Although not illustrated, a protective cover for protecting the touch panel sensor 20 and the display device 15 may be provided on the observer side of the touch panel sensor 20.

Touch Panel Sensor Next, the touch panel sensor 20 will be described with reference to FIGS. 1 and 2. FIG. 2 is a plan view showing the touch panel sensor 20 when viewed from the display device 15 side. The touch panel sensor 20 is configured as a mutual capacitive touch panel sensor.

  As shown in FIGS. 1 and 2, the touch panel sensor 20 includes a rectangular base material 22 including a first surface 22 a on the display device 15 side and a second surface 22 b on the observer side. The base material 22 includes a rectangular first region Aa1 corresponding to a region where the position of the external conductor can be detected, and a rectangular frame-shaped second region Aa2 positioned around the first region Aa1. As shown in FIG. 2, the touch panel sensor 20 includes a plurality of sensor units 24, a plurality of first wirings 26, and a plurality of second wirings 28. The sensor unit 24, a part of the first wiring 26, and a part of the second wiring 28 are arranged in the first region Aa1 of the base material 22, and the other part of the first wiring 26 and the other of the second wiring 28 are arranged. Is disposed in the second region Aa2 of the base material 22. The sensor unit 24, the first wiring 26, and the second wiring 28 are all provided on the same surface of the base material 22. For example, the sensor unit 24, the first wiring 26, and the second wiring 28 are all provided on the first surface 22 a of the base material 22. In addition, all of the sensor unit 24, the first wiring 26, and the second wiring 28 may be provided on the second surface 22 b of the base material 22.

(Base material)
As a material constituting the base material 22, for example, a material having sufficient translucency such as an organic material such as polyethylene terephthalate (PET) or cycloolefin polymer (COP) or an inorganic material such as glass is used. When the base material 22 contains organic materials, such as PET, the thickness of the base material 22 is 30 micrometers or more and 200 micrometers or less, for example, Preferably they are 30 micrometers or more and 100 micrometers or less. In addition, as long as the sensor part 24, the 1st wiring 26, and the 2nd wiring 28 can be hold | maintained appropriately, the specific structure of the base material 22 is not specifically limited. For example, the base material 22 may further include a hard coat layer provided on the surface of the PET film.

(Sensor part)
As shown in FIG. 2, the plurality of sensor units 24 are two-dimensionally arranged on the first surface 22 a of the base material 22. For example, the plurality of sensor units 24 are arranged along the first direction D1 and the second direction D2 that intersects the first direction D1. In the example shown in FIG. 2, the second direction D2 is orthogonal to the first direction D1. In the following description, the sensor unit 24 located at the mth position in the first direction D1 and nth position in the second direction D2 is also referred to as a sensor portion 24_mn. m and n are arbitrary positive integers.

  FIG. 3 is an enlarged plan view showing a part of the plurality of sensor units 24 of the touch panel sensor 20 shown in FIG. 2, for example, the sensor unit 24_31, the sensor unit 24_41, the sensor unit 24_32, and the sensor unit 24_42. The sensor unit 24 includes a first electrode 30 and a second electrode 40 that face each other. One of the first electrode 30 and the second electrode 40 functions as a drive electrode to which a signal voltage is applied, and the other functions as a detection electrode. For example, when the first electrode 30 is a drive electrode, the second electrode 40 functions as a detection electrode. In this case, the signal voltage from the first electrode 30 is transmitted to the second electrode 40 by capacitive coupling via a capacitor formed between the first electrode 30 and the second electrode 40.

  The first electrode 30 includes a plurality of first linear portions 31 and a first connection portion 32 connected to the plurality of first linear portions 31. The multiple first linear portions 31 extend in the third direction D3 and are arranged in a sixth direction D6 that intersects the third direction D3. In the example shown in FIG. 3, the sixth direction D6 is orthogonal to the third direction D3. The third direction D3 is parallel to the first direction D1 described above. In other words, the third direction D3 is orthogonal to the second direction D2. The sixth direction D6 is parallel to the second direction D2. Each first linear portion 31 includes a pair of side portions 311 extending in the third direction D3. The first connection portion 32 extends in the sixth direction D6. The first connection portion 32 includes a pair of side portions 321 extending in the sixth direction D6.

  Similar to the first electrode 30, the second electrode 40 also includes a plurality of second linear portions 41 and a second connection portion 42 connected to the plurality of second linear portions 41. The plurality of second linear portions 41 extend in the third direction D3 and are arranged in a sixth direction D6 that intersects the third direction D3. Each second linear portion 41 includes a pair of side portions 411 extending in the third direction D3. The second linear portion 41 is located between the two adjacent first linear portions 31. For example, the first linear portions 31 and the second linear portions 41 are alternately arranged along the sixth direction D6. In the example shown in FIG. 3, the same number of first linear portions 31 and second linear portions 41 are alternately arranged. Further, the second connection portion 42 extends in the sixth direction D6. The second connection portion 42 includes a pair of side portions 421 extending in the sixth direction D6.

  As shown in FIG. 3, the side portion 311 of each first linear portion 31 faces the side portion 411 of each second linear portion 41. In this case, a capacitance proportional to the length of the side portion 311 and the opposing portion of the side portion 411 is provided between the side portion 311 of the first linear portion 31 and the side portion 411 of the second linear portion 41. A capacitor is formed. Therefore, the distance between the first electrode 30 and the second electrode 40 is proportional to the number of the first linear portions 31 and the second linear portions 41 and the lengths of the opposing portions of the side portions 311 and the side portions 411. A capacitor having a capacitance is formed. For this reason, compared with the above-mentioned patent document 1, compared with the case where it opposes only at the edge part of a drive electrode and a detection electrode, an electrostatic capacitance can be increased. As a result, the detection sensitivity of the sensor unit 24 can be increased.

(First wiring)
Next, the first wiring 26 will be described. As shown in FIGS. 2 and 3, each of the plurality of first wirings 26 is connected to the first electrode 30 of the corresponding one of the plurality of sensor units 24 arranged in the first direction D1. . The first wiring 26 includes a connection portion 261 and a linear portion 262. The connection portion 261 is connected to the first connection portion 32 of the corresponding first electrode 30 on one side in the sixth direction D6 (left side in the example of FIG. 3). The linear portion 262 extends from the connection portion 261 to the second region Aa2. Both the connecting portion 261 and the linear portion 262 extend in the first direction D1 in which the plurality of sensor portions 24 are arranged.

  The width in the second direction D2 of the connection portion 261 of the first wiring 26 connected to the first electrode 30 of one of the two sensor parts 24 adjacent in the first direction D1 is the other sensor. The width of the connecting portion 261 of the first wiring 26 connected to the first electrode 30 of the portion 24 may be different from the width in the second direction D2. For example, as illustrated in FIG. 3, the width of the connection portion 261 connected to the first electrode 30 of the sensor unit 24_31 in the second direction D2 is the width of the connection portion 261 connected to the first electrode 30 of the sensor unit 24_41. The width in the second direction D2 may be larger. Hereinafter, the reason for such a configuration will be described.

  As shown in FIG. 2, the plurality of linear portions 262 of the first wiring 26 connected to the plurality of sensor units 24 arranged in the first direction D1 are arranged in the second direction D2. In this case, the number of the linear portions 262 arranged in the second direction D2 increases as it approaches the lower second region Aa2 (the second region Aa2 located in the direction toward the linear portion 262) in FIG. Here, in the present embodiment, as shown in FIG. 2, the connection portion 261 having a larger distance to the second region Aa2 in the first direction D1 has a larger width in the second direction D2. As a result, as shown in FIG. 2, the width of the region occupied by the first wiring 26 in the second direction D2 can be made constant regardless of the position in the first direction D1. For this reason, since the width of the sensor unit 24 in the second direction D2 can be made constant regardless of the position in the first direction D1, it is possible to suppress the sensitivity of the sensor unit 24 from being different depending on the position in the first direction D1. can do.

(Second wiring)

As shown in FIGS. 2 and 3, each of the plurality of second wirings 28 is connected to the second connection portion 42 of the corresponding second electrode 40 on one side in the sixth direction D6 (in the example of FIGS. 2 and 3). On the right). The second wiring 28 faces the connection portion 261 of the first wiring 26 via the sensor unit 24 in the sixth direction D6. The second wiring 28 extends to the second region Aa2 along the first direction D1 in which the plurality of sensor units 24 are arranged.

  As shown in FIGS. 2 and 3, one second wiring 28 may be connected to the second electrodes 40 of the plurality of sensor units 24 arranged in the first direction D1. Thereby, the number of the second wirings 28 arranged in the first area Aa1 can be reduced.

  Hereinafter, the configuration of the first electrode 30, the second electrode 40, the first wiring 26, and the second wiring 28 will be described in detail.

It is comprised by removing as a part. Thus, the conspicuous gap S1 can be suppressed.

  Similarly, in the first wiring 26 and the second wiring 28, 90% or more of the fourth direction wiring conductors 814 a and 814 b are extended lines L 4 of the first electrode 30 of the fourth direction electrode conductor 614 a. It is arranged to overlap. In addition, the first wiring 26 and the second wiring 28 include 90% or more of the fifth direction wiring conductors 815a and 815b and the extension line L5 of the first electrode 30 which is one of the fifth direction electrode conductors 615a. They are arranged so as to overlap. For example, the gaps S2 and S3 are portions of one conductor wire 614a, 814a, 814b extending linearly or a portion of the conductor wires 615a, 815a, 815b that is located in the region to be the gap S2, S3 (the extension line L4 in FIG. 5). It is comprised by removing the part shown as L5 as a parting part. Thus, the conspicuous gaps S2 and S3 can be suppressed.

  4 and 5, the alternate long and short dash line is a line drawn virtually to show the outline of the component of the display device with a touch position detection function 10 such as the first linear portion 31. The outline of each component is defined by lines connecting the ends of the conductors 614a, 614b, 615a, 615b, 814a, 814b, 815a, 815b. For example, as shown in FIG. 5, the outline of the side portion 311 of the first linear portion 31 is defined by a line connecting the ends of the plurality of conducting wires 614a and 615a arranged along the third direction D3.

  In the first linear portion 31 and the second linear portion 41 extending in the third direction D3, preferably, an intersection 61a where the conductive wires 614a, 615a, 615b, and 615b of the electrode conductive wire network 61 intersect with each other in the third direction D3. At least two or more are arranged along the orthogonal direction (here, the sixth direction D6). In this case, even if one intersection 61a is removed due to an etching defect or the like during manufacturing, at least one intersection 61a remains in the first linear portion 31 and the second linear portion 41. be able to. Therefore, a signal can be given to the first linear portion 31 and the second linear portion 41 along the third direction D3 by using at least one remaining intersection 61a. Thereby, the possibility that the first linear portion 31 and the second linear portion 41 are disconnected can be reduced.

  Similarly, in the first wiring 26 and the second wiring 28 extending in the first direction D1, preferably, an intersection point 81a where the conductors 814a, 815a, 814b, and 815b intersect is a direction orthogonal to the first direction D1 (here, the first direction D1). Two or more are arranged along the two directions D2). Thereby, the possibility that the first wiring 26 and the second wiring 28 are disconnected can be reduced.

  FIG. 6 is a diagram illustrating an example of a cross-sectional structure of the touch panel sensor 20. As shown in FIG. 6, the wire nets 61 and 81 include metal layers 64 and 84 provided on the first surface 22 a of the base material 22. The metal layers 64 and 84 include, for example, silver, copper, aluminum, or an alloy thereof. The widths of the metal layers 64 and 84 are set according to the required aperture ratio or the like, and are, for example, 1 μm or more and 10 μm or less. The thickness of the metal layers 64 and 84 is appropriately set according to the electrical resistance value required for the first electrode 30 and the second electrode 40, and is, for example, 0.1 μm or more and 5.0 μm or less. The metal layers 64 and 84 shown in FIG. 6 are obtained, for example, by patterning a metal layer provided over the entire area on the first surface 22a of the base material 22 by etching or the like.

  Although not shown in the figure, the conductor nets 61 and 81 may be subjected to low reflection processing for suppressing light reflection by the conductor nets 61 and 81. For example, the surface of the metal layers 64 and 84 may be blackened. In addition, the conductive wire nets 61 and 81 may further include a low reflection layer positioned between the metal layers 64 and 84 and the first surface 22a of the substrate 22.

(Effect of this embodiment)
According to the present embodiment, as described above, the first electrode 30 and the second electrode 40 of the sensor unit 24 each include a plurality of first linear portions 31 and second linear portions 41 that face each other. Therefore, a capacitor having a capacitance proportional to the number of the first linear portions 31 and the second linear portions 41 can be formed between the first electrode 30 and the second electrode 40. For this reason, the electrostatic capacitance of the sensor unit 24 can be increased, and thereby the detection sensitivity of the sensor unit 24 can be increased.

  In the present embodiment, the electrode wire network 61 for the first electrode 30 and the second electrode includes a plurality of fourth direction electrode lead wires 614a and 614b extending linearly along the fourth direction D4, and the fourth direction. A plurality of fifth-direction electrode lead wires 615a and 615b extending linearly along a fifth direction D5 intersecting D4. Further, 90% or more of the fourth direction electrode conductor 614b of the second electrode 40 overlaps with any one of the extended lines L4 of the fourth direction electrode conductor 614a of the first electrode 30. Also. 90% or more of the fifth-direction electrode conducting wire 615b of the second electrode 40 overlaps with any extension line L5 of the fifth-direction electrode conducting wire 615a of the first electrode 30. Thereby, it is possible to suppress the conspicuous gap S1 between the first electrode 30 and the second electrode 40.

  In the present embodiment, each of the first wiring 26 and the second wiring 28 is a wiring conductor network 81 having a mesh pattern, and includes a plurality of lines extending linearly along the fourth direction D4. There are fourth direction wiring conductors 814a and 814b and a plurality of fifth direction wiring conductors 815a and 815b extending linearly along the fifth direction D5. Further, 90% or more of the fourth direction wiring conductors 814a and 814b of the first wiring 26 and the second wiring 28 overlap with any one of the extension lines L4 of the fourth direction electrode conductor 614a of the first electrode 30. Further, 90% or more of the fifth-direction wiring conductors 815a and 815b of the first wiring 26 and the second wiring 28 overlap with any one of the extension lines L5 of the fifth-direction electrode conductor 615a of the first electrode 30. Thus, the gap S2 between the first electrode 30 and the second electrode 40, the first wiring 26 and the second wiring 28, and the gap S3 between the first wiring 26 and the second wiring 28, Can be conspicuous.

  Further, in the present embodiment, in each of the first linear portion 31 of the first electrode 30 and the second linear portion 41 of the second electrode 40, the fourth direction electrode lead wires 614a and 614b and the fifth direction electrode use are provided. At least two intersections 61a of the conducting wires 615a and 615b are arranged along a direction orthogonal to the third direction D3 in which the first linear portion 31 and the second linear portion 41 of the second electrode 40 extend. As a result, even if one intersection 61a is removed due to an etching defect or the like during manufacturing, at least one intersection 61a is left in the first linear portion 31 and the second linear portion 41. be able to. Therefore, a signal can be given to the first linear portion 31 and the second linear portion 41 along the third direction D3 by using at least one remaining intersection 61a. Thereby, the possibility that the first linear portion 31 and the second linear portion 41 are disconnected can be reduced.

  In the present embodiment, in each of the plurality of first wirings 26 extending in the first direction D1 and arranged in the second direction D2 in the first region Aa1, the fourth direction wiring conductor 814a and the fifth direction electrode are used. At least two intersections 81a of the conducting wires 815a are arranged along a direction orthogonal to the first direction D1 in which the first wiring 26 extends. As a result, even if one intersection 81a is removed due to an etching defect during manufacturing, at least one intersection 81a can be left in the first wiring 26. Accordingly, a signal can be given to the first wiring 26 along the first direction D1 by using at least one remaining intersection 81a. Thereby, the possibility that the first wiring 26 is disconnected can be reduced.

[Second Embodiment]
The second embodiment will be described below with reference to FIGS. The second embodiment is different only in that the sensor unit 24 further includes a dummy electrode 50, and other configurations are substantially the same as those of the first embodiment. In the second embodiment, the same parts as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. Moreover, when it is clear that the effect obtained in the first embodiment can be obtained in the present embodiment, the description thereof may be omitted.

  FIG. 7 is an enlarged plan view showing a part of the touch panel sensor 20 according to the present embodiment. As shown in FIG. 7, the sensor unit 24 further includes a dummy electrode 50 that is not connected to either the first electrode 30 or the second electrode 40.

  FIG. 8 is a plan view showing the sensor unit 24 and the first wiring 26 in FIG. As shown in FIGS. 7 and 8, the dummy electrode 50 is located between the first linear portion 31 and the second linear portion 41.

  As shown in FIGS. 7 and 8, in this modification, the first gap S1 extending in the third direction D3 in the sensor unit 24 is between the first linear portion 31 and the dummy electrode 50, and the second line. Formed between the shaped portion 41 and the dummy electrode 50. In FIG. 8, the symbol d represents the distance between the side portion 311 of the first linear portion 31 and the side portion 411 of the second linear portion 41 in the sixth direction D6. According to the present embodiment, by providing the dummy electrode 50, the distance d between the first linear portion 31 and the second linear portion 41 can be increased.

  9 and 10 are diagrams for explaining an effect realized by increasing the distance d between the first linear portion 31 and the second linear portion 41. FIG. FIG. 9 is a cross-sectional view illustrating an example of the sensor unit 24 when the dummy electrode 50 is not present, and FIG. 10 is a cross-sectional view illustrating an example of the sensor unit 24 when the dummy electrode 50 is present.

  9 and 10, reference numeral 71 represents a line of electric force formed between the first linear portion 31 and the second linear portion 41. The electric lines of force 71 spread over a wider area as the distance d between the first linear portion 31 and the second linear portion 41 is larger. The greater the range in which the lines of electric force 71 are spread, the wider the range in which the sensor unit 24 can detect the external conductor 72. For example, the distance E between the second surface 22 b of the base material 22 and the outer conductor 72 when the sensor unit 24 starts to detect the outer conductor 72 is increased. That is, the sensitivity of the sensor unit 24 is improved.

  In the example shown in FIG. 9, the interval d is equal to the width a of the first gap S1. Increasing the width a of the first gap S1 makes it easier for the user to visually recognize the first gap S1. For this reason, in the example shown in FIG. 9, the distance d is limited, and as a result, the sensitivity of the sensor unit 24 is also limited.

  On the other hand, in the example shown in FIG. 10, the interval d is obtained by adding the width of the dummy electrode 50 to a value obtained by doubling the width a of the first gap S1. According to the example shown in FIG. 10, the distance d can be increased while maintaining the width a of the first gap S1, and the sensitivity of the sensor unit 24 can be improved. For example, the distance E between the second surface 22b of the base material 22 and the external conductor 72 when the sensor unit 24 starts to detect the external conductor 72 may be made larger than in the example shown in FIG. it can. Thereby, for example, even when the thickness of the base material 22 is large or when a protective cover or the like is further provided on the second surface 22b side of the base material 22, the external conductor 72 can be detected appropriately.

  Further, in the example shown in FIG. 8, the dummy electrode 50 includes a dummy electrode conducting wire network 51 having a mesh pattern, like the first linear portion 31 and the second linear portion 41. The dummy electrode wire network 51 includes a plurality of fourth direction dummy electrode conductors 514 extending linearly along the fourth direction D4 and a plurality of fifth direction dummy electrodes extending linearly along the fifth direction D5. A conductive wire 515. The fourth-direction dummy electrode conductor 514 is arranged such that 90% or more of the fourth-direction dummy electrode conductor 514 overlaps any extension line L4 of the fourth-direction electrode conductor 614a of the first electrode 30. Further, the fifth direction dummy electrode conducting wire 515 is arranged such that 90% or more of the fifth direction dummy electrode conducting wire 515 overlaps any extension line L5 of the fifth direction electrode conducting wire 615a of the first electrode. Thus, the conspicuous gap S1 between the first electrode 30 and the second electrode 40 and the dummy electrode 50 can be suppressed.

[Third Embodiment]
Hereinafter, a third embodiment will be described with reference to FIG. The third embodiment is different only in the angle of the conductive wire constituting the electrode conductive wire network, the wiring conductive wire network, and the dummy electrode conductive wire network, and the other configuration is substantially the same as the second exemplary embodiment. . In the third embodiment, the same parts as those in the second embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. In addition, when it is clear that the effects obtained in the second embodiment can be obtained in the present embodiment, the description thereof may be omitted.

  FIG. 11 is an enlarged plan view showing a part of the touch panel sensor 20 according to the present embodiment, in particular, the sensor unit 24 and the first wiring 26. In the example shown in FIG. 11, the fourth direction D4 in which the conductive wires 614a and 614b extend and the fifth direction D5 in which the conductive wires 615a and 615b extend are the third directions in which the first linear portion 31 and the second linear portion 41 extend. The angles θ1 and θ2 formed with respect to the direction D3 are smaller than 45 °. For this reason, the dimension h3 in the third direction D3 of each opening 62 defined by the electrode wire network 61 is a dimension in a direction orthogonal to the third direction D3 of the opening 62 (here, the sixth direction D6). Greater than h6.

  According to the present embodiment, the distance between the intersection points 61a in the direction orthogonal to the third direction D3 (here, the sixth direction D6) of the conductors 614a and 614b and the conductors 615a and 615b is the distance between the intersection points 61a in the third direction D3. Smaller than. Therefore, the direction perpendicular to the third direction D3 with respect to the dimension in the third direction D3 of the first linear portion 31 and the second linear portion 41 of the first electrode 30 and the second electrode 40 (here, the sixth direction D6). ) In the first linear portion 31 and the second linear portion 41, the intersection 61a of the fourth direction electrode conductors 614a and 614b and the fifth direction electrode conductor wires 615a and 615b is It is possible to arrange at least two or more along the direction orthogonal to the third direction D3. Accordingly, the first linear portion 31 and the second linear portion 41 of each sensor unit 24 are made thinner while reducing the possibility that the first linear portion 31 and the second linear portion 41 are disconnected. The number of the first linear portions 31 and the second linear portions 41 can be increased. As a result, the length of the opposing portion of the side portion 311 of the first linear portion 31 and the side portion 411 of the second linear portion 41 in each sensor unit 24 is increased, and the capacitance is increased.

  In the example shown in FIG. 11, the fourth direction D4 in which the conducting wire 814a of the first wiring 26 extends and the fifth direction D5 in which the conducting wire 815a of the first wiring 26 extends are in the first direction D1 in which the sensor units 24 are arranged. Are made smaller than 45 °. For this reason, the dimension h1 in the first direction D1 of each opening 82 defined by the wiring network 81 for wiring is a dimension in a direction orthogonal to the first direction D1 of the opening 82 (here, the second direction D2). Greater than h2.

  According to the present embodiment, the distance between the intersection points 81a in the direction orthogonal to the first direction D1 (here, the second direction D2) of the conductors 814 and 815 is smaller than the distance between the intersection points 81a in the first direction D1. Therefore, even if the dimension in the direction perpendicular to the first direction D1 (here, the second direction D2) is smaller than the dimension in the first direction D1 of the first wiring 26 in the first region Aa1, the first wiring 26 In each, at least two or more intersections 81a of the fourth direction wiring conductor 814a and the fifth direction wiring conductor 815a can be arranged along the direction orthogonal to the first direction D1. Thereby, it is possible to make the 1st wiring 26 thin, reducing the possibility that the 1st wiring 26 will be disconnected. As a result, the area occupied by the first wiring 26 in the first region Aa1 can be reduced, and thereby the area occupied by the sensor unit 24 in the first region Aa1 can be increased.

  Furthermore, in the example shown in FIG. 11, the first direction in which the sensor unit 24 is arranged is the fourth direction D4 in which the conducting wires 614a, 614b, 514, 814 extend and the fifth direction D5 in which the conducting wires 615a, 615b, 515, 815 extend. The angles θ1 and θ2 formed with respect to the direction D1 are 10 ° to 45 °.

  According to the present embodiment, when the touch panel sensor 20 and the display device 15 illustrated in FIG. 11 are combined, the first direction D1 in which the sensor units 24 of the touch panel sensor 20 are arranged and the pixels regularly arranged on the display device 15 are arranged. The effect of suppressing moiré can be expected by matching the arrangement direction of the two. In addition, the effect which suppresses moire has the 4th direction D4 from which conducting wire 614a, 614b, 514, 814 extends, or the 5th direction D5 from which conducting wire 615a, 615b, 515, 815 extends, and the 1st direction where the sensor part 24 is located in a line. This is most noticeable when the angle formed by D1 is 35 °.

[Fourth Embodiment]
Hereinafter, a fourth embodiment will be described with reference to FIG. In the fourth embodiment, only the angles of the conductors constituting the electrode conductor network, the wiring conductor network, and the dummy electrode conductor network are different, and the other configurations are substantially the same as those of the second embodiment. . In the fourth embodiment, the same parts as those in the second embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. In addition, when it is clear that the effects obtained in the second embodiment can be obtained in the present embodiment, the description thereof may be omitted.

  FIG. 12 is an enlarged plan view showing a part of the touch panel sensor 20 according to the present embodiment, in particular, the sensor unit 24 and the first wiring 26. In the example shown in FIG. 12, the angle ψ1 formed by the fourth direction D4 in which the conducting wires 614a, 614b, 514, 814a, and 814b extend and the first direction D1 in which the sensor portions 24 are arranged, and the conducting wires 615a, 615b, and 515 are formed. , 815a and 815b, and an angle ψ2 formed by the first direction D1 in which the sensor portions 24 are arranged are in the range of 45 ° to 80 °.

  According to the present embodiment, when the touch panel sensor 20 and the display device 15 illustrated in FIG. 12 are combined, the first direction D1 in which the sensor units 24 of the touch panel sensor 20 are arranged and the pixels regularly arranged on the display device 15 are arranged. The effect of suppressing moiré can be expected by matching the arrangement direction of the two. The effect of suppressing moire is that the sensor unit 24 has a fourth direction D4 in which the conductive wires 614a, 614b, 514, 814a, and 814b extend, or a fifth direction D5 in which the conductive wires 615a, 615b, 515, 815a, and 815b extend. This is most noticeable when the angles ψ1 and ψ2 formed by the first direction D1 that are arranged are 55 °.

Hereinafter, a fifth embodiment will be described with reference to FIG. In the fifth embodiment, only the angle formed between the third direction in which the first linear portion of the first electrode extends and the first direction in which the first wiring extends is different, and the other configuration is the second configuration. This is substantially the same as the embodiment. In the fifth embodiment, the same parts as those in the second embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. In addition, when it is clear that the effects obtained in the second embodiment can be obtained in the present embodiment, the description thereof may be omitted.

In the example shown in FIG. 13, the third direction D3 in which the first linear portion 31 extends does not coincide with the first direction D1 in which the first wiring 26 extends.
