[0027] Hereinafter, embodiments will be described with reference to the accompanying drawings.

[0028] Furthermore, the disclosed contents are merely examples, and appropriate modifications that are readily apparent to those skilled in the art while maintaining the spirit of the invention are naturally also within the scope of the present invention. Furthermore, to clarify the description, the drawings are sometimes schematically illustrated compared to the embodiments, but this is merely an example and does not limit the interpretation of the present invention. Furthermore, in this specification and the drawings, components that perform the same or similar functions as those described above are denoted by the same reference numerals, and repeated detailed descriptions are sometimes omitted.

[0029] In each embodiment, as an example of a display device, a display device with a touch detection function is described. Touch detection methods include optical, resistive, electrostatic capacitance, electromagnetic induction, and other methods. Among the various detection methods mentioned above, the electrostatic capacitance method is a detection method that uses the change in electrostatic capacitance caused by the proximity or contact of an object (such as a finger, etc.). It has the advantages of being able to be implemented with a relatively simple structure and consuming less power. In each embodiment, a display device with a touch detection function that uses the electrostatic capacitance method is mainly described.

[0030] Furthermore, electrostatic capacitance methods include: mutual capacitance methods, which generate an electric field between a pair of transmitting electrodes (driving electrodes) and receiving electrodes (detection electrodes) that are separated from each other, and detect changes in the electric field caused by the approach or contact of an object; and self-capacitance methods, which use a single electrode to detect changes in electrostatic capacitance caused by the approach or contact of an object. In each embodiment, the display device with a touch detection function that uses the self-capacitance method is mainly described.

[0031] (First embodiment)

[0032] Figure 1This is a top view showing a structural example of the display device DSP1 involved in the first embodiment. In one example, the first direction X, the second direction Y, and the third direction Z are orthogonal to each other, but they can also intersect at angles other than 90 degrees. The first direction X and the second direction Y are equivalent to directions parallel to the main surface of the substrate constituting the display device DSP1, and the third direction Z is equivalent to the thickness direction of the display device DSP1. In this specification, the third direction Z is defined as up, and the direction on the opposite side of the third direction Z is defined as down. When set as "the second component above the first component" and "the second component below the first component", the second component can be in contact with the first component or can be located at a position separated from the first component. In addition, in this specification, there is an observation position for observing the display device DSP1 on the front end side of the arrow showing the third direction Z, and observation from this observation position toward the X-Y plane defined by the first direction X and the second direction Y is referred to as "looking down".

[0033] like Figure 1 As shown, the display device DSP1 includes a display panel PNL, a flexible printed circuit board (FPC), and a circuit board (PCB). The display panel PNL and the circuit board (PCB) are electrically connected via the flexible printed circuit board (FPC). More specifically, the terminal portion T of the display panel PNL and the connection portion CN of the circuit board (PCB) are electrically connected via the flexible printed circuit board (FPC).

[0034] The display panel PNL includes a display area DA for displaying an image and a frame-shaped peripheral area SA surrounding the display area DA. The display area DA is sometimes referred to as a display portion. The peripheral area SA is sometimes referred to as a peripheral portion, a frame portion, or a non-display portion. Pixels PX are arranged in the display area DA. Specifically, in the display area DA, a plurality of pixels PX are arranged in a matrix along a first direction X and a second direction Y.

[0035] In this embodiment, a pixel PX includes red (R), green (G), and blue (B) sub-pixels SP. Furthermore, each sub-pixel SP includes multiple segment pixels SG. Each segment pixel SG has a pixel electrode with a different area. By switching the display and non-display of these multiple segment pixels SG, grayscale is generated for each sub-pixel SP.

[0036] As in Figure 1 As shown in the enlarged view in the figure, the segment pixel SG includes a switching element SW, a pixel circuit PC, a pixel electrode PE, a common electrode CE, a liquid crystal layer LC, and the like.

[0037] The switching element SW is formed of, for example, a thin film transistor (TFT), and is electrically connected to the scan line G and the signal line S. The scan line G is electrically connected to the switching element SW in each of the segment pixels SG arranged in the first direction X. The signal line S is electrically connected to the switching element SW in each of the segment pixels SG arranged in the second direction Y.

[0038] The pixel electrode PE is electrically connected to the switching element SW via the pixel circuit PC. The pixel electrodes PE each face the common electrode CE, and the liquid crystal layer LC is driven by the electric field generated between the pixel electrode PE and the common electrode CE. While this embodiment shows a structure in which the pixel electrode PE is electrically connected to the switching element SW via the pixel circuit PC, the pixel electrode PE may also be electrically connected to the switching element SW without intervening through the pixel circuit PC.

[0039] Figure 1 Among the multiple concentric circles shown, the area of the innermost circle corresponds to the display area DA, and the area obtained by excluding the area of the innermost circle from the area of the outermost circle corresponds to the peripheral area SA. Figure 1 The hatched area corresponds to the display area DA, and the remaining area corresponds to the peripheral area SA.

[0040] Furthermore, in this embodiment, the display area DA is circular and the surrounding area SA surrounding the display area DA is also of the same type of shape. However, the present invention is not limited thereto. The display area DA may not be circular, and the surrounding area SA may have a different shape from the display area DA. For example, the display area DA and the surrounding area SA may be polygonal. Furthermore, if the display area DA is polygonal, the surrounding area SA may also be circular, which is a different shape from the display area DA.

[0041] In the display area DA, the common electrode CE is arranged on the entire surface. Figure 1 As shown, the common electrode CE has a first lead-out wiring CEL extending to the vicinity of the periphery of the detection electrodes Rx3 and Rx7, which will be described later. The first lead-out wiring CEL extends from the display area DA toward the peripheral area SA and is electrically connected to a wiring (not shown) for supplying power to the common electrode CE via a conductive bead (conductive component) included in the sealing material, which will be described later. In addition, the detection electrode Rx3, which is divided into two by the first lead-out wiring CEL, is electrically connected via the Rx terminal portion RT, which will be described later. Similarly, the detection electrode Rx7, which is divided into two by the first lead-out wiring CEL, is electrically connected via the Rx terminal portion RT, which will be described later.

[0042] like Figure 1 As shown in FIG. 1 , in the peripheral area SA, a plurality of detection electrodes Rx1 to Rx8 are arranged so as to surround the display area DA. Figure 1 , eight detection electrodes Rx1 to Rx8 are shown, but the number of detection electrodes Rx arranged in the peripheral area SA is not limited thereto, and any number of detection electrodes Rx may be arranged to surround the display area DA.

[0043] The plurality of detection electrodes Rx1 to Rx8 are electrically connected to a terminal portion T located in the peripheral area SA via Rx wiring (not shown). The Rx wiring extends, for example, along the periphery of the detection electrodes Rx1 to Rx8. The Rx wiring is used to supply drive signals Tx to the detection electrodes Rx1 to Rx8 and output detection signals RxAFE from the detection electrodes Rx1 to Rx8.

[0044] In addition, if Figure 1 As shown, in the peripheral area SA, the first shield electrode SE1 and the second shield electrode SE2 are arranged to surround the display area DA. More specifically, when viewed from above, the annular (doughnut-shaped) first shield electrode SE1 is arranged to surround the display area DA. Furthermore, when viewed from above, the second shield electrode SE2 is arranged to surround the common electrode CE. When viewed from above, the first shield electrode SE1 and the second shield electrode SE2 at least partially overlap, with the first shield electrode SE1 being arranged below the second shield electrode SE2.

[0045] like Figure 1 As shown, the second shield electrode SE2 includes a second lead-out wiring SEL. This second lead-out wiring SEL extends to near the periphery of the detection electrodes Rx2 and Rx6 and is electrically connected to a wiring (not shown) for supplying power to the second shield electrode SE2 via a conductive bead (conductive member) included in the sealing material (described later). Furthermore, the detection electrode Rx2, which is bisected by the second lead-out wiring SEL, is electrically connected via an Rx terminal portion RT (described later). Similarly, the detection electrode Rx6, which is bisected by the second lead-out wiring SEL, is electrically connected via an Rx terminal portion RT (described later).

[0046] A GND voltage (the same potential as that of the detection electrode Rx) or a predetermined DC voltage (fixed voltage) is applied to the first shield electrode SE1 and the second shield electrode SE2 via the various wirings described above.

[0047] like Figure 1 As shown, a touch controller TC, a display controller DC, a CPU 1 and the like are provided on the circuit substrate PCB.

[0048] The touch controller TC outputs drive signals Tx to the plurality of detection electrodes Rx1 to Rx8 arranged on the display panel PNL and receives detection signals (RxAFE signals) from the detection electrodes Rx1 to Rx8 (that is, detects the approach or contact of an external proximate object). The touch controller TC can also be called a detection unit.

[0049] The display controller DC outputs an image signal for representing an image displayed in the display area DA of the display panel PNL.

[0050] The CPU 1 performs operations such as outputting a synchronization signal that defines the operation timing of the touch controller TC and the display controller DC, and executing an operation corresponding to a touch detected by the touch controller TC.

[0051] In addition, Figure 1 In FIG. 1 , the touch controller TC, the display controller DC, and the CPU 1 are shown as being implemented by one semiconductor chip, but these implementations are not limited thereto. For example, Figure 2 As shown, only the touch controller TC is separated as a separate body, and then each part is mounted on the circuit substrate PCB. Figure 3 As shown, the touch controller TC and CPU1 are separately installed on the circuit substrate PCB, and the display controller DC is installed on the display panel PNL through the COG (Chip On Glass) method. Figure 4 As shown, only the CPU 1 is mounted on the circuit substrate PCB, and the touch controller TC and the display controller DC are mounted on the display panel PNL through a COG method.

[0052] Figure 5 It means using Figure 1 The cross-sectional view of the display device DSP1 taken along line AB is shown. Next, the structure on the display area DA side and the structure on the peripheral area SA side will be described separately.

[0053] The display device DSP1 includes a first substrate SUB1, a second substrate SUB2, a sealant 30, a liquid crystal layer LC, a polarizer PL, and a cover member CM. The first substrate SUB1 can be referred to as an array substrate, and the second substrate SUB2 can be referred to as a counter substrate. The first and second substrates SUB1 and SUB2 are flat plates parallel to the XY plane.

[0054] The first substrate SUB1 and the second substrate SUB2 overlap in a plan view and are bonded (connected) by a sealant 30. The liquid crystal layer LC is held between the first substrate SUB1 and the second substrate SUB2 and sealed by the sealant 30. The sealant 30 includes a plurality of metal-coated conductive beads 31, thereby electrically connecting the structure on the first substrate SUB1 side to the structure on the second substrate SUB2 side.

[0055] A polarizing plate PL is provided on the second substrate SUB2 , and a cover member CM is further provided on the polarizing plate PL.

[0056] In addition, Figure 5, the display device DSP1 is shown as a reflective display device without a backlight unit, but the present invention is not limited thereto. The display device DSP1 may also be a display device using organic EL as pixels or a transmissive display device equipped with a backlight unit. Alternatively, the display device DSP1 may be a display device that combines reflective and transmissive types. As the backlight unit, various types of backlight units may be used. For example, as the light source, a light source using a light emitting diode (LED) or a light source using a cold cathode fluorescent lamp (CCFL) may be used. In addition, when a backlight unit is provided, a polarizing plate is provided between the first substrate SUB1 and the backlight unit (i.e., below the first substrate SUB1).

[0057] like Figure 5 As shown, on the display area DA side, the first substrate SUB1 includes a transparent substrate 10, a switching element SW, a pixel circuit PC, a planarization film 11, a pixel electrode PE and an alignment film AL1. In addition to the above structure, the first substrate SUB1 also includes Figure 1 The scanning lines G, signal lines S, etc. shown in FIG. Figure 5 These illustrations are omitted.

[0058] The transparent substrate 10 includes a principal surface (lower surface) 10A and a principal surface (upper surface) 10B opposite principal surface 10A. The switching element SW and the pixel circuit PC are arranged on principal surface 10B. The planarization film 11 is composed of at least one insulating film and covers the switching element SW and the pixel circuit PC.

[0059] The pixel electrode PE is disposed on the planarization film 11 and is connected to the pixel circuit PC through a contact hole formed in the planarization film 11. The switching element SW, the pixel circuit PC, and the pixel electrode PE are disposed for each segment pixel SG. The alignment film AL1 covers the pixel electrode PE and contacts the liquid crystal layer LC.

[0060] In addition, Figure 5 In FIG, the switching element SW and the pixel circuit PC are simplified, but in fact the switching element SW and the pixel circuit PC include semiconductor layers and electrodes of each layer. Figure 5 Although not shown in the figure, the switching element SW is electrically connected to the pixel circuit PC. Figure 5 The scanning lines G and the signal lines S, which are not shown in the figure, are arranged, for example, between the transparent substrate 10 and the planarization film 11 .

[0061] like Figure 5 As shown, on the display area DA side, the second substrate SUB2 includes a transparent substrate 20, a light shielding film BM, a color filter CF, an overcoat layer OC, a common electrode CE, and an alignment film AL2.

[0062] The transparent substrate 20 includes a principal surface (lower surface) 20A and a principal surface (upper surface) 20B opposite the principal surface 20A. The principal surface 20A of the transparent substrate 20 faces the principal surface 10B of the transparent substrate 10. A light-shielding film BM demarcates each segmented pixel SG. A color filter CF is disposed on the principal surface 20A side of the transparent substrate 20, facing the pixel electrode PE, with a portion overlapping the light-shielding film BM. The color filter CF includes a red filter, a green filter, and a blue filter. An overcoat layer OC covers the color filter CF.

[0063] The common electrode CE is disposed across the plurality of segment pixels SG (the plurality of pixels PX) and faces the plurality of pixel electrodes PE in the third direction Z. The common electrode CE is disposed on the overcoat layer OC. The alignment film AL2 covers the common electrode CE and contacts the liquid crystal layer LC.

[0064] The liquid crystal layer LC is arranged between the main surface 10B and the main surface 20A.

[0065] Transparent substrates 10 and 20 are insulating substrates such as glass substrates or plastic substrates. Planarization film 11 is formed of a transparent insulating material such as silicon oxide, silicon nitride, silicon oxynitride, or acrylic resin. In one example, planarization film 11 includes an inorganic insulating film and an organic insulating film.

[0066] The pixel electrode PE is formed as a reflective electrode, for example, a three-layer stack of indium zinc oxide (IZO), silver (Ag), and indium zinc oxide (IZO). Alternatively, the pixel electrode PE may be formed as a reflective electrode, for example, by placing a metal such as silver (Ag) on top of the pixel electrode PE, which is formed as a transparent electrode. The common electrode CE is formed of a transparent conductive material such as indium tin oxide (ITO) or indium zinc oxide (IZO).

[0067] The alignment films AL1 and AL2 are horizontal alignment films having an alignment regulating force substantially parallel to the XY plane. The alignment regulating force can be imparted by rubbing treatment or photo-alignment treatment.

[0068] like Figure 5 As shown, on the peripheral area SA side, the first substrate SUB1 includes a transparent substrate 10, a wiring group LG including a plurality of wirings L, a planarization film 11, a first shield electrode SE1, an Rx terminal portion RT, an interlayer insulating film 12, and an alignment film AL1. Detailed descriptions of the structures already described on the display area DA side will be omitted.

[0069] On the main surface 10B side of the transparent substrate 10, a wiring group LG including a plurality of wirings L is arranged. The plurality of wirings L included in the wiring group LG are covered with a planarization film 11. Figure 5In the figure, as the plurality of wires L included in the wire group LG, six wires L including the first shield wire SL1 and the Rx wire RL described later are shown. However, the number of the plurality of wires L included in the wire group LG is not limited to this. The plurality of wires L included in the wire group LG may further include a signal line S, a wire for supplying power to the second shield electrode SE2, a wire for supplying power to the common electrode CE, and the like.

[0070] The first shield electrode SE1 is provided on the planarizing film 11, facing (part of) the plurality of wires L included in the wire group LG, and is positioned between the wire group LG and the detection electrode Rx in the third direction Z. Therefore, the first shield electrode SE1 is arranged on the same layer as the pixel electrode PE on the display area DA side and is formed, for example, of the same transparent conductive material as the pixel electrode PE.

[0071] The first shield electrode SE1 is connected to the first shield wiring SL1, one of the wirings included in the wiring group LG, via a contact hole formed in the planarization film 11. The contact hole is formed at a position overlapping the sealant 30 when viewed from above. In other words, the first shield electrode SE1 extends from a region in the peripheral area SA where the sealant 30 is not disposed (a region in the peripheral area SA where the liquid crystal layer LC is disposed) to a portion of the region where the sealant 30 is disposed, and is connected to the first shield wiring SL1 via the contact hole.

[0072] A GND voltage (the same potential as the detection electrode Rx) or a predetermined DC voltage (fixed voltage) is applied to the first shield electrode SE1 via the first shield wiring SL1. This prevents capacitive coupling between the detection electrode Rx and other structures (e.g., the multiple wirings L included in the wiring group LG).

[0073] The Rx terminal portion RT is provided on the planarizing film 11. When viewed from above, the Rx terminal portion RT is located at a position overlapping the sealing material 30 and is connected to the Rx wiring RL, one of the wirings included in the wiring group LG, via a contact hole formed in the planarizing film 11. The Rx terminal portion RT is electrically connected to the detection electrode Rx provided on the second substrate SUB2 side via a conductive bead 31 included in the sealing material 30.

[0074] The interlayer insulating film 12 is provided to cover the first shield electrode SE1. The alignment film AL1 covers the planarization film 11 and the interlayer insulating film 12 in the region where the liquid crystal layer LC is disposed in the peripheral region SA, and is in contact with the liquid crystal layer LC.

[0075] like Figure 5As shown, the second substrate SUB2 includes a transparent substrate 20, a light shielding film BM, an overcoat layer OC, a second shielding electrode SE2, a detection electrode Rx, and an alignment film AL2 on the peripheral area SA side. Detailed description of the structure already described on the display area DA side will be omitted.

[0076] A light-shielding film BM is disposed on the principal surface 20A side of the transparent substrate 20. The light-shielding film BM is disposed over substantially the entire surface of the peripheral area SA. The overcoat layer OC covers the light-shielding film BM together with the color filter CF on the display area DA side.

[0077] The second shielding electrode SE2 is disposed on the overcoat layer OC. The second shielding electrode SE2 is disposed closer to the display area DA than the detection electrode Rx in a plan view (between the detection electrode Rx and the display area DA). The second shielding electrode SE2 is disposed on the same layer as the common electrode CE on the display area DA side, and is formed of, for example, the same transparent conductive material as the common electrode CE. Figure 5 The cross section shown in the figure extends to the region where the sealing material 30 is arranged, and is electrically connected to the shield terminal portion (not shown) and the second shield wiring (not shown) arranged on the first substrate SUB1 side through the conductive beads 31 included in the sealing material 30.

[0078] A GND voltage (the same potential as the detection electrode Rx) or a predetermined DC voltage (fixed voltage) is applied to the second shield electrode SE2 via the aforementioned second shield wiring, shield terminal portion, and conductive bead 31. Thus, the second shield electrode SE2 can suppress capacitive coupling between the detection electrode Rx and other structures (e.g., the pixel electrode PE and the common electrode CE on the display area DA side).

[0079] like Figure 5 As shown, the detection electrode Rx, like the second shield electrode SE2, is arranged in the same layer as the common electrode CE on the display area DA side and is formed, for example, from the same transparent conductive material as the common electrode CE. The detection electrode Rx extends from an area in the peripheral area SA where the sealant 30 is not arranged (the area in the peripheral area SA where the liquid crystal layer LC is arranged) to an area where the sealant 30 is arranged. The detection electrode Rx is electrically connected to the Rx terminal portion RT and Rx wiring RL arranged on the first substrate SUB1 side via conductive beads 31 included in the sealant 30.

[0080] In the peripheral area SA, the alignment film AL2 covers the overcoat layer OC, the second shield electrode SE2, and the detection electrode Rx in the region where the liquid crystal layer LC is arranged, and is in contact with the liquid crystal layer LC.

[0081] In addition, Figure 5, there is shown a structure when the liquid crystal mode, which is classified into two types according to the direction of application of the electric field for changing the orientation of the liquid crystal molecules contained in the liquid crystal layer LC, is a so-called longitudinal electric field mode. This structure can also be applied to the case where the liquid crystal mode is a so-called transverse electric field mode. The above-mentioned longitudinal electric field mode includes, for example, a TN (Twisted Nematic) mode, a VA (Vertical Alignment) mode, and the like. In addition, the above-mentioned transverse electric field mode includes, for example, an IPS (In-Plane Switching) mode, an FFS (Fringe Field Switching) mode which is one of the IPS modes, and the like. When the transverse electric field mode is adopted, the common electrode CE provided in the display area DA is provided on the side of the first substrate SUB1, opposite to the pixel electrode PE via a thin insulating layer.

[0082] Figure 6 1 is an exploded perspective view showing a portion of the display device DSP1 according to the present embodiment located in the peripheral area SA. Figure 7 1 is a plan view showing a portion of the structure of the display device DSP1 according to the present embodiment, which is located in the peripheral area SA. Figure 6 and Figure 7 In the figure, in order to facilitate understanding of the upper and lower relationships and sizes of each structure, some structures are shown with sizes different from the actual ones.

[0083] like Figure 6 and Figure 7 As shown, the first shielding electrode SE1 extends from an area where the sealing material 30 is not provided to a portion of an area where the sealing material 30 is provided. Figure 5 Although described above and not shown in the drawings here, the first shield electrode SE1 is connected to the first shield wiring SL1 via a contact hole formed at a position overlapping with the sealing material 30 in a plan view.

[0084] The Rx terminal portion RT is provided in the same layer as the first shield electrode SE1. Unlike the first shield electrode SE1, the entire surface of the Rx terminal portion RT overlaps with the sealing material 30 in a plan view. A predetermined gap is provided between the first shield electrode SE1 and the Rx terminal portion RT.

[0085] like Figure 6 and Figure 7 As shown, the first shield electrode SE1 overlaps with the interlayer insulating film 12 in a plan view and is covered by the interlayer insulating film 12. This prevents the first shield electrode SE1 from being electrically connected to the detection electrode Rx on the second substrate SUB2 side via the conductive beads 31 included in the sealing material 30.

[0086] like Figure 6 and Figure 7 As shown, the detection electrode Rx extends from an area of the peripheral area SA where the sealant 30 is not located to an area where the sealant 30 is located. In a first area A1, where the detection electrode Rx overlaps with the sealant 30, the interlayer insulating film 12, and the first shield electrode SE1 when viewed from above, the detection electrode Rx has a shape that differs from that of the second area A2, which is the remaining area. More specifically, in the first area A1, where the detection electrode Rx overlaps with the sealant 30, the interlayer insulating film 12, and the first shield electrode SE1 when viewed from above, the detection electrode Rx has a shape composed of multiple thin lines. In the second area A2, the detection electrode Rx is formed into a flat plate parallel to the XY plane.

[0087] like Figure 6 and Figure 7 As shown, in the first area A1, the detection electrode Rx has a plurality of intersecting thin line portions forming a mesh. The openings of the mesh formed by the plurality of thin line portions are preferably larger than the diameter of the conductive beads 31 included in the sealing material 30. The width of the thin line portions is preferably smaller than the diameter of the conductive beads 31 included in the sealing material 30.

[0088] like Figure 7 As shown in FIG. 1 , in the peripheral area SA, a wiring group LG including a plurality of wirings L is provided below the first shield electrode SE1 and the Rx terminal portion RT. Figure 7 In order to prevent the figure from becoming complicated, only a part of the wirings L included in the wiring group LG is shown in detail, and the other wirings L are simplified in the illustration.

[0089] Here, the effects of the display device DSP1 according to this embodiment are described using comparative examples. The comparative examples are used to illustrate a portion of the effects of the display device DSP1 according to this embodiment, and the effects common to the comparative examples and this embodiment are not excluded from the scope of the present invention.

[0090] Figure 8 is an exploded perspective view showing a portion of the structure of the display device DSP1′ according to the comparative example, located in the peripheral area SA. Figure 9 1 is a plan view showing a partial structure of the display device DSP1 ′ according to the comparative example, located in the peripheral area SA.

[0091] like Figure 8 and Figure 9 As shown, the display device DSP1 ′ of the comparative example differs from the display device DSP1 of the present embodiment in that the detection electrode Rx is formed in a flat plate shape parallel to the XY plane in the first area A1 as in the second area A2 .

[0092] In the display device DSP1′ of the comparative example, the detection electrode Rx is also formed in the first area A1 as a flat plate parallel to the X-Y plane. Therefore, if a crack occurs in the interlayer insulating film 12 during the manufacturing process of the display device DSP1′, the first shielding electrode SE1 exposed due to the crack is electrically connected to the detection electrode Rx on the second substrate SUB2 side via the conductive beads 31 included in the sealing material 30, and there is a risk of short circuit.

[0093] In contrast, in the display device DSP1 involved in this embodiment, the detection electrode Rx is formed as a plurality of mesh-like fine line portions in the first area A1. Therefore, even if cracks occur in the interlayer insulating film 12 during the manufacturing process of the display device DSP1, the risk of the first shielding electrode SE1 exposed due to the cracks being electrically connected to the detection electrode Rx on the second substrate SUB2 side via the conductive beads 31 included in the sealing material 30 can be reduced.

[0094] In more detail, since the detection electrode Rx is constructed as a plurality of mesh-like thin line portions in the first area A1, compared with the structure involved in the comparative example, the electrode area of the detection electrode Rx overlapped by the first shielding electrode SE1 exposed due to the above-mentioned cracks when viewed from above can be reduced, and the risk of short circuit between the detection electrode Rx and the first shielding electrode SE1 due to electrical connection via the conductive beads 31 can be reduced.

[0095] In addition, by configuring the detection electrode Rx in the first area A1 as a mesh of multiple thin lines, the overall electrode area of the detection electrode Rx can be reduced. Therefore, the capacitance added when an external proximity object such as a finger contacts the touch becomes smaller, and the time constant can be correspondingly reduced. By reducing the time constant, the number of pulses used for touch detection can be increased to reduce noise, the touch detection period used for touch detection can be reduced to increase the display period for displaying an image, and the time spent on signal processing can be shortened. Furthermore, by reducing the capacitance added when an external proximity object such as a finger contacts the touch controller TC, the capacitance can be brought within the upper limit of the detection range of the touch controller TC, or a margin can be provided for the upper limit of the detection range.

[0096] Here, as a modification of the present embodiment, another shape of the detection electrode Rx that can reduce the risk of electrical connection between the detection electrode Rx and the first shield electrode SE1 via the conductive beads 31 in the first area A1 will be described.

[0097] (Modification of the first embodiment)

[0098] Figure 10 1 is a top view showing the shape of the detection electrode Rx involved in the modification. Figure 10 In the figure, the interlayer insulating film 12 and the sealing material 30 are omitted. Figure 10As shown, in the first area A1, the detection electrode Rx may also have multiple zigzag-shaped thin lines. The multiple zigzag-shaped thin lines are arranged at predetermined intervals and are formed so as not to intersect with each other. Preferably, the predetermined interval, i.e., the interval between one zigzag-shaped thin line and other adjacent zigzag-shaped thin lines, is larger than the diameter of the conductive beads 31 included in the sealing material 30.

[0099] exist Figure 10 In the shape shown, the electrode area of the detection electrode Rx overlapped by the first shielding electrode SE1 exposed in the first area A1 due to the above-mentioned crack when viewed from above can be made smaller than the structure involved in the above-mentioned comparative example (in the first area A1, the detection electrode Rx is formed into a flat plate-shaped structure), so that the same effect as the above-mentioned effect can be obtained.

[0100] Furthermore, in the first area A1, the detection electrode Rx may have multiple linear or wavy thin line portions instead of the aforementioned zigzag thin line portions. In either case, the electrode area of the detection electrode Rx in the first area A1 can be made smaller than in the structure of the comparative example described above, and thus the same effect as described above can be achieved.

[0101] In the embodiment described above, in the first area A1 where there is a risk of electrical connection between the detection electrode Rx and the first shield electrode SE1 via the conductive beads 31, the detection electrode Rx has a shape consisting of multiple thin lines, thereby reducing this risk. However, from the perspective of reducing this risk, the first shield electrode SE1, rather than the detection electrode Rx, may have a shape consisting of multiple thin lines in the first area A1. That is, the first shield electrode SE1 may have multiple thin lines in the first area A1 in a mesh pattern, a zigzag pattern, a straight pattern, or a wavy pattern.

[0102] Even in this case, the electrode area of the first shield electrode SE1 overlapping with the detection electrode Rx in a plan view in the first area A1 can be reduced, so the above-mentioned risk can be reduced, and the same effect as the above-mentioned effect can be obtained.

[0103] In addition, in the first area A1, when the first shielding electrode SE1 has a shape composed of multiple thin line portions, the capacitive coupling between the detection electrode Rx and the wiring L included in the wiring group LG cannot be shielded in the gaps between the multiple thin line portions. Therefore, it is preferred that the wiring L included in the wiring group LG is not provided under the first shielding electrode SE1 in the first area A1.

[0104] In addition, from the perspective of reducing the above-mentioned risk, both the detection electrode Rx and the first shielding electrode SE1 may have a shape consisting of a plurality of thin line portions in the first area A1. Figure 11 As shown in FIG. 1 , it is preferable that the plurality of thin line portions of the detection electrode Rx and the plurality of thin line portions of the first shield electrode SE1 are formed so as not to overlap when viewed from above. Figure 11 In, also with Figure 10 Likewise, illustration of the interlayer insulating film 12 and the sealing material 30 is omitted.

[0105] Therefore, it is preferred that the multiple thin line portions of the detection electrode Rx and the multiple thin line portions of the first shielding electrode SE1 are not formed into a mesh shape, but are formed into a zigzag line shape, a straight line shape, or a wavy line shape. Thus, in the first area A1, the detection electrode Rx and the first shielding electrode SE1 do not overlap when viewed from above, so even if the first shielding electrode SE1 is exposed due to the above-mentioned cracks, the detection electrode Rx and the first shielding electrode SE1 will not be electrically connected via the conductive beads 31, and the above-mentioned risks can be eliminated. The fact that the detection electrode Rx and the first shielding electrode SE1 do not overlap when viewed from above includes the following situations: the detection electrode Rx and the first shielding electrode SE1 are alternately arranged when viewed from above; the thin line portion of one electrode is arranged between the thin line portions of the other electrode when viewed from above. In addition, as Figure 11 As shown, the tip of the thin line portion of the first shield electrode SE1 may not be connected to any place (any component). In addition, the tip of the thin line portion of the first shield electrode SE1 may not overlap with the detection electrode Rx located in the second area A2 in a plan view.

[0106] Furthermore, in the first area A1, when both the detection electrode Rx and the first shielding electrode SE1 have a shape consisting of a plurality of thin line portions, the gaps between the plurality of thin line portions of the first shielding electrode SE1 cannot shield the detection electrode Rx from capacitive coupling with the wiring L included in the wiring group LG. Figure 11 As shown, it is preferable that the wirings L included in the wiring group LG are not provided under the first shield electrode SE1 in the first area A1.

[0107] The display device DSP1 according to the first embodiment described above has a structure in which, in a first region A1 where the detection electrode Rx, the sealant 30, the interlayer insulating film 12, and the first shield electrode SE1 overlap in a plan view, at least one of the detection electrode Rx and the first shield electrode SE1 has a shape consisting of multiple thin line portions. This structure reduces the risk of a short circuit between the detection electrode Rx and the first shield electrode SE1 due to electrical connection via the conductive beads 31 included in the sealant 30, even if cracks develop in the interlayer insulating film 12 covering the first shield electrode SE1 during the manufacturing process of the display device DSP1, exposing a portion of the first shield electrode SE1.

[0108] (Second embodiment)

[0109] Next, a second embodiment will be described. Figure 12 is a plan view showing a configuration example of a display device DSP2 according to the second embodiment. Figure 13 It means using Figure 12 The cross-sectional view of the display device DSP2 taken along line CD is shown.

[0110] like Figure 13 As shown, the display device DSP2 according to the second embodiment differs from the structure of the first embodiment described above in that the detection electrodes Rx are arranged on the first substrate SUB1 side. Figure 12 and Figure 13 As shown, the display device DSP2 according to the second embodiment differs from the structure of the first embodiment described above in that the first shield electrode SE1 is not provided on the first substrate SUB1 side. The following mainly describes the structure unique to the display device DSP2 according to the second embodiment, and omits descriptions of the structures common to the first embodiment.

[0111] like Figure 12 As shown, the first lead wiring CEL led out from the common electrode CE extends to the periphery of the detection electrodes Rx3 and Rx7 and is electrically connected to wiring (not shown) for supplying power to the common electrode CE via the conductive beads 31 included in the sealing material 30 .

[0112] In addition, if Figure 12 As shown, in a plan view, the second lead wiring SEL extended from the second shielding electrode SE2 arranged to surround the common electrode CE extends to the periphery of the detection electrodes Rx2 and Rx6, and is electrically connected to the wiring for supplying power to the second shielding electrode SE2 described later via the conductive beads 31 included in the sealing material 30.

[0113] like Figure 13 As shown, the detection electrode Rx is provided on the planarization film 11 and is connected to the Rx wiring RL, one of the wirings included in the wiring group LG, via a contact hole formed in the planarization film 11. The contact hole is formed at a position overlapping the sealant 30 when viewed from above. In other words, the detection electrode Rx extends from an area in the peripheral area SA where the sealant 30 is not provided (an area in the peripheral area SA where the liquid crystal layer LC is provided) to a portion of the area where the sealant 30 is provided, and is connected to the Rx wiring RL via the contact hole.

[0114] In addition, if Figure 13 As shown, an interlayer insulating film 12 is provided on the detection electrode Rx so as to cover the detection electrode Rx.

[0115] like Figure 13 As shown, the second shielding electrode SE2 extends from an area where the sealing material 30 is not configured (an area where the liquid crystal layer LC is configured in the peripheral area SA) to an area where the sealing material 30 is configured, and is electrically connected to the shielding terminal portion ST and the second shielding wiring SL2 configured on the side of the first substrate SUB1 through the conductive beads 31 contained in the sealing material 30.

[0116] A GND voltage (the same potential as the detection electrode Rx) or a predetermined DC voltage (fixed voltage) is applied to the second shield electrode SE2 via the second shield wiring SL2, the shield terminal ST, and the conductive bead 31. Thus, the second shield electrode SE2 can suppress capacitive coupling between the detection electrode Rx and other structures (e.g., the pixel electrode PE and the common electrode CE on the display area DA side).

[0117] Figure 14 1 is an exploded perspective view showing a portion of the display device DSP2 according to the present embodiment located in the peripheral area SA. Figure 15 1 is a plan view showing a portion of the structure of the display device DSP2 according to the present embodiment, which is located in the peripheral area SA. Figure 14 and Figure 15 In the figure, in order to facilitate understanding of the upper and lower relationships and sizes of each structure, some structures are shown with sizes different from the actual ones.

[0118] like Figure 14 and Figure 15 As shown, the detection electrode Rx extends from the area where the sealing material 30 is not provided to a portion of the area where the sealing material 30 is provided in the peripheral area SA. Figure 13 Although described above and not shown here, the detection electrode Rx is connected to the Rx line RL via a contact hole formed at a position overlapping with the sealing material 30 in a plan view.

[0119] A shield terminal portion ST is provided in the same layer as the detection electrode Rx. Unlike the detection electrode Rx, the entire surface of the shield terminal portion ST overlaps with the sealing material 30 in a plan view. A predetermined gap is provided between the detection electrode Rx and the shield terminal portion ST.

[0120] like Figure 14 and Figure 15 As shown, the detection electrode Rx overlaps with the interlayer insulating film 12 in a plan view and is covered by the interlayer insulating film 12. This prevents the detection electrode Rx from being electrically connected to the second shield electrode SE2 on the second substrate SUB2 side via the conductive beads 31 included in the sealing material 30.

[0121] like Figure 14 and Figure 15 As shown, the second shielding electrode SE2 extends from an area in the peripheral area SA where the sealing material 30 is not provided to an area in which the sealing material 30 is provided. The detection electrode Rx has a shape different from that of the second area A2 which is the other area in the first area A1 where the detection electrode Rx overlaps with the interlayer insulating film 12, the sealing material 30 and the second shielding electrode SE2 when viewed from above. More specifically, the detection electrode Rx has a shape consisting of a plurality of thin line portions in the first area A1 where the detection electrode Rx overlaps with the interlayer insulating film 12, the sealing material 30 and the second shielding electrode SE2 when viewed from above, and is formed into a flat plate parallel to the XY plane in the other second area A2. In addition, as shown in FIG. Figure 15 As shown, the tip of the thin line portion of the detection electrode Rx may not be connected to any place (any component). In addition, the tip of the thin line portion of the detection electrode Rx may not overlap with the second shielding electrode SE2 located in the second area A2 in a plan view.

[0122] like Figure 14 and Figure 15 As shown, in the first area A1, the detection electrode Rx has a plurality of intersecting thin line portions forming a mesh. The openings of the mesh formed by the plurality of thin line portions are preferably larger than the diameter of the conductive beads 31 included in the sealing material 30. The width of the thin line portions is preferably smaller than the diameter of the conductive beads 31 included in the sealing material 30.

[0123] like Figure 15 As shown in FIG. 1 , in the surrounding area SA, a wiring group LG including a plurality of wirings L is provided below the detection electrodes Rx and the shield terminal portion ST.

[0124] like Figure 14 and Figure 15 As shown, in the first area A1, the detection electrode Rx has a plurality of mesh-like fine line portions. Therefore, even if cracks are generated in the interlayer insulating film 12 during the manufacturing process of the display device DSP2, the risk of the detection electrode Rx exposed due to the cracks being electrically connected to the second shielding electrode SE2 on the second substrate SUB2 side via the conductive beads 31 included in the sealing material 30 can be reduced.

[0125] In more detail, the detection electrode Rx has a plurality of mesh-like thin line portions in the first area A1, thereby reducing the electrode area of the detection electrode Rx exposed due to the above-mentioned cracks and reducing the risk of short circuit caused by the electrical connection between the detection electrode Rx and the second shielding electrode SE2 via the conductive beads 31.

[0126] Furthermore, by configuring the detection electrode Rx in the first area A1 as a mesh of multiple thin lines, the overall electrode area of the detection electrode Rx can be reduced. This reduces the capacitance added when an external proximity object such as a finger touches the display device Rx, and the time constant can be correspondingly shortened. In other words, the display device DSP2 according to this embodiment, like the display device DSP1 according to the first embodiment, can detect touches by external proximity objects such as fingers within a short period of time.

[0127] Here, as a modification of the present embodiment, another shape of the detection electrode Rx that can reduce the risk of electrical connection between the detection electrode Rx and the second shield electrode SE2 via the conductive beads 31 in the first area A1 will be described.

[0128] (Modification of the Second Embodiment)

[0129] Figure 16 1 is a top view showing the shape of the detection electrode Rx involved in the modification. Figure 16 In the figure, the interlayer insulating film 12 and the sealing material 30 are omitted. Figure 16 As shown, in the first area A1, the detection electrode Rx may also have multiple zigzag-shaped thin lines. The multiple zigzag-shaped thin lines are arranged at predetermined intervals and are formed so as not to intersect with each other. Preferably, the predetermined interval, i.e., the interval between one zigzag-shaped thin line and other adjacent zigzag-shaped thin lines, is larger than the diameter of the conductive beads 31 included in the sealing material 30.

[0130] exist Figure 16 In the illustrated shape, the electrode area of the detection electrode Rx exposed by the crack in the first region A1 can be made smaller than when the second region A2 is formed into a flat plate-like structure, for example, so that the same effect as described above can be obtained.

[0131] Furthermore, in the first area A1, the detection electrode Rx may have multiple linear or wavy thin line portions instead of the aforementioned zigzag thin line portions. In either case, the electrode area of the detection electrode Rx in the first area A1 can be made smaller than when the second area A2 is formed as a flat plate, and this point remains unchanged, thereby achieving the same effect as described above.

[0132] In the embodiment described above, in the first area A1, where there is a risk of electrical connection between the detection electrode Rx and the second shielding electrode SE2 via the conductive beads 31, the detection electrode Rx has a shape consisting of multiple thin lines, thereby reducing this risk. However, from the perspective of reducing this risk, the second shielding electrode SE2, rather than the detection electrode Rx, may have a shape consisting of multiple thin lines in the first area A1. That is, the second shielding electrode SE2 may have multiple thin lines in the first area A1 in a mesh pattern, a zigzag pattern, a straight pattern, or a wavy pattern.

[0133] Even in this case, since the electrode area of the second shield electrode SE2 overlapping with the detection electrode Rx in a plan view in the first area A1 can be reduced, the above-mentioned risk can be reduced, and the same effect as the above-mentioned effect can be obtained.

[0134] In addition, from the perspective of reducing the above-mentioned risk, both the detection electrode Rx and the second shielding electrode SE2 may have a shape consisting of a plurality of thin line portions in the first area A1. Figure 17 As shown in FIG. 1 , it is preferable that the plurality of thin line portions of the detection electrode Rx and the plurality of thin line portions of the second shielding electrode SE2 are formed so as not to overlap when viewed from above. Figure 17 In, with Figure 16 Likewise, illustration of the interlayer insulating film 12 and the sealing material 30 is omitted.

[0135] Therefore, it is preferred that the multiple thin line portions of the detection electrode Rx and the multiple thin line portions of the second shielding electrode SE2 are not formed into a mesh shape, but are formed into a zigzag line shape, a straight line shape, or a wavy line shape. Thus, in the first area A1, the detection electrode Rx and the second shielding electrode SE2 do not overlap when viewed from above, so even if the detection electrode Rx is exposed due to the above-mentioned cracks, the detection electrode Rx and the second shielding electrode SE2 will not be electrically connected via the conductive beads 31, and the above-mentioned risks can be eliminated. The fact that the detection electrode Rx and the second shielding electrode SE2 do not overlap when viewed from above includes the following situations: the detection electrode Rx and the second shielding electrode SE2 are alternately arranged when viewed from above; and the thin line portion of one electrode is arranged between the thin line portions of the other electrode when viewed from above. In addition, as Figure 17 As shown, the tip of the thin line portion of the detection electrode Rx may not be connected to any place (any component). In addition, the tip of the thin line portion of the detection electrode Rx may not overlap with the second shielding electrode SE2 located in the second area A2 in a plan view.

[0136] The display device DSP2 according to the second embodiment described above has a structure in which, in a first region A1 where the detection electrode Rx, the interlayer insulating film 12, the sealing material 30, and the second shield electrode SE2 overlap in a plan view, at least one of the detection electrode Rx and the second shield electrode SE2 has a shape consisting of multiple thin line portions. This structure reduces the risk of a short circuit between the detection electrode Rx and the second shield electrode SE2, resulting from electrical connection via the conductive beads 31 included in the sealing material 30, during the manufacturing process of the display device DSP2, even if a crack develops in the interlayer insulating film 12 covering the detection electrode Rx, exposing a portion of the detection electrode Rx.

[0137] Figure 18 1 shows an application example of the display device DSP involved in each embodiment. Figure 18 As shown, the display device DSP is applied to, for example, a wristwatch 100. In this case, the time and the like are displayed on the display area DA of the display device DSP. The display device DSP detects a predetermined gesture (e.g., a gesture of touching the outer periphery of the watch in a clockwise rotation, a gesture of touching the outer periphery of the watch in a counterclockwise rotation, a tapping gesture, etc.) by touching the detection electrodes arranged in the peripheral area SA, and can perform an action corresponding to the detected predetermined gesture.

[0138] Figure 19 Other application examples of the display device DSP involved in each embodiment are shown. Figure 19 As shown, the display device DSP is applied to, for example, a vehicle rearview mirror 200. In this case, an image of the rear of the vehicle captured by a camera installed in the vehicle is displayed on the display area DA of the display device DSP. The display device DSP detects a predetermined gesture by touching detection electrodes arranged in the peripheral area SA, and can perform an action corresponding to the detected predetermined gesture.

[0139] Figure 20 This is a diagram illustrating an example of the principle of touch detection using a self-capacitance method. The voltage of the power supply Vdd is divided by a resistor divider and supplied to the detection electrode Rx as a bias voltage. A driving signal of a predetermined waveform is supplied from the driving circuit 300b to the detection electrode Rx through capacitive coupling, etc., and a detection signal of a predetermined waveform is read from the detection electrode Rx. At this time, if the capacitance generated by a finger or the like is applied to the detection electrode Rx, the amplitude of the detection electrode changes. Figure 20 In the case of Figure 20 In the equivalent circuit shown, the presence or absence of contact or approach of an external object such as a finger is detected by detecting the amplitude of the detection electrode Rx using the detection circuit 400b. Figure 20The circuit shown may adopt any circuit method as long as it can detect the presence of an external approaching object such as a finger using only the detection electrodes.

[0140] According to at least one embodiment described above, a display device can be provided that can reduce the risk of unintended electrical connection between components during the manufacturing process.
