and enables a narrower picture frame. In this embodiment, the switch circuits 16 are divided into a pair and spaced apart in the X-axis direction, with the resulting free space occupied by the switch control wiring 40. However, this is not limiting. For example, the dimension provided between a pair of switch circuits 16 may be minimized so that the first end 16A of one switch circuit 16 and the first end 16A of the other switch circuit 16 are close to or in contact with each other. Alternatively, the switch control wiring 40 passing through the area of ​​one switch circuit 16 and the switch control wiring 40 passing through the area of ​​the other switch circuit 16 may be connected and shared, so that the one switch circuit 16 and the other switch circuit 16 are integrated. In other words, the "first end" described in this specification does not matter whether an end corresponding to the first end 16A is clearly recognized as the area occupied by the switch circuit 16 in a planar view. The "first end" refers to the position where the connection point between the switch circuit 16 and the switch control wiring 40 is set. Therefore, the term "first end" in this specification can be rephrased as "the connection point between the switch circuit (first circuit portion) and the control wiring." Furthermore, the "control wiring" described in this specification may have different wiring materials before and after the connection point on its wiring path, and the wiring before and after the connection point may be connected via a contact hole.Furthermore, the "control wiring" described in this specification may be made of the same wiring material before and after the connection point on the wiring path.

[0056] It also includes a first dummy terminal portion (first terminal portion) 31Dα provided in a position in the non-display area NAA that overlaps with the driver 12, and a second dummy terminal portion (second terminal portion) 31Dβ provided in a position in the non-display area NAA that overlaps with the driver 12, wherein the first dummy terminal portion 31Dα is arranged closer to the center in the first direction in the non-display area NAA than the switch control terminal portion 31C, and the second dummy terminal portion 31Dβ is arranged at a distance from the first dummy terminal portion 31Dα closer to the center in the first direction in the non-display area NAA, and the switch control wiring 40 is arranged to pass between the first dummy terminal portion 31Dα and the second dummy terminal portion 31Dβ and cross the first side portion 12A. Although the switch control terminal portion 31C is arranged closer to the end in the first direction in the non-display area NAA than the first dummy terminal portion 31Dα and the second dummy terminal portion 31Dβ, the switch control wiring 40 connected to the switch control terminal portion 31C passes between the first dummy terminal portion 31Dα and the second dummy terminal portion 31Dβ, crossing the first side portion 12A and reaching the first end portion 16A of the switch circuit 16.

[0057] The liquid crystal panel 11 also includes source wiring (signal wiring) 27 arranged in the display area AA and extending along a second direction intersecting the first direction; a signal terminal unit 31A arranged in the non-display area NAA at a position overlapping the driver 12 and connected to the driver 12; and signal connection wiring 38 arranged in the non-display area NAA, connected to the signal terminal unit 31A and the source wiring 27, and transmitting signals to be supplied to the source wiring 27. The signal terminal unit 31A is located between the switch control terminal unit 31C and the first dummy terminal unit 31Dα in the first direction, and multiple signal terminal units 31A are arranged side by side at intervals in the first direction. The signal terminal unit 31A arranged in the non-display area NAA at a position overlapping the driver 12 is connected to the driver 12 and receives signals from the driver 12. The signals supplied from the driver 12 are transmitted from the signal terminal unit 31A through the signal connection wiring 38 and supplied to the source wiring 27 in the display area AA. The switch control terminal portion 31C is located further toward the end of the signal terminal portion 31A that is located at the end of the non-display area NAA in the first direction. Therefore, compared to the conventional case where the switch control wiring is arranged so that it extends from the switch control terminal portion 31C to the end portion of the switch circuit 16 in the non-display area NAA in the first direction, it is not necessary to secure space for arranging the switch control wiring 40 closer to the end of the signal connection wiring 38 in the non-display area NAA in the first direction. This is advantageous for achieving a narrower frame.

[0058] Furthermore, the first dummy terminal portion 31Dα and the second dummy terminal portion 31Dβ are both electrically isolated dummy terminal portions 31D. Even if the switch control wiring 40 passing between the first dummy terminal portion 31Dα and the second dummy terminal portion 31Dβ is short-circuited to the first dummy terminal portion 31Dα or the second dummy terminal portion 31Dβ due to a manufacturing problem, the first dummy terminal portion 31Dα and the second dummy terminal portion 31Dβ are both electrically isolated dummy terminal portions 31D, so that electrical problems can be avoided.

[0059] The display device 31 also includes first source wiring (first signal wiring) 27α arranged in the display area AA and extending along a second direction intersecting the first direction, second source wiring (second signal wiring) 27β arranged in the display area AA and extending along the second direction, and signal connection wiring 38 provided in the non-display area NAA and transmitting signals to be supplied to the plurality of source wirings 27, and the switch control terminal section 31C includes a first switch control terminal section (first control terminal section) 31Cα and a second switch control terminal section (second control terminal section) 31Cβ, and the switch control wiring 40 includes a first The switch circuit 16 includes a first switch control wiring (first control wiring) 40α connected to the switch control terminal unit 31Cα and a second switch control wiring (second control wiring) 40β connected to the second switch control terminal unit 31Cβ, and has a first switch TFT (first switching element) 41 connected to the first source wiring 27α, the signal connecting wiring 38, and the first switch control wiring 40α, and a second switch TFT (second switching element) 42 connected to the second source wiring 27β, the signal connecting wiring 38, and the second switch control wiring 40β. The first switch TFT 41 included in the switch circuit 16 is driven in response to a switch signal being supplied from the first switch control terminal unit 31Cα via the first switch control wiring 40α, and supplies a signal transmitted by the signal connecting wiring 38 to the first source wiring 27α. The second switch TFT 42 provided in the switch circuit 16 is driven in response to a switch signal supplied from the second switch control terminal unit 31Cβ via the second switch control wiring 40β, and supplies the signal transmitted by the signal connection wiring 38 to the second source wiring 27β. In other words, the switch circuit 16 functions to distribute the signal transmitted by the signal connection wiring 38 to each source wiring 27 based on the switch signal transmitted by each switch control wiring 40.

[0060] <Embodiment 2> A second embodiment will be described with reference to Fig. 8. In this second embodiment, the arrangement of the switch control terminal portion 131C and the like is changed from the first embodiment. Note that redundant explanations of the structure, action, and effects similar to those of the first embodiment will be omitted.

[0061] As shown in Fig. 8, some of the output terminal units 131 according to this embodiment are arranged in the same row as the input terminal units 130. The detailed arrangement of the output terminal units 131 in the mounting area of ​​the driver 112 will be described. The plurality of signal terminal units 131A and dummy terminal units 131D (including the first dummy terminal unit 131Dα and the second dummy terminal unit 131Dβ) included in the output terminal unit 131 are located closer to the display area AA in the Y-axis direction than the input terminal unit 130, and are arranged in proximity to the first side 112A of the driver 112. The plurality of signal terminal units 131A include the signal terminal units 131A arranged in the positions (see Fig. 7) where the plurality of gate control terminal units 31B and switch control terminal units 31C were arranged in the first embodiment, and also include, for example, the signal terminal unit 131A located at the end (the left end in Fig. 8) in the X-axis direction in the non-display area NAA of the mounting area of ​​the driver 112. In contrast, the plurality of gate control terminal units 131B and switch control terminal units 131C included in the output terminal unit 131 are located farther from the display area AA in the Y-axis direction (second direction) than the signal terminal units 131A and dummy terminal units 131D, and are arranged side by side with the input terminal unit 130 along the X-axis direction. The switch control terminal unit 131C is arranged at the end (left side in FIG. 8) of the mounting area of ​​the driver 112 in the non-display area NAA in the X-axis direction. Three switch control terminal units 131C are arranged side by side with a gap in the X-axis direction. The gate control terminal unit 131B is arranged so as to be located closer to the center of the non-display area NAA in the X-axis direction (right side in FIG. 8) than the switch control terminal units 131C. Three gate control terminal units 131B are arranged side by side with a gap in the X-axis direction.

[0062] The three gate control wirings 139 connected to the three gate control terminal units 131B extend from the gate control terminal unit 131B to be connected along the Y axis direction toward the opposite side from the display area AA side (the lower side in FIG. 8) and are then bent, extend along the X axis direction toward the end side of the non-display area NAA and are then bent, and extend along the Y axis direction toward the gate drive circuit 15 to be connected (see FIG. 4). The three switch control wirings 140 extend from the switch control terminal unit 131C to be connected along the Y axis direction toward the display area AA side (the upper side in FIG. 8) and are then bent, extend along the X axis direction toward the center side of the non-display area NAA (the right side in FIG. 8) and are then bent, and extend along the Y axis direction toward the display area AA side, thereby crossing the first side 112A of the driver 112. The three switch control wirings 140 cross the first side 112A of the driver 112, then bend, and extend along the X-axis direction toward the end side of the non-display area NAA (the left side in FIG. 8), and are connected to the first end 16A (see FIG. 7) of the switch circuit 16. Each switch control wiring 140 is arranged so as to pass between the dummy terminal portions 131D lined up along the X-axis direction in the mounting area of ​​the driver 112, on the way from the switch control terminal portion 131C to the first end 16A of the switch circuit 16.

[0063] In this way, the switch control terminal portion 131C is disposed on the opposite side of the display area AA in the Y-axis direction from the dummy terminal portion 131D and the signal terminal portion 131A, so that no space is required for arranging the switch control terminal portion 131C on the row of the dummy terminal portion 131D and the signal terminal portion 131A. This allows for a larger number of signal terminal portions 131A to be installed, which is suitable for achieving higher definition.

[0064] As described above, according to this embodiment, the pixel includes a source wiring 27 (not shown in FIG. 8) that is arranged in the display area AA and extends along a second direction that intersects with the first direction, a signal terminal section 131A that is arranged in a position that overlaps with the driver 112 in the non-display area NAA and is connected to the driver 112, and a signal connection wiring 138 that is arranged in the non-display area NAA and is connected to the signal terminal section 131A and the source wiring 27 and transmits a signal to be supplied to the source wiring 27, and multiple signal terminal sections 131A are arranged side by side with spaces between them in the first direction, the first dummy terminal section 131Dα, the second dummy terminal section 131Dβ and the signal terminal section 131A are arranged in a row along the first direction, and the switch control terminal section 131C is arranged on the opposite side of the first dummy terminal section 131Dα, the second dummy terminal section 131Dβ and the signal terminal section 131A from the display area AA in the second direction. There is no need for space to place the switch control terminal portion 131C above the rows of the first dummy terminal portion 131Dα, the second dummy terminal portion 131Dβ, and the signal terminal portion 131A. This allows for a larger number of signal terminal portions 131A to be installed, which is suitable for achieving higher definition.

[0065] <Embodiment 3> 9 to 11, a third embodiment will be described. In this third embodiment, a touch panel function is added to a liquid crystal panel 211. Note that a redundant description of the structure, operation, and effects similar to those of the first and second embodiments will be omitted.

[0066] As shown in FIG. 9, the liquid crystal panel 211 according to this embodiment has a display function for displaying images as well as a touch panel function (position input function) for detecting an input position by a user. A touch panel pattern for realizing the touch panel function is integrated (in-cell) into the liquid crystal panel 211. This touch panel pattern is of a so-called projected capacitive type, and its detection method is a self-capacitive type. The touch panel pattern is composed of a plurality of touch electrodes (position detection electrodes) 44 arranged in a matrix on the main surface of the liquid crystal panel 211. The touch electrodes 44 are arranged in a display area AA of the liquid crystal panel 211. Therefore, the display area AA of the liquid crystal panel 211 substantially coincides with a touch area (position input area) where an input position can be detected, and the non-display area NAA substantially coincides with a non-touch area (non-position input area) where an input position cannot be detected. When a user approaches a conductive finger (position input object) to the surface (display surface) of the liquid crystal panel 211 to input a position based on the image in the display area AA of the liquid crystal panel 211 that the user is viewing, a capacitance is formed between the finger and the touch electrodes 44. As a result, the capacitance detected at the touch electrodes 44 near the finger changes as the finger approaches, and becomes different from that of the touch electrodes 44 farther away from the finger, making it possible to detect the input position based on this. Note that the specific number of touch electrodes 44 to be installed can be changed as appropriate, in addition to the number shown in FIG. 9. The touch electrodes 44 are substantially rectangular in plan view, with each side measuring approximately several millimeters. Therefore, the size of the touch electrodes 44 in plan view is much larger than a pixel (described later) and is arranged in an area spanning multiple pixels in the X-axis and Y-axis directions.

[0067] As shown in FIG. 9, a plurality of touch wirings (position detection wirings) 45 provided on the liquid crystal panel 211 are selectively connected to the plurality of touch electrodes 44. The touch wirings 45 extend along the Y-axis direction, and one end is connected to a specific touch electrode 44 among the plurality of touch electrodes 44 arranged along the Y-axis direction in the display area AA. The touch wirings 45 are made of a part of a third metal film arranged on the upper side of an insulating film arranged on the upper side of the second metal film. The touch wirings 45 may be arranged to overlap the source wirings 27 made of the second metal film. Like the first and second metal films, the third metal film is conductive by being a single-layer film made of one type of metal material or a laminated film or alloy made of different types of metal materials. Examples of materials that can be used for the third metal film include tantalum, molybdenum, titanium, and aluminum. Furthermore, an insulating film made of an inorganic or organic material is interposed between the third metal film constituting the touch wiring 45 and the first transparent electrode film constituting the touch electrode 44 (common electrode 228). In the insulating film, a contact hole for connecting the touch wiring 45 and the touch electrode 44, which are to be connected to each other, is formed at an overlapping portion of the insulating film. The liquid crystal panel 211 is provided with a touch connection wiring 46 connected to the other end of the touch wiring 45. The touch connection wiring 46 is made of a part of the third metal film. One end of the touch connection wiring 46 is connected to the other end of the touch wiring 45, and the other end is connected to the driver 212 via a touch terminal unit 231E described later. Furthermore, the touch wiring 45 is connected to a detection circuit at least via the touch connection wiring 46. The detection circuit may be provided in the driver 212 or may be provided outside the liquid crystal panel 211 via a flexible substrate 213.

[0068] As shown in FIG. 9 , the touch electrodes 44 and touch wiring 45 described above are both provided on the array substrate 221. Of these, the touch electrodes 44 are configured by dividing a common electrode 228 provided on the array substrate 221. Specifically, the common electrode 228, which is generally arranged in a solid pattern on the main surface of the array substrate 221, is provided with lattice-shaped partition openings, thereby configuring touch electrodes 44 arranged in a grid pattern in the X-axis direction and the Y-axis direction. A common potential signal related to the image display function and a touch signal (position detection signal) related to the touch panel function are supplied from the driver 212 to the touch wiring 45 in a time-division manner. The timing when the common potential signal is supplied from the driver 212 to the touch wiring 45 is the display period, and the timing when the touch signal is supplied from the driver 212 to the touch wiring 45 is the sensing period (position detection period). This common potential signal is transmitted to all touch wirings 45 at the same timing (display period), so that all touch electrodes 44 become a reference potential based on the common potential signal and function as common electrodes 228. The touch electrodes 44 have a touch panel function and also function as the above-mentioned common electrodes 228. During the display period, as explained in paragraph 0032, the pixel electrodes 25 are charged with a potential based on the image signal (see FIG. 4), and during this display period the touch electrodes 44 function as common electrodes 228.

[0069] 10, a plurality of touch terminal portions 231E connected to the touch connection wiring 46 are provided as the output terminal portion 231 in the mounting region of the driver 212 on the array substrate 221. The arrangement of the output terminal portion 231 will be described in detail below. The plurality of signal terminal portions 231A, dummy terminal portions 231D, and touch terminal portions 231E included in the output terminal portion 231 form two columns spaced apart in the Y-axis direction. The plurality of signal terminal portions 231A and dummy terminal portions 231D are aligned along the X-axis direction to form one column (hereinafter referred to as the "upper column"), and are arranged closer to the display area AA in the Y-axis direction than the column of the plurality of dummy terminal portions 231D and touch terminal portions 231E described below. The plurality of signal terminal portions 231A are arranged in the upper row at the end in the X-axis direction (left side in FIG. 10) of the non-display area NAA of the mounting area of ​​driver 212, and are arranged side by side at intervals along the X-axis direction. The plurality of dummy terminal portions 231D are arranged in the upper row at the center in the X-axis direction (right side in FIG. 10) of the non-display area NAA of the mounting area of ​​driver 212, and are arranged side by side at intervals along the X-axis direction.

[0070] The plurality of dummy terminal units 231D and touch terminal units 231E are arranged in a row (hereinafter referred to as the "lower row") at intervals along the X-axis direction, and are arranged at intervals on the opposite side of the display area AA from the row of the plurality of signal terminal units 231A. In the lower row, the plurality of touch terminal units 231E are arranged at an end side in the X-axis direction (left side in FIG. 10) of the non-display area NAA in the mounting area of ​​the driver 212, and are arranged in a row at intervals along the X-axis direction. In the lower row, the plurality of dummy terminal units 231D are arranged in a row at an interval along the X-axis direction at a center side (right side in FIG. 10) of the non-display area NAA in the mounting area of ​​the driver 212, and are arranged in a row at intervals along the X-axis direction. The positions of the plurality of signal terminal portions 231A and dummy terminal portions 231D forming an upper row and the plurality of dummy terminal portions 231D and touch terminal portions 231E forming a lower row are misaligned in the X-axis direction. The amount of misalignment in the X-axis direction between the plurality of signal terminal portions 231A and dummy terminal portions 231D forming an upper row and the plurality of dummy terminal portions 231D and touch terminal portions 231E forming a lower row is approximately half the arrangement pitch of the output terminal portions 231. In this way, the plurality of signal terminal portions 231A, dummy terminal portions 231D, and touch terminal portions 231E forming two rows are arranged in a staggered pattern overall.

[0071] As shown in FIG. 10, the plurality of gate control terminal units 231B and switch control terminal units 231C included in the output terminal unit 231 are located farther from the display area AA in the Y-axis direction than the signal terminal unit 231A, the dummy terminal unit 231D, and the touch terminal unit 231E, and are arranged side by side along the X-axis direction to form the same row as the input terminal unit 230. Note that in FIG. 10, the switch control terminal unit 231C is illustrated shaded to distinguish it from the other terminal units 230, 231A, 231B, and 231D. The switch control terminal unit 231C is arranged at the end (left side in FIG. 10) of the non-display area NAA in the X-axis direction within the mounting area of ​​the driver 212. Three switch control terminal units 231C are arranged side by side with a gap between them in the X-axis direction. The gate control terminal portion 231B is arranged to be located closer to the center in the X-axis direction (to the right in FIG. 10) in the non-display area NAA than the switch control terminal portion 231C. Three gate control terminal portions 231B are arranged side by side at intervals in the X-axis direction.

[0072] 11, the plurality of bumps 233, 234 provided on the main surface of the driver 212 facing the array substrate 221 are arranged at positions overlapping the respective terminal portions 230, 231 on the array substrate 221 side. Of the plurality of output bumps 234, the output bumps 234 overlapping the plurality of signal terminal portions 231A, dummy terminal portions 231D, and touch terminal portions 231E form two rows spaced apart in the Y-axis direction and are arranged in a staggered pattern. The plurality of input bumps 233 are arranged side by side at intervals along the X-axis direction to form one row spaced apart from the plurality of output bumps 234 arranged in a staggered pattern on the opposite side of the first side portion 212A in the Y-axis direction. Of the multiple output bumps 234, the output bumps 234 that overlap with the multiple gate control terminal portions 231B and switch control terminal portions 231C are arranged in the same row as the multiple input bumps 233 along the X-axis direction.

[0073] 10, the plurality of touch connection wirings 46 connected to the plurality of touch terminal units 231E extend from the touch terminal units 231E to be connected along the Y-axis direction toward the display area AA side (upper side in FIG. 10), pass between two signal terminal units 231A adjacent to each other in the X-axis direction, and cross the first side 212A of the driver 212. The touch connection wirings 46 are then bent and extend in diagonal directions relative to the X-axis and Y-axis directions toward the touch wiring 45 to be connected, similar to the signal connection wirings 238. Because the touch connection wirings 46 are made of a part of the third metal film, short-circuiting can be avoided even if they intersect with the signal connection wirings 238 made of the first metal film or the second metal film.

[0074] The switch control wiring 240 extends from the switch control terminal 231C to be connected along the Y-axis toward the display area AA (upper side in FIG. 10), then bends, extends along the X-axis toward the center of the non-display area NAA (right side in FIG. 10), then bends, and extends along the Y-axis toward the display area AA. The switch control wiring 240 is bent in a crank shape to pass between the staggered dummy terminals 231D and crosses the first side 212A of the driver 212. The switch control wiring 240 crosses the first side 212A of the driver 212, then bends, extends along the X-axis toward the end of the non-display area NAA (left side in FIG. 10), and is connected to the first end 216A of the switch circuit 216. This configuration allows for a larger number of signal terminals 231A, as in the second embodiment, which is advantageous for achieving higher resolution. The routing path of the gate control wiring 239 is the same as in the second embodiment.

[0075] <Embodiment 4> A fourth embodiment will be described with reference to Fig. 12 or 13. In this fourth embodiment, the number of switch control terminal units 331C installed is changed from that of the third embodiment. Note that redundant explanations of the structure, action, and effects similar to those of the third embodiment will be omitted.

[0076] As shown in FIGS. 12 and 13, two groups each consisting of a plurality of switch control terminal units 331C are provided in the mounting area of ​​the driver 312 according to this embodiment. In FIGS. 12 and 13, the switch control terminal units 331C are shown shaded to distinguish them from the other terminal units 330, 331A, 331B, 331D, and 331E. The switch control terminal units 331C constituting the first group are arranged in the same row as the plurality of signal terminal units 331A, with three of them spaced apart in the X-axis direction. That is, the three switch control terminal units 331C constituting the first group constitute the upper row of the two rows each consisting of a plurality of signal terminal units 331A, dummy terminal units 331D, and touch terminal units 331E. The three switch control terminal units 331C constituting the first group are arranged closer to the display area AA in the Y-axis direction (second direction) than the input terminal unit (third terminal unit) 330. The three switch control terminal units 331C constituting the first group are arranged closer to the center in the X-axis direction of the non-display area NAA (to the right in FIG. 12) than the dummy terminal units 331D constituting the upper row. The switch control terminal units 331C constituting the second group are arranged in the same row as the multiple input terminal units 330, and the three are arranged with a gap between them in the X-axis direction. The three switch control terminal units 331C constituting the second group are arranged closer to the end in the X-axis direction of the non-display area NAA than the gate control terminal units 331B (to the left in FIG. 12), and are located at the endmost position in the X-axis direction of the mounting area of ​​the driver 312 in the non-display area NAA.

[0077] In this embodiment, as shown in FIGS. 12 and 13 , the switch control wiring 340 is selectively provided so as to be connected to either the switch control terminal units 331C constituting the first group or the switch control terminal units 331C constituting the second group. Specifically, for example, two types of drivers 312 having different arrangements of output bumps 34 (see FIG. 11 ) that output switch signals may be selectively used as the drivers 312 mounted on the array substrate 321. In this case, regardless of the specifications of the drivers 312 mounted on the array substrate 321, either the switch control terminal units 331C constituting the first group or the switch control terminal units 331C constituting the second group are connected to the output bumps 34 that output switch signals. The group to which the switch control wiring 340 is connected is determined depending on the specifications of the drivers 312 mounted on the array substrate 321.

[0078] Specifically, when the output bump 34 that outputs a switch signal of the driver 312 is connected to the switch control terminal portion 331C that constitutes the first group, the switch control wiring 340 is provided so as to be connected to the switch control terminal portion 331C that constitutes the first group, as shown in Fig. 12. In this case, the switch control wiring 340 extends from the switch control terminal portion 331C to be connected to along the Y-axis direction toward the display area AA, and crosses the first side portion 312A of the driver 312. When the output bump 34 that outputs a switch signal of the driver 312 is connected to the switch control terminal portion 331C that constitutes the second group, the switch control wiring 340 is provided so as to be connected to the switch control terminal portion 331C that constitutes the second group, as shown in Fig. 13. In this case, the switch control wiring 340 extends from the switch control terminal unit 331C to be connected along the Y-axis direction toward the display area AA (upper side in FIG. 13), then is bent, extends along the X-axis direction toward the center of the non-display area NAA (right side in FIG. 13), then is bent, and extends along the Y-axis direction toward the display area AA. The switch control wiring 340 is bent in a crank shape so as to pass between the plurality of dummy terminal units 331D arranged in a staggered pattern and the switch control terminal units 331C that make up the first group, and then crosses the first side 312A of the driver 312.

[0079] 12, when the switch control wiring 340 is connected to the switch control terminal units 331C constituting the first group, the wiring length of the switch control wiring 340 can be shortened compared to when the switch control wiring 340 is connected to the switch control terminal units 331C constituting the second group. This reduces the load on the switch control wiring 340. In this embodiment, by providing two groups of switch control terminal units 331C on the array substrate 321, two types of drivers 312 having different configurations of output bumps 34 can be selectively mounted, thereby improving the versatility of the array substrate 321. Of the two groups of switch control terminal units 331C, the switch control terminal units 331C of the group that are not connected to the output bumps 34 that output switch signals are essentially electrically isolated, similar to the dummy terminal units 331D.

[0080] As described above, according to this embodiment, the input terminal unit (third terminal unit) 330 is provided at a position in the non-display area NAA that overlaps with the driver 312, and the switch control terminal unit 331C is disposed on the display area AA side with respect to the input terminal unit 330 in the second direction that intersects with the first direction. Compared to a case in which the switch control terminal unit 331C is disposed in a row with the input terminal unit 330 along the first direction, the wiring length of the switch control wiring 340 can be shortened. This reduces the load on the switch control wiring 340.

[0081] <Embodiment 5> Embodiment 5 will be described with reference to Fig. 14 or 15. In this embodiment 5, the planar shape of the liquid crystal panel 411 is changed from that of the above-mentioned embodiment 1. Note that redundant explanations of the structure, action, and effects similar to those of the above-mentioned embodiment 1 will be omitted.

[0082] As shown in FIG. 14 , the liquid crystal panel 411 according to this embodiment has an approximately circular planar shape as a whole. Specifically, a portion of the outer peripheral edge of the liquid crystal panel 411 is linear along the X-axis direction, while the remaining portion is arc-shaped. The arc-shaped portion of the outer peripheral edge of the liquid crystal panel 411 constitutes a variable outer shape section 411V, the outer dimensions of which change along the X-axis direction depending on the position along the Y-axis direction. The display area AA of the liquid crystal panel 411 is circular. The non-display area NAA of the liquid crystal panel 411 is approximately annular and surrounds the circular display area AA. The common electrode 428 provided on the array substrate 421 is circular and slightly larger than the display area AA, and a common wiring 429 is connected to a portion of the outer peripheral edge. A driver 412 and a flexible substrate 13 (not shown in FIGS. 14 and 15 ) are mounted on the liquid crystal panel 411 near the linear portion of the outer peripheral edge.

[0083] As shown in FIG. 14, a pair of gate drive circuits (first circuit units) 415 are provided to sandwich the display area AA from both sides in the X-axis direction. The gate drive circuits 415 are provided in a semicircular band-like range extending along the outer shape of the variable outer shape unit 411V, and extend from the center toward the ends in the X-axis direction. The gate drive circuits 415 are symmetrical with respect to an axis of symmetry along the X-axis direction. One end of the gate drive circuit 415 is a first end 415A located close to and spaced from the driver 412 in the Y-axis direction and located near the center of the non-display area NAA in the X-axis direction. The other end of the gate drive circuit 415 is a second end 415B located on the opposite side from the driver 412 in the Y-axis direction and located near the center of the non-display area NAA in the X-axis direction. The gate drive circuit 415 is arranged so that its center in its extension direction is located near the end of the non-display area NAA in the X-axis direction. The liquid crystal panel 411 according to this embodiment does not include the switch circuit 16 (see FIG. 4) described in the first embodiment.

[0084] The arrangement of the terminals 431A, 431B, and 431D in the mounting area of ​​the driver 412 will be described. As shown in FIG. 15, the gate control terminal (control terminal) 431B is arranged at the end of the mounting area of ​​the driver 412 in the X-axis direction in the non-display area NAA. Note that in FIG. 15, the gate control terminal 431B is shown shaded to distinguish it from the other terminals 430, 431A, and 431D. Three gate control terminals 431B are arranged side by side with gaps in the X-axis direction. A clock signal, an initialization signal, a gate start pulse signal, and the like are supplied to the gate control terminal 431B from the driver 412. The clock signal, the initialization signal, and the gate start pulse signal are all control signals for controlling the operation of the gate drive circuit 415. The signal terminal 431A is arranged closer to the center of the non-display area NAA in the X-axis direction than the gate control terminal 431B. The number of signal terminal portions 431A is equal to the number of source wirings 427, and they are arranged side by side at intervals in the X-axis direction. The dummy terminal portion 431D is arranged at the center of the mounting area of ​​the driver 412 in the non-display area NAA in the X-axis direction. The number of dummy terminal portions 431D is determined by subtracting the number of signal terminal portions 431A and gate control terminal portions 431B from the number of output bumps 34 of the mounted driver 412, and they are arranged side by side at intervals in the X-axis direction. Note that the liquid crystal panel 411 according to this embodiment does not include the switch circuit 16 as described above, and therefore does not include the switch control terminal portion 31C (see FIG. 7) described in the first embodiment.

[0085] As shown in FIG. 15 , the signal connection wirings 438 connected to the signal terminal units 431A extend from the signal terminal units 431A to be connected along the Y-axis direction toward the display area AA (upper side of FIG. 15 ) and cross the first side 412A of the driver 412, then bend and extend diagonally with respect to the X-axis and Y-axis directions toward the source wirings 427 to be connected. The signal connection wirings 438 are directly connected to the source wirings 427. The signal connection wirings 438 include signal connection wirings 438 that intersect with the gate drive circuit 415 and gate control wirings (control wirings) 439 on their way from the signal terminal units 431A to the source wirings 427. The signal connection wirings 438 are made of a third metal film arranged above an insulating film arranged above a second metal film. In contrast, the wiring and circuit elements constituting the gate drive circuit 415 are formed using a first metal film, a second metal film, a semiconductor film, etc., and do not use a third metal film. Similarly, the gate control wiring 439 is formed using the first metal film and the second metal film, but does not use the third metal film. Therefore, the signal connection wiring 438, which intersects with the gate drive circuit 415 and the gate control wiring 439, is prevented from shorting with the wiring and circuit elements constituting the gate drive circuit 415 and the gate control wiring 439. Like the first and second metal films, the third metal film is conductive by being a single-layer film made of one type of metal material or a laminated film or alloy made of different types of metal materials. Examples of materials used for the third metal film include tantalum, molybdenum, titanium, and aluminum. An insulating film made of an inorganic material is interposed between the third metal film constituting the signal connection wiring 438 and the first transparent electrode film constituting the common electrode 428. Since the liquid crystal panel 411 according to this embodiment does not include the switch control terminal unit 31C as described above, the switch control wiring 40 (see FIG. 7 ) described in the first embodiment is also not included.

[0086] 15, the three gate control wirings 439 are arranged so as to take two paths from each gate control terminal portion 431B to the first end 415A of the gate drive circuit 415. The three gate control wirings 439 include a first gate control wiring (first control wiring) 439α and a second gate control wiring (second control wiring) 439β that take a first path from each gate control terminal portion 431B to the first end 415A of the gate drive circuit 415, and a third gate control wiring (third control wiring) 439γ that takes a second path from each gate control terminal portion 431B to the first end 415A of the gate drive circuit 415. The three gate control terminal portions 431B include a first gate control terminal portion (first control terminal portion) 431Bα connected to a first gate control wiring 439α, a second gate control terminal portion (second control terminal portion) 431Bβ connected to a second gate control wiring 439β, and a third gate control terminal portion (third control terminal portion) 431Bγ connected to a third gate control wiring 439γ.

[0087] 15, the first gate control wiring 439α and the second gate control wiring 439β each extend from the gate control terminal portions 431Bα, 431Bβ to be connected along the Y-axis direction toward the opposite side from the display area AA side (the lower side in FIG. 15), then bend, extend along the X-axis direction toward the center of the non-display area NAA, then bend, and extend along the Y-axis direction toward the display area AA side, thereby crossing the first side 412A of the driver 412. The first gate control wiring 439α and the second gate control wiring 439β each cross the first side 412A of the driver 412, then bend, extend along the X-axis direction toward the end side of the non-display area NAA, and are connected to a first end 415A of the gate drive circuit 415. The first gate control wiring 439α and the second gate control wiring 439β are arranged so as to pass between the dummy terminal portions 431D that are lined up along the X-axis direction in the mounting area of ​​the driver 412 on the way from the gate control terminal portions 431Bα and 431Bβ to be connected to the first end 415A of the gate drive circuit 415. In this way, the first paths that the first gate control wiring 439α and the second gate control wiring 439β take from the gate control terminal portions 431Bα and 431Bβ to be connected to the first end 415A of the gate drive circuit 415 are generally similar to the paths of the switch control wirings 40 described in the first embodiment. Therefore, according to the present embodiment, as in the first embodiment, it is possible to reduce the load on the gate control wiring 439 and to achieve a narrower frame.

[0088] 15, the third gate control wiring 439γ extends from the third gate control terminal portion 431Bγ along the Y-axis direction toward the display area AA (upper side of FIG. 15), crosses the first side portion 412A of the driver 412, is bent, and extends along the X-axis direction toward the center of the non-display area NAA. The third gate control wiring 439γ is bent again and extends along the Y-axis direction toward the display area AA, then bent again, extends along the X-axis direction toward the edge of the non-display area NAA, and is connected to the first end 415A of the gate drive circuit 415. In addition, the power supply wiring 436 extends along the Y-axis direction from the power supply terminal portion 432B included in the flexible substrate terminal portion 432 toward the display area AA, then is bent, extends along the X-axis direction toward the center of the non-display area NAA, and then extends following the third gate control wiring 439γ to be connected to the first end 415A of the gate drive circuit 415.

[0089] As described above, according to this embodiment, the liquid crystal panel 411 has a variable outer shape portion 411V whose outer dimensions in the first direction change depending on its position in the second direction intersecting the first direction, and the gate drive circuit (first circuit portion) 415 extends in a manner that follows the outer shape of the variable outer shape portion 411V. In the non-display area NAA of the liquid crystal panel 411, it is difficult to secure sufficient space for arranging wiring and the like between the outer edge of the variable outer shape portion 411V and the gate drive circuit 415. In this regard, the gate control wiring (control wiring) 439 is arranged from the gate control terminal portion (control terminal portion) 431B across the first side portion 412A to the first end 415A of the gate drive circuit 415. Therefore, it is not necessary to secure space for arranging the gate control wiring 439 between the outer edge of the variable outer shape portion 411V and the gate drive circuit 415. This allows for a narrower frame, which is advantageous for miniaturizing the liquid crystal panel 411.
