Summary of the Invention

Problems to be Solved by the Invention

[0004] Although the sensor electrodes of the touch sensor have various shapes, a mesh-shaped or reticulated electrode surrounding the contour of the sub-pixel is advantageous in terms of reducing resistance because it can be formed of metal. On the other hand, the sensor electrode is covered with an overcoat layer formed of an organic resin material, but there is a problem that the organic resin material cannot be uniformly applied due to the step formed by the mesh-shaped electrode pattern.

[0005] One embodiment of the present invention aims to provide a display device with improved reliability.

[0013] <First Embodiment> In this embodiment, the structure of the display device 10 according to one embodiment is shown. FIG. 1 is a diagram showing the display area of the display device and the arrangement of the touch sensor according to this embodiment.

[0014] 1. Overall Structure The display device 10 has a substrate 102, and a display area 104, a peripheral area 106, a plurality of pixels 108, a touch sensor 112, mounting pads 114, inspection pads 116, and a counter substrate 118 are provided on the substrate 102.

[0015] The display device 10 includes a display area 104 and a peripheral area 106 surrounding it. In the display area 104, a plurality of pixels for display are arranged. The touch sensor 112 is arranged so as to overlap the display area 104. In the peripheral area 106, mounting pads 114, inspection pads 116, sensor wirings 120 connecting the sensor electrodes of the touch sensor, and other wirings 122 are arranged. Although omitted in FIG. 1, the display device 10 further has a counter substrate 118 that is paired with the substrate 102 so as to overlap the display area 104 and the peripheral area 106, as shown by a dotted line in FIG. 4 described later.

[0016] 1-1. Pixel The display area 104 includes at least one pixel, for example, includes a plurality of pixels arranged in the X-axis direction and the Y-axis direction. FIG. 2 shows the arrangement of pixels in the display area 104. As shown in FIG. 2, the plurality of pixels 108 are arranged in the display area 104, for example, in the row direction (X direction) and the column direction (Y direction). The pixel 108 includes a plurality of sub-pixels 110. FIG. ② shows an example in which the pixel 108 includes sub-pixels 110-1, sub-pixels 110-2, and sub-pixels 110-3. Each sub-pixel corresponds to each color for color display, and a light-emitting element 110E that exhibits a different emission color is used. For example, a light-emitting element 110E-B that emits blue light is used for the sub-pixel 110-1, a light-emitting element 110E-G that emits green light is used for the sub-pixel 110-2, and a light-emitting element 110E-R that emits red light is used for the sub-pixel 110-3. For the light-emitting element 110E, for example, an organic electroluminescence (EL) element may be used. It should be noted that there is an error in the original text where "図2には、画素108が、副画素110-1、副画素110-2、副画素110-3を含む例を示す。" is written as "図2には、画素108が、副画素110-1、副画素110-2、副画素110-3を含む例を示す。" in Japanese, and the translated text has been corrected accordingly. Also, "図2" is written as "図②" in the original text, which is also an error and has been corrected in the translation.

[0017] 1-2. Pixel Circuit The light-emitting element E is electrically connected to a transistor provided in each sub-pixel. Figure 3 shows the circuit diagram of sub-pixel 110-1. The pixel circuit 200 of sub-pixel 110-1 includes a selection transistor 210, a drive transistor 220, a capacitor 230, and a light-emitting element 110E-B.

[0018] The selection transistor 210 is connected to a gate line 212 and a data line 214. Specifically, the gate line 212 is connected to the gate of the selection transistor 210. The data line 214 is connected to the source of the selection transistor 210. The selection transistor 210 functions as a switch to select whether or not to input a data signal (video signal Vs) to the pixel circuit 200. The drain of the selection transistor 210 is connected to the gate of the drive transistor 220 and to the capacitor 230.

[0019] The drive transistor 220 is connected to the anode power line 222, the light-emitting element 110E-B, and the capacitor 230. Specifically, the anode power line 222 is connected to the drain of the drive transistor 220. The light-emitting element 110E-B is connected to the source of the drive transistor 220. The capacitor 230 is connected between the gate and source of the drive transistor 220. The drive transistor 220 controls the amount of current flowing to the light-emitting element 110E-B. A high-potential power supply voltage (PVDD) is applied to the anode power line 222.

[0020] Capacitor 230 holds the data signal input via selection transistor 210. A voltage corresponding to the data signal held in capacitor 230 is applied to the gate of drive transistor 220. This controls the amount of current flowing through drive transistor 220 according to the data signal.

[0021] The light-emitting element 110E-B is connected between the drive transistor 220 and the cathode power line 224. Specifically, the anode of the light-emitting element 110E-B is connected to the source of the drive transistor 220. That is, the anode of the light-emitting element 110E-B is connected to the anode power line 222 via the drive transistor 220. The cathode of the light-emitting element 110E-B is connected to the cathode power line 224. A low potential power supply voltage (PVSS) is applied to the cathode power line 224.

[0022] In the pixel circuit 200, when the selection transistor 210 is turned ON, a data signal is input from the data line 214. The voltage corresponding to the input data signal is held by the capacitor 230. Subsequently, during the light emission period, the gate of the drive transistor 220 is controlled by the voltage held by the capacitor 230, and a current corresponding to the data signal flows through the drive transistor 220. When current flows through the light-emitting element 110E, the light-emitting element 110E-B emits light with a brightness corresponding to the amount of current.

[0023] The signals supplied to the pixel circuit 200 can be electrically connected to and supplied to a drive circuit provided outside the substrate 102, or to a drive circuit provided in the peripheral region 106. An integrated circuit (IC) can be used for the external drive circuit.

[0024] The driver IC can be mounted on the substrate 102, for example, by a chip-on-film (COF) using an anisotropic conductive film (ACF). For example, it can be mounted using a film-on-glass (FOG) with a wiring board mounted using an anisotropic conductive film, via mounting pads 114 provided in the peripheral region 106.

[0025] 1-3. Touch Sensor 1-3-1. Sensor Block The touch sensor 112 is arranged in the display area 104 so as to overlap with multiple pixels 108. The touch sensor 112 can be divided into multiple sensor blocks 124. The multiple sensor blocks 124 can be arranged in the display area 104 in a first direction and in a second direction intersecting the first direction. Each of the multiple sensor blocks 124 is arranged with multiple sensor electrodes 126 that constitute the touch sensor 112. The sensor blocks 124 overlap with multiple pixels 108. In the example shown in Figure 1, the multiple sensor blocks 124-1 to 124-16 are arranged in the row direction (X direction) and column direction (Y direction) in the display area 104, and each of the sensor blocks 124-1 to 124-16 is arranged with the sensor electrodes 126 described later.

[0026] Each sensor electrode 126 is connected to a different sensor wiring 120 for each sensor block 124. For example, as shown in Figure 5A later, the sensor electrode 126-1 located in sensor block 124-1 is directly or electrically connected to sensor wiring 120-1, and the sensor electrode 126-3 located in sensor block 124-3 adjacent to sensor block 124-1 is directly or electrically connected to sensor wiring 120-3. Furthermore, for example, the sensor electrode 126-16 located in sensor block 124-16 adjacent to sensor block 124-1 is directly or electrically connected to sensor wiring 120-16, and the sensor electrode 126-14 located in sensor block 124-14 adjacent to sensor block 124-16 or sensor block 124-3 is directly or electrically connected to sensor wiring 120-14.

[0027] The sensor wiring 120 is connected to the sensor electrode 126 in the display area 104, routed through the peripheral area 106, and connected to the mounting pad 114. The connection between the sensor wiring 120 and the mounting pad 114 may be an electrical connection via multiple wires or contact pads. The mounting pad 114 is electrically connected to an external drive circuit and can supply signals from the external drive circuit to the sensor wiring 120.

[0028] The drive circuit for driving the sensor electrode 126 can use a drive IC, similar to the external drive circuit for the pixel 108. The sensor electrode 126 is electrically connected to the drive IC via a mounting pad 114 that is electrically connected to the sensor wiring 120. The mounting pad 114 and the drive IC can be the aforementioned FOG or COF. The mounting pad 114 is connected to a test pad 116 used for testing the sensor electrode 126. The connection between the mounting pad 114 and the test pad 116 may be an electrical connection via multiple wires.

[0029] 1-3-2. Cross-sectional structure Here, referring to Figure 4, the structure of the display area 104 including the touch sensor 112 and the surrounding area 106 in end view will be described. A schematic end view along the dashed line A1-A5 shown in Figure 1 is shown. In the following, explanations of configurations identical to those in Figures 1 to 3 may be omitted.

[0030] The display device 10 has a substrate 102, which can be made of, for example, glass, quartz, or an organic resin. When an organic resin substrate is used, the substrate 102 can be flexible.

[0031] An undercoat 156 can be provided on the substrate 102. The undercoat 156 can prevent contamination from the substrate 102, and can be made of, for example, an inorganic insulating material. The inorganic insulating material can be, for example, silicon nitride, silicon oxide, or composites thereof.

[0032] An insulating film 158 can be provided on top of the undercoat 156. The insulating film 158 in the display area 104 can function as a gate insulating film for a transistor, which is provided when a drive circuit is present in the pixel 108 and the surrounding area. The insulating film 158 can be made of the same material as the undercoat 156.

[0033] On the insulating film 158, a signal line 172 can be provided in the display area 104, and wirings 138-1 and 138-2 can be provided in the peripheral area 106. Signals supplied to each pixel 108 from the aforementioned peripheral area drive circuit or external drive circuit are transmitted via the signal line 172. Alternatively, the signal line 172 can also function as a power line supplying a constant potential to each pixel 108. Wiring 138-1 is located between the sensor wiring 120 and the mounting pad 114, and can electrically connect the sensor electrode 126 and the terminal wiring 140-1. Wiring 138-2 is located between the mounting pad 114 and the inspection pad 116, and can constitute the wiring 122 shown in Figure 1. Wiring 138-2 can electrically connect the mounting pad 114 and the inspection pad 116. For the signal line 172 and wiring 138, materials mainly composed of titanium, aluminum, copper, molybdenum, etc., can be used, and these can be used in a single layer or in a laminated form.

[0034] An interlayer film 160 can be provided on top of the signal line 172, wiring 138-1, wiring 138-2, and insulating film 158, so as to cover the signal line 172, wiring 138-1, and wiring 138-2. The interlayer film 160 can also function as a planarizing film for the signal line 172. The interlayer film 160 can be made of the same material as the underlayer film 156.

[0035] A contact pad 162 and terminal wirings 140-1 and 140-2 can be provided on the interlayer film 160. The contact pad 162 is located on wiring 138-1 and is positioned between sensor wiring 120 and wiring 138-1. The contact pad 162 can be used to connect sensor wiring 120 and wiring 138-1. Terminal wiring 140-1 is located between sensor wiring 120 and mounting pad 114 and functions as mounting pad 114 by being exposed from the planarization layer 174H. Terminal wiring 140-1 can function as wiring that transmits signals between an external drive circuit and the touch sensor 112 shown in Figure 1. Terminal wiring 140-2 is located between wiring 138-2 and inspection pad 116 and can constitute wiring 122 shown in Figure 1. Terminal wiring 140-2 functions as inspection pad 116 by being exposed from the planarization layer 174H. Terminal wiring 140-1 and terminal wiring 140-2 may have a single-layer or multi-layer structure. For example, terminal wiring 140-1 and terminal wiring 140-2 may have a three-layer structure of titanium (Ti), aluminum (Al), and titanium (Ti); a five-layer structure of molybdenum tungsten (MoW), Ti, Al, Ti, and ITO (Indium Tin Oxide); or a four-layer structure of Mo, Al, Mo, and ITO.

[0036] An insulating layer 142 can be provided on top of the contact pad 162. The insulating layer 142 is located between the stepped portion 136-1 and the stepped portion 136-2. The insulating layer 142 covers the edge of the contact pad 162. The insulating layer 142 can be formed in the same way as the flattening layer 174H described later, and the same material as the flattening layer 174H can be used.

[0037] A planarization layer 174 can be provided in the display area 104 on the interlayer film 160 and signal lines 172. Furthermore, stepped portions 136-1 and 136-2 are provided on the interlayer film 160 in the peripheral area 106. Stepped portions 136-1 and 136-2 are positioned between the pixel 108 located in the display area 104 and the mounting pad 114 located in the peripheral area 106. Stepped portion 136-1 is positioned between the pixel 108 and stepped portion 136-2. Stepped portion 136-2 is provided on the interlayer film 160 with overlap with the wiring 138-1. Stepped portion 136-2 is positioned between stepped portion 136-1 and the mounting pad 114.

[0038] The stepped portion 136-1 is provided so as to surround the display area 104. The stepped portion 136-1 can be constructed as a laminated structure. For example, as shown in Figure 4, the stepped portion 136-1 is composed of a laminated structure of a planarization layer 174D1 and an insulating film 170. The film thickness or height of the stepped portion 136-1 in end view is the sum of the film thicknesses of the planarization layer 174D1 and the insulating film 170. The planarization layer 174D1 in the stepped portion 136-1 can be formed by removing the planarization layer 174 along the outer circumference of the display area 104. The planarization layer 174D1 formed by this removal forms a step on the substrate 102. The insulating film 170 is laminated on the planarization layer 174D1 that has formed the step, and the stepped portion 136-1 is formed. In this way, the stepped portion 136-1, whose film thickness or height is the sum of the laminated films, is a taller structure compared to other structures on the substrate 102. Therefore, the stepped portion 136-1 allows the first organic insulating layer 180, which will be described later, to cover the display area 104 to be kept within the display area 104.

[0039] The stepped portion 136-2 is provided so as to surround the stepped portion 136-1. The stepped portion 136-2 can be formed in the same way as the stepped portion 136-1. The stepped portion 136-2 can be constructed by laminating a planarization layer 174D2 and an insulating film 170, for example, as shown in Figure 4. The planarization layer 174D2 can be formed from the planarization layer 174. The planarization layer 174D2, formed along the outer circumference of the planarization layer 174, forms a step on the substrate 102. The insulating film 170 is laminated on the planarization layer 174D1 with the step formed, and the stepped portion 136-2 is formed. By forming the stepped portion 136-2 in this way, the overcoat layer 168 can be kept within the stepped portion 136-2. As a result, the mounting pad 114 is not covered by the overcoat layer 168, and can be smoothly connected to a driving IC such as a COF without the process of removing the overcoat layer 168.

[0040] Furthermore, a planarization layer 174H continuous with the stepped portion 136-2 can be provided on the wiring 138. The planarization layer 174H can be formed simultaneously with the stepped portion 136-2. For example, the planarization layer 174 of the film forming the stepped portion 136-2 can be provided up to the terminal wiring 140-1, a full-tone mask can be placed on the planarization layer 174 corresponding to the stepped portion 136-2, and a half-tone mask can be placed from the end of the planarization layer 174 up to the terminal wiring 140-1. Exposure, development, and firing can then form the planarization layer 174H. A half-tone mask is a photomask with less uniform and lower light transmittance compared to a full-tone mask.

[0041] Here, the terminal wiring 140-1, which is positioned beneath the planarization layer 174H, has a portion exposed from the planarization layer 174H, as described above, and can be used as a terminal electrode for mounting pad 114. Similarly, the terminal wiring 140-2, which is positioned beneath the planarization layer 174H, also has a portion exposed from the planarization layer 174H, as described above, and can be used as a terminal electrode for inspection pad 116.

[0042] The same materials as those used for signal lines 172 and wiring 138 can be used for terminal wiring 140-1 and terminal wiring 140-2. Furthermore, the planarization layer 174 and insulating film 170 can be made from photosensitive organic resin materials containing acrylic resin, polysiloxane, polyimide, polyester, etc., and can function as organic insulating layers. Additionally, the insulating layers 113 and 115 can be made from photosensitive organic resin materials containing epoxy resin, acrylic resin, etc.

[0043] Furthermore, an insulating film 170 can be provided on the planarization layer 174. Although the shape of the insulating film 170 is not shown in detail in Figure 4, the insulating film 170 may have structures that function as partition layers and spacers 170S. The partitions may have the function of defining pixels 108, and the spacers 170S may have the function of supporting a fine mask used in the manufacturing process of the light-emitting element 110E of the pixels 108, such as the deposition process. The partition layer is arranged to cover the electrode ends of the light-emitting element 110E provided on the pixels 108. The spacers 170S can be placed on the partition layer.

[0044] The partition layer and spacer 170S can be formed from the insulating film 170. For example, a resin film can be formed on the planarization layer 174, and an SPC mask including a full-tone mask and a half-tone mask can be used to create a spacer 170S with a thicker film thickness and a partition layer with a thinner film thickness from the insulating film 170. The spacer 170S and partition layer can be made from organic resin materials such as epoxy resin or acrylic resin used for the insulating film 170.

[0045] A sealing layer 166 is provided on the insulating film 170 and in the region surrounded by stepped portions 136-1 and 136-2 in a plan view. The sealing layer 166 has multiple insulating layers, each of which can be provided with a different function. For example, as shown in Figure 4, the sealing layer 166 has a first inorganic insulating layer 178, a first organic insulating layer 180, and a second inorganic insulating layer 182.

[0046] The region enclosed by the stepped portion 136-1 and the stepped portion 136-2 includes the display area 104, and when an organic EL element is used for the pixel 108, the first inorganic insulating layer 178 covers this region, thereby suppressing the penetration of impurities into the organic EL element. For example, an inorganic compound such as silicon oxide or silicon nitride can be used for the first inorganic insulating layer 178.

[0047] A first organic insulating layer 180 is provided on the first inorganic insulating layer 178 in the region surrounded by the stepped portion 136-1 in a planar view. The first organic insulating layer 180 is provided along the stepped portion 136-1 so as not to extend beyond the planarization layer 111 or the stepped portion 136-1. Furthermore, the first organic insulating layer 180 can planarize the area over the pixels 108, and if a light-emitting element 110E is provided on the pixels 108, it can protect the light-emitting element 110E from impurities. The first organic insulating layer 180 can be made of the same material as the insulating film 170.

[0048] A second inorganic insulating layer 182 can be provided on the first organic insulating layer 180 in the region surrounded by stepped portions 136-1 and 136-2 in a plan view. The second inorganic insulating layer 182 contacts the first inorganic insulating layer 178 in the region outside the first organic insulating layer. As a result, the first inorganic insulating layer 178 and the second inorganic insulating layer 182 cover the stepped portion 136-1 and extend to the outside of the stepped portion 136-1. With this structure, the first inorganic insulating layer 178 and the second inorganic insulating layer 182 can seal the first organic insulating layer 180. The second inorganic insulating layer 182 can be made of an inorganic compound such as silicon nitride, for example.

[0049] The multiple different types of films, such as the first organic insulating layer 180 and the second inorganic insulating layer 182 described above, can flatten the pixels 108 and protect the light-emitting elements 110E provided on the pixels 108 from impurities, so that structures such as touch sensors 112 can be provided on the pixels 108 in the display area 104.

[0050] A sensor electrode 126 can be provided on the second inorganic insulating layer 182 in the display area 104. The sensor electrode 126 can be formed using a metallic material. Examples of metallic materials include molybdenum and aluminum (zero-valent metals). The sensor electrode 126 can use a laminated structure, for example, a Ti, Al, Ti laminated structure or a Mo, Al, Mo laminated structure can be used.

[0051] Furthermore, sensor wiring 120, which connects to the sensor electrode 126, is provided on the sealing layer 166. Specifically, the sensor wiring 120 is provided on the second inorganic insulating layer 182 of the sealing layer 166. The sensor wiring 120 extends over the stepped portion 136-1 to the contact pad 162 located between the stepped portion 136-1 and the stepped portion 136-2 in order to connect to the wiring 138-1 via the contact pad 162. The sensor wiring 120 can be made of the same material as the sensor electrode 126.

[0052] Furthermore, an overcoat layer 168 is provided on the sensor electrode 126 and sensor wiring 120, covering them. The overcoat layer 168 also extends over the contact hole 135. The overcoat layer 168 is provided in the region surrounded by the stepped portion 136-2 in a plan view. The overcoat layer 168 can be made of the same material as the first organic insulating layer 180.

[0053] An opposing substrate 118 can be provided on top of the overcoat layer 168. In Figure 4, an example is shown where the opposing substrate 118 is arranged to overlap with the overcoat layer 168, but it can be placed on top of a structure provided on the substrate 102. The opposing substrate 118 can be made of a film or glass that has the function of a polarizing plate. The opposing substrate 118 also has the function of protecting the structure provided on the substrate 102, such as a pixel 108 or a touch sensor 112. Furthermore, when bonding the opposing substrate 118 and the substrate 102, an adhesive layer 169 can be used between the opposing substrate 118 and the substrate 102. An adhesive can be used for the adhesive layer 169. For the adhesive, an adhesive with a refractive index close to that of the material of the opposing substrate 118, such as OCA (Optical Clear Adhesive), can be used. By processing such an adhesive on the surface facing the structure on the substrate 102, the opposing substrate 118 and the substrate 102 can be bonded together using the adhesive layer 169.

[0054] 1-3-3. Sensor electrodes Referring to Figure 5A, the sensor electrode 126 used in the touch sensor 112 will be described. Figure 5A is a schematic diagram showing the arrangement of sensor electrodes in a display device according to one embodiment of the present invention, and is the portion 300 enclosed by the dashed line in Figure 1, and is an enlarged view of a portion of the multiple sensor blocks 124-1, sensor block 124-3, sensor block 124-14, and sensor block 124-16.

[0055] The sensor electrode 126 is linear and formed by a continuous linear pattern. Preferably, the sensor electrode 126 is continuous within the sensor block 124 and does not include any electrically floating patterns. In the example shown in Figure 5A, sensor electrode 126-1 is located in sensor block 124-1 and is continuous within sensor block 124-1. Linear sensor electrode 126-3 is located in sensor block 124-3 and is continuous within sensor block 124-3. Sensor electrode 126-16 is located in sensor block 124-16 and is continuous within sensor block 124-16. Sensor electrode 126-14 is located in sensor block 124-14 and is continuous within sensor block 124-14.

[0056] Sensor electrodes 126 located on different sensor blocks 124 are separated from each other and not connected. In the example shown in Figure 5A, sensor electrodes 126-1, 126-3, 126-14, and 126-16 located on each of the sensor blocks 124-1, 124-3, 124-14, and 124-16 are separated from each other and not continuous. Sensor electrodes 126-1 and 126-3 located on adjacent sensor blocks 124-1 and 124-3 are separated between sensor blocks 124-1 and 124-3. Sensor electrodes 126-1 and 126-16 located on adjacent sensor blocks 124-1 and 124-16 are separated between sensor blocks 124-1 and 124-16. Sensor electrodes 126-3 and 126-14, located on adjacent sensor blocks 124-3 and 124-14, are spaced apart between sensor blocks 124-3 and 124-14. Sensor electrodes 126-16 and 126-14, located on adjacent sensor blocks 124-16 and 124-14, are spaced apart between sensor blocks 124-16 and 124-14.

[0057] The sensor electrodes 126, together with sensor electrodes 126 located on other sensor blocks 124 that are spaced apart from each other, can surround the outer periphery of pixels 108 facing the boundary of sensor block 124. In the example shown in Figure 5A, multiple pixels 108B face the boundary 124B between sensor block 124-1 and sensor block 124-16. The outer periphery of the multiple pixels 108B is surrounded by sensor electrodes 126 located on sensor blocks 124-1 and sensor blocks 124-16. In this case, the sensor electrodes 126 located on sensor block 124-16 have ends facing sensor block 124-1. The sensor electrodes 126-1 located on sensor block 124-1 have portions that are continuous with respect to sensor block 124-16. Pixels 108B facing the boundary of sensor block 124 are not surrounded by continuous sensor electrodes 126, and as a result, the sensor electrodes 126 between sensor blocks 124 are spaced apart.

[0058] The sensor electrode 126 allows the position of the cut portion 184 in the pixel 108 to be repeatedly provided at the same position in multiple pixels 108. In the example shown in Figure 5A, the positions of the cut portions 184-1 and 184-2 in the pixel 108 are repeated in multiple sensor blocks 124.

[0059] Next, the configuration of the sensor electrode 126 will be explained with reference to Figure 5B. Figure 5B is a schematic diagram showing the configuration of the sensor electrode of a display device according to one embodiment of the present invention. Figure 5B shows an enlarged view of the portion 320 enclosed by the dashed line in Figure 5A.

[0060] The sensor electrode 126 is formed in a thin, linear pattern and surrounds the outer periphery of at least one pixel 108. In the sensor block 124, the sensor electrode 126 extends along the boundaries of multiple pixels 108. The sensor electrode 126 further extends along the boundaries of multiple sub-pixels 110. The sensor electrode 126 includes a sensor electrode 126S that extends along the boundaries of multiple sub-pixels 110 and a sensor electrode 126B that extends along the boundaries of multiple sub-pixels 110. The sensor electrode 126S and the sensor electrode 126B are connected and continuous in at least a portion of the area.

[0061] In the example shown in Figure 5B, the sensor electrode 126S surrounds the outer periphery of pixel 108 and extends along the boundary between pixel 108-1 and pixel 108-2. The sensor electrode 126B extends along the boundaries between sub-pixels 110-1, 110-2, and 110-3. The sensor electrode 126 is composed of sensor electrode 126S and sensor electrode 126B, and sensor electrodes 126S and 126B are partially connected and continuous at each pixel 108.

[0062] The sensor electrode 126 is arranged to overlap with multiple pixels 108, but by surrounding the outer periphery of the pixels 108 and positioning it along the boundary of the sub-pixels 110, it is possible to display an image such as an icon on the pixels 108 while simultaneously sensing the presence or absence of a touch using the touch sensor 112.

[0063] The sensor electrode 126 has at least one cut-off portion 184 at the boundary of a plurality of subpixels 110. At least one cut-off portion 184 is located at the boundary of adjacent subpixels 110. Preferably, the cut-off portion 184 is located along the inner edge of the sensor electrode 126 surrounding the outer periphery of the pixel 108. Preferably, the cut-off portion 184 is located at the boundary between sensor electrode 126S and sensor electrode B. In the example shown in Figures 5A and 5B, subpixels 110-1 and 110-2 are adjacent, and the sensor electrode 126 has a cut-off portion 184-1 at the boundary between subpixels 110-1 and 110-2. The cut-off portion 184-1 is located along the inner edge of the sensor electrode 126S surrounding the outer periphery of the pixel 108. The cut-off portion 184-1 is located at the boundary between sensor electrode 126S and sensor electrode 126B.

[0064] At least one cut section 184 may include multiple cut sections 184. The sensor electrode 126 may have multiple cut sections 184 in addition to the cut section 184-1 described above. The sensor electrode 126 may have cut sections 184 along the respective boundaries of multiple subpixels 110.

[0065] In the example shown in Figure 5B, pixel 108 has three subpixels 110-1, 110-2, and 110-3. Subpixel 110-1, which has a larger area than subpixels 2 and 3, is adjacent to subpixels 2 and 3, and subpixels 2 and 3 are adjacent to each other. As described above, the sensor wiring 120 has a cut-off portion 1 at the boundary between subpixel 110-1 and subpixel 2. The sensor electrode 126 further has a cut-off portion 2 at the boundary between subpixel 110-1 and subpixel 3. Cut-off portion 2, like cut-off portion 1, is located along the inner edge of the sensor electrode 126 surrounding the outer periphery of pixel 108. Cut-off portion 184-2 is located at the boundary between sensor electrode 126S and sensor electrode B. The positions of the cut portion 184-1 and the cut portion 184-2 are in the same direction when viewed from sub-pixel 110-1, in sub-pixel 110-2, and sub-pixel 110-3.

[0066] In the display device 10, the sensor electrode 126 surrounds the outer periphery of the pixel 108, extends along the boundaries of the multiple sub-pixels 110, and has at least one cut portion 184-1 at the boundary of the multiple sub-pixels 110. As a result, the overcoat layer 168 provided on the sensor electrode 126 can easily flow into the area surrounded by the sensor electrode 126. Due to this flow of the overcoat layer 168, the overcoat layer 168 can sufficiently cover the sensor electrode 126, improving the coating state of the overcoat layer 168 over the sensor electrode 126. Therefore, by applying this embodiment, a display device with improved appearance and reliability can be provided.

[0067] Furthermore, in the display device 10, the position of the cut portion 184 does not differ for each pixel 108, but is repeatedly placed in the same position, resulting in a uniform appearance of the display device 10. In addition, in a plurality of sub-pixels 110 with different areas, by providing the cut portion 184 between the sub-pixel 110 with a large area and the sub-pixel 110 with a small area, the coverage of the overcoat layer 168 on the sensor electrode 126 is improved, resulting in better visual characteristics in the vertical direction (X direction). Therefore, by applying this embodiment, a display device with improved appearance and reliability can be provided.

[0068] 2. Variations 2-1. Variation 1 The structure of the display device 10 is not limited to the structure described above. For example, as shown in Figure 6A, a cut portion 184-3 may be provided on the sensor electrode 126 surrounding the outer periphery of the pixel 108. Figure 6A is a schematic diagram showing the arrangement of sensor electrodes of a display device according to one embodiment of the present invention, and is an enlarged view of the sensor electrodes 126 provided on a plurality of sensor blocks 124, similar to Figure 4B. Figure 6B is the portion 340 enclosed by the dashed line in Figure 6A, and shows an enlarged view of the sensor electrodes 126 surrounding a plurality of pixels 108.

[0069] In addition to the cut portion 184-1 between sub-pixel 110-1 and sub-pixel 2, a cut portion 184-3 can also be provided on the sensor electrode 126S surrounding pixel 108. The cut portion 184-3 can cut the sensor electrode 126S surrounding the outer periphery of pixel 108. The cut portion 184-3 can be located between adjacent pixels 108. The cut portion 184-3 can be positioned between adjacent pixels 108, but closer to an adjacent pixel 108 that is different from the adjacent pixel 108 described above. The cut portion 184-3 can be located at the boundary of different sensor electrodes 126 shared by adjacent pixels 108. The cut portion 184-3 is located between sub-pixel 110-3 and sub-pixel 110-1 of the adjacent pixel 108. The cutting portion 184-3 can be located between the sub-pixel 110-3 of pixel 108-1 and the sub-pixel 110-1 of pixel 108-2 adjacent to pixel 108-1.

[0070] In the example shown in Figure 6, the cut portion 184-3 is provided on the sensor electrode 126 between pixel 108-1 and pixel 108-2. The cut portion 184-3 is positioned between adjacent pixels 108-2 and is located close to the adjacent pixel 108-3. The sensor electrode 126S surrounding the outer periphery of pixel 108-1 has a 126SH-1 shared with the sensor electrode 126S surrounding the outer periphery of the adjacent pixel 108-2, and a 126SH-2 shared with the sensor electrode 126S surrounding the outer periphery of the adjacent pixel 108-3. The cut portion 184-3 is located at the boundary between the shared portion 126SH-1 and the shared portion 126SH-2. The cut portion 184-3 is located between the sub-pixel 110-3 of pixel 108-1 and the sub-pixel 110-1 of the adjacent pixel 108-2.

[0071] 2-2. Variation 2 Furthermore, the structure of the display device 10 is not limited to the structure described above. For example, as shown in Figure 7, the arrangement of sub-pixels 110 can be a stripe arrangement, and as shown in Figure 8A, a plurality of cut portions 184 can be provided on the sensor electrode 126. Figure 7 is a schematic diagram showing the arrangement of pixels in a display device according to one embodiment of the present invention, and shows a plurality of pixels 108 arranged in the display area 104. Figure 8A is a schematic diagram showing the arrangement of sensor electrodes in a display device according to one embodiment of the present invention, and is the portion 300 enclosed by the dashed line in Figure 1, and is an enlarged top view of a portion of the plurality of sensor blocks 124-1, sensor block 124-3, sensor block 124-14, and sensor block 124-16. Figure 8B is a schematic diagram showing the configuration of sensor electrodes in a display device according to one embodiment of the present invention, and shows the portion 360 surrounding the plurality of pixels 108 enclosed by the dashed line in Figure 8A, and is an enlarged view of the sensor electrode 126.

[0072] As shown in Figure 7, the display device 10 can arrange a plurality of subpixels 110 in a slicing array. Subpixel 110-1 is adjacent to subpixel 110-2, and subpixel 110-2 is adjacent to subpixel 110-3. Subpixel 110-2 is positioned between subpixel 110-1 and subpixel 110-3.

[0073] The sensor electrode 126 can be formed along the boundaries of a plurality of sub-pixels 110 arranged in a sliced ​​array, surrounding the outer periphery of the pixel 108. The sensor electrode 126 can have a plurality of cutouts 184. The plurality of cutouts 184 can be located between adjacent sub-pixels 110 on the sensor electrode 126. The cutouts 184 can be located along the inner edge of the sensor electrode 126 surrounding the outer periphery of the pixel. In addition to the above positions, it is preferable that the plurality of cutouts 184 be located as close to each other as possible.

[0074] In the examples shown in Figures 8A and 8B, the cut portion 184-1 is located on the sensor electrode 126 between sub-pixels 110-1 and 110-2. The cut portion 184-4 is located between sub-pixels 110-2 and 110-3. The cut portions 184-1 and 184-4 are located closest to each other at the boundary between the sensor electrode 126S and the sensor electrode 126B. The cut portion 184-1 is located at the boundary between the sensor electrode 126S and the sensor electrode 126B between sub-pixels 110-1 and 110-2, and the cut portion 184-4 is located closer to the cut portion 184-1 at the boundary between the sensor electrode 126S and the sensor electrode 126B between sub-pixels 110-2 and 110-3.

[0075] 2-3. Variation 3 Furthermore, the structure of the display device 10 is not limited to the structure described above. For example, as shown in Figure 9, sub-pixels 110-1 to 110-3 can be arranged in a diamond array, and as shown in Figures 10A and 10B, a plurality of cut portions 184 can be provided on the sensor electrode 126. Figure 9 is a schematic diagram showing the arrangement of pixels in a display device according to one embodiment of the present invention, and shows a plurality of pixels 108 arranged in the display area 104. Figure 10A is a schematic diagram showing the arrangement of sensor electrodes in a display device according to one embodiment of the present invention, and shows an enlarged view of a portion 300 of a plurality of sensor blocks 124-1, sensor block 124-3, sensor block 124-14, and sensor block 124-16. Figure 10B is a schematic diagram showing the configuration of sensor electrodes in a display device according to one embodiment of the present invention, and shows a further enlarged view of the sensor electrode 126.

[0076] As shown in Figure 9, the display device 10 can arrange a plurality of sub-pixels 110 in a diamond arrangement. Sub-pixel 110-1 can be adjacent to sub-pixel 110-2, and sub-pixel 110-2 can be adjacent to sub-pixel 110-3. The diagonals of the diamond shape of sub-pixel 110-1 and the diagonals of the diamond shape of sub-pixel 110-3 can be aligned on a straight line 110L. A light-emitting element 110E can be provided corresponding to each sub-pixel 110, and may be arranged in a pentile arrangement.

[0077] The sensor electrode 126 can be formed along the boundary of a plurality of sub-pixels 110 arranged in a diamond array, surrounding the outer periphery of the pixel 108. The sensor electrode 126 can have a plurality of cut portions 184. The plurality of cut portions 184 can be located between adjacent sub-pixels 110 in the sensor electrode 126. The cut portions 184 can be located along the inner edge of the sensor electrode 126 surrounding the outer periphery of the pixel 108. The cut portions 184 can be located at the boundary between sensor electrode 126S and sensor electrode 126B.

[0078] The sensor electrode 126 may surround the outer periphery of a pixel 108C that is arranged across multiple sensor blocks 124, together with sensor electrodes 126 that are spaced apart from each other and arranged on other sensor blocks 124. In the example shown in Figure 10A, the pixel 108C is arranged across sensor blocks 124-1, 124-3, 124-14, and 124-16. The outer periphery of the pixel 108C is surrounded by sensor electrodes 126 arranged on each of the sensor blocks 124-1, 124-3, 124-14, and 124-16.

[0079] In the sensor electrode 126 surrounding the outer periphery of the pixel 108C, the sensor electrode 126-14 located on the sensor block 124-14 may have a portion 126-14P that extends to the sensor block 124-16. The extending portion 126-14P is separated from the sensor electrode 126-16 and continuous with the sensor electrode 126-14 located on the sensor block 124-14. When the pixel 108C is located at the boundary of the sensor block 124, the sensor electrodes 126 located on multiple sensor blocks 124 are continuous with at least one sensor electrode 126.

[0080] Next, the configuration of the sensor electrode 126 will be explained with reference to Figure 10B. Figure 10B is a schematic diagram showing the configuration of the sensor electrode of a display device according to one embodiment of the present invention. Figure 10B shows the portion 380 enclosed by the dashed line in Figure 10A, and is an enlarged view of the sensor electrode 126 surrounding the multiple pixels 108.

[0081] The sensor electrode 126 can be formed along the boundaries of a plurality of sub-pixels 110 arranged in a diamond array, surrounding the outer periphery of the pixel 108. The sensor electrode 126 can have a plurality of cut portions 184. The plurality of cut portions 184 can be located between adjacent sub-pixels 110 on the sensor electrode 126. The cut portions 184 can be located along the inner edge of the sensor electrode 126 surrounding the outer periphery of the pixel. In addition to the above positions, it is preferable to arrange the plurality of cut portions 184 at the positions furthest from each other. In a sub-pixel 110 where a plurality of cut portions 184 are arranged between adjacent sub-pixels 110, the plurality of cut portions 184 can be arranged diagonally.

[0082] In the examples shown in Figures 10A and 10B, sub-pixel 110-2 has cut-off portions 184-1 and 184-5 between it and sub-pixels 110-1 and 110-3, respectively. Cut-off portions 184-1 and 184-5 are located at the furthest points from each other at the boundary between sensor electrode 126S and sensor electrode 126B. Cut-off portions 184-1 and 184-5 are located diagonally opposite each other in sub-pixel 110-2.

[0083] 2-4. Variation 4 Alternatively, the structure of the display device 10 is not limited to the structure described above. For example, as shown in Figures 11A and 11B, four or more sub-pixels 110 can be provided in the pixel 108, and multiple cut portions 184 can be provided in the sensor electrode 126. Figure 11A is a schematic diagram showing the arrangement of sensor electrodes in a display device according to one embodiment of the present invention. Figure 11A shows the portion 400 enclosed by the dashed line in Figure 1, and is an enlarged top view of a portion of the multiple sensor blocks 124-1, sensor block 124-3, sensor block 124-14, and sensor block 124-16. Figure 11B is a schematic diagram showing the configuration of sensor electrodes in a display device according to one embodiment of the present invention, and is a further enlarged view of the sensor electrode 126.

[0084] The display device 10 has four or more sub-pixels 110 for each pixel, and sub-pixel 110-1 is adjacent to sub-pixels 110-2 and 110-4, and sub-pixel 110-3 can be adjacent to sub-pixels 110-2 and 110-4. Sub-pixels 110-1 and 110-3 are arranged diagonally, and sub-pixels 110-2 and 110-4 can be arranged diagonally. A light-emitting element 110E can be provided corresponding to each sub-pixel 110, and may be arranged in a pentile array.

[0085] The sensor electrode 126 may have a further cut portion on the outer periphery of the pixel 108N, where a portion reaches the boundary of the sensor block 124, toward the other sensor block 124. This cut portion allows the sensor electrode 126 located on sensor block 124-14 to be separated from the sensor electrode 126 located on sensor block 124-3.

[0086] In the example shown in Figure 11A, a pixel 108N located in sensor block 124-14 partially reaches the boundary with sensor block 124-3. The sensor electrode 126 positioned in sensor block 124-14 has a cut portion on the outer periphery of the pixel 108N toward sensor block 124-3.

[0087] The sensor electrode 126 may also have a cutout portion 184-6 between sub-pixels 110-3 and 110-4. As shown in Figure 11B, the cutout portion 184-6 can be located along the inner edge of the sensor electrode 126 surrounding the outer periphery of the pixel. The cutout portion 184-6 can be located at the boundary between sensor electrode 126S and sensor electrode 126B.
