実施の形態によるタッチセンサ５０１は静電容量式のタッチセンサである。タッチセンサ５０１は、図１Ａに示すように、基材部１０とセンサ電極２０を有する。基材部１０は薄板形状を有するポリカーボネイト（ＰＣ）樹脂等の絶縁材料製である。センサ電極２０は基材部１０の表面１０Ａのみに配置されており、送信電極２２と受信電極２４とを含む。基材部１０の表面１０Ａはセンサ電極２０が設けられている配置面１０Ｐであり、センサ電極２０は配置面１０Ｐ内に設けられている。基材部１０の表面１０Ａの反対側の表面１０Ｂには電極は配置されていない。 The touch sensor 501 according to the embodiment is a capacitive touch sensor. As shown in FIG. 1A, the touch sensor 501 includes a base member 10 and a sensor electrode 20. The base member 10 is made of an insulating material such as a polycarbonate (PC) resin having a thin plate shape. The sensor electrode 20 is disposed only on the surface 10A of the base member 10 and includes a transmission electrode 22 and a reception electrode 24. The surface 10A of the base member 10 is an arrangement surface 10P on which the sensor electrode 20 is provided, and the sensor electrode 20 is provided in the arrangement surface 10P. No electrode is disposed on the surface 10B opposite to the surface 10A of the base member 10.

図２は図１Ａに示す領域Ａ１の拡大図であり、センサ電極２０の外形を示す。送信電極２２と受信電極２４の外形は線状の分離部３０で画定されている。送信電極２２と受信電極２４は、配置面１０Ｐ内にネット形状を構成するように配置された複数の導電細線よりなる。図３は配置面１０Ｐ内に配置された導電細線１１をセンサ電極２０と共に示す。送信電極２２と受信電極２４との間には送信電極２２と受信電極２４とを互いに絶縁するダミーパターンが配置されている。送信電極２２は領域９０に配置されている。受信電極２４は領域４０に配置されている。送信電極２２の櫛歯部と受信電極２４の櫛歯部との間に配置されたダミーパターンは領域４０、９０の間の領域５０に配置されている。 FIG. 2 is an enlarged view of the area A1 shown in FIG. The outer shapes of the transmitting electrode 22 and the receiving electrode 24 are defined by a linear separating portion 30. The transmission electrode 22 and the reception electrode 24 are composed of a plurality of conductive wires arranged so as to form a net shape in the arrangement surface 10P. FIG. 3 shows the conductive thin wires 11 arranged in the arrangement surface 10 P together with the sensor electrodes 20. A dummy pattern is provided between the transmission electrode 22 and the reception electrode 24 to insulate the transmission electrode 22 and the reception electrode 24 from each other. The transmission electrode 22 is arranged in the region 90. The receiving electrode 24 is arranged in the area 40. The dummy pattern arranged between the comb teeth of the transmission electrode 22 and the comb teeth of the reception electrode 24 is arranged in an area 50 between the areas 40 and 90.

図３に示すように、導電細線１１は、複数のメッシュ１９を有するネット状に配置されている。複数のメッシュ１９は互いに繋がっていて、領域４０に位置する複数のメッシュ４９と、領域５０に位置する複数のメッシュ５９と、分離部３０に位置する複数のメッシュ３９とを含む。複数の導電細線１１は、複数のメッシュ４９を画定するように領域４０に位置する複数の導電細線４１と、複数のメッシュ５９を画定するように領域５０に位置する複数の導電細線５１とを含む。領域４０では、導電細線４１（１１）が複数のメッシュ４９を有するネット状に配置されている。領域５０では、導電細線５１（１１）が複数のメッシュ５９を有するネット状に配置されている。導電細線１１の幅は例えば５μｍ以下であり、好ましくは２μｍ程度である。導電細線１１は銅などの金属等の導電材料で形成されている。実施の形態では、メッシュ１９はひし形状を有する。 As shown in FIG. 3, the conductive fine wires 11 are arranged in a net shape having a plurality of meshes 19. The plurality of meshes 19 are connected to each other, and include a plurality of meshes 49 located in the area 40, a plurality of meshes 59 located in the area 50, and a plurality of meshes 39 located in the separation unit 30. The plurality of conductive thin lines 11 include a plurality of conductive thin lines 41 located in the region 40 so as to define a plurality of meshes 49 and a plurality of conductive thin lines 51 located in the region 50 so as to define a plurality of meshes 59. . In the region 40, the conductive thin wires 41 (11) are arranged in a net shape having a plurality of meshes 49. In the region 50, the conductive fine wires 51 (11) are arranged in a net shape having a plurality of meshes 59. The width of the conductive fine wire 11 is, for example, 5 μm or less, and preferably about 2 μm. The conductive fine wire 11 is formed of a conductive material such as a metal such as copper. In the embodiment, the mesh 19 has a diamond shape.

領域４０、５０は分離部３０で互いに分離されており、領域５０、９０は分離部１００で互いに分離されている。分離部３０、１００は直線状に延びる。 The regions 40 and 50 are separated from each other by the separation unit 30, and the regions 50 and 90 are separated from each other by the separation unit 100. The separation parts 30 and 100 extend linearly.

図４Ａは図３に示すタッチセンサ５０１の拡大図であり、領域Ａ２を示す。配置面１０Ｐに直角の方向Ｄ１１（図１Ｂ参照）から見た平面視で、領域Ａ２における分離部３０の部分はＬ字形状を有する。領域４０は、分離部３０に面する縁端線３０Ａを有する。領域５０は、分離部３０に面してかつ分離部３０を介して縁端線３０Ａに対向する縁端線３０Ｂを有する。 FIG. 4A is an enlarged view of the touch sensor 501 shown in FIG. 3 and shows a region A2. In a plan view seen from a direction D11 perpendicular to the arrangement surface 10P (see FIG. 1B), the portion of the separation portion 30 in the region A2 has an L-shape. The region 40 has an edge line 30 A facing the separation part 30. The region 50 has an edge line 30B facing the separation portion 30 and facing the edge line 30A via the separation portion 30.

分離部３０について、さらに説明する。領域４０、５０の間の分離部３０は、メッシュ５９のひし形状の辺５９Ａの一部であって導電細線１１が欠落している欠落パターン部４５を含む。つまり、欠落パターン部４５には導電細線１１は配置されていない。複数の欠落パターン部４５が分離部３０を構成するように平面視で直線状に並べて配置されている。 The separation unit 30 will be further described. The separating portion 30 between the regions 40 and 50 includes a missing pattern portion 45 which is a part of the diamond-shaped side 59A of the mesh 59 and in which the conductive fine wire 11 is missing. That is, the conductive fine wire 11 is not arranged in the missing pattern portion 45. The plurality of missing pattern portions 45 are arranged linearly in a plan view so as to constitute the separating portion 30.

複数の導電細線４１は、縁端線３０Ａに位置する複数の端４３Ｐをそれぞれ有する複数の縁端細線４３を含む。複数の導電細線５１は、縁端線３０Ｂに位置する複数の端５３Ｐをそれぞれ有する複数の縁端細線５３を含む。領域４０には、メッシュ３９のひし形状の辺５９Ａの一部である導電細線４１（１１）の部分４７が配置されている。導電細線４１（１１）の部分４７は縁端線３０Ａ上の端４３Ｐを含む。領域５０には、メッシュ３９のひし形状の辺５９Ａの一部である導電細線５１（１１）の一部である部分５２が配置されている。導電細線５１（１１）の部分５２は縁端線３０Ｂ上の端５３Ｐを含む。メッシュ３９の辺３９Ａは、導電細線４１すなわち縁端細線４３の端４３Ｐから導電細線５１すなわち縁端細線５３の端５３Ｐまで結ぶ直線である欠落パターン部４５を含む。すなわち、対となる部分４７、５２は、対応する欠落パターン部４５を挟んで同一直線上に配置されて、欠落パターン部４５を含めてひし形状の一つの辺５９Ａを構成している。このように、分離部３０は、領域４０の分離部３０側の端４３Ｐと領域５０の分離部３０側の端５３Ｐの間に配置される導電細線１１を欠落させた欠落パターン部４５を含む。 The plurality of conductive thin lines 41 include a plurality of edge thin lines 43 each having a plurality of ends 43P located at the edge line 30A. The plurality of conductive fine lines 51 include a plurality of edge thin lines 53 each having a plurality of ends 53P located at the edge line 30B. In the region 40, a portion 47 of the conductive thin wire 41 (11), which is a part of the diamond-shaped side 59A of the mesh 39, is arranged. The portion 47 of the conductive thin wire 41 (11) includes an end 43P on the edge line 30A. In the region 50, a portion 52 that is a part of the conductive fine wire 51 (11) that is a part of the diamond-shaped side 59A of the mesh 39 is arranged. The portion 52 of the conductive wire 51 (11) includes an end 53P on the edge line 30B. The side 39A of the mesh 39 includes a missing pattern portion 45 that is a straight line connecting the conductive thin wire 41, that is, the end 43P of the edge thin wire 43, to the conductive thin wire 51, that is, the end 53P of the edge thin wire 53. That is, the paired portions 47 and 52 are arranged on the same straight line with the corresponding missing pattern portion 45 interposed therebetween, and constitute one diamond-shaped side 59A including the missing pattern portion 45. As described above, the separation portion 30 includes the missing pattern portion 45 in which the conductive fine wire 11 disposed between the end 43P of the region 40 on the separation portion 30 side and the end 53P of the region 50 on the separation portion 30 is missing.

欠落パターン部４５を介して配置されている部分４７、５２は直流的に繋がっていない。直流的に繋がっていない構成とするには、一つの辺５９Ａの中で例えば導電細線１１を部分的に取り除いて分断する、または、一つの辺５９Ａの中で導電細線１１を配置しない箇所を設ける。実施の形態では、メッシュ１９はひし形状の対向する内角ＡＧ１は６０°であり、他の対向する内角ＡＧ２は１２０°である。そのひし形状のより長い長手の対角線の長さＬ１９は２００μｍである。 The portions 47 and 52 disposed via the missing pattern portion 45 are not connected in a direct current manner. In order to make a configuration that is not connected in a direct current manner, for example, the conductive thin wire 11 is partially removed from one side 59A and cut off, or a portion where the conductive thin wire 11 is not arranged in one side 59A is provided. . In the embodiment, the mesh 19 has a diamond-shaped opposed interior angle AG1 of 60 °, and the other opposed interior angle AG2 of 120 °. The longer longitudinal diagonal length L19 of the diamond shape is 200 μm.

なお、メッシュ５９の複数の辺５９Ａの交点に欠落パターン部４５を設けると、導電細線１１の存在しない範囲が大きく生じやすい。この場合、欠落パターン部４５が視認し易くなるので、交点すなわち辺５９Ａの両端を除く辺５９Ａ内の位置に欠落パターン部４５を設けることが望ましい。 If the missing pattern portion 45 is provided at the intersection of the plurality of sides 59 A of the mesh 59, the range in which the conductive fine wire 11 does not exist is likely to be large. In this case, since the missing pattern portion 45 is easily visible, it is desirable to provide the missing pattern portion 45 at the intersection, that is, at a position within the side 59A excluding both ends of the side 59A.

図４Ａ中に示したように、分離部３０のＬ字形状の下方直線部は、紙面の左右方向に平行な方向Ｄ１０１に沿う直線形状を有する。つまり、下方直線部は、領域４０の端部位置に、同一の部分４７を配置し、かつ領域５０の端部位置に、同一の部分５２を配置することで設けられている。換言すればひし形状の長手の対角線に対する１つの垂線上に複数の欠落パターン部４５が直線上に配置されることで設けられている。なお、図４Ａ中の分離部３０のＬ字形状の左方直線部も、同様に、複数の欠落パターン部４５が紙面の上下方向に平行な方向Ｄ１０２に沿って直線上に配置することで形成される。 As shown in FIG. 4A, the L-shaped lower linear portion of the separation unit 30 has a linear shape along a direction D101 parallel to the left-right direction of the drawing. That is, the lower straight portion is provided by arranging the same portion 47 at the end position of the region 40 and arranging the same portion 52 at the end position of the region 50. In other words, the plurality of missing pattern portions 45 are provided by being arranged on a straight line on one perpendicular line to the longitudinal diagonal line of the diamond shape. Similarly, the L-shaped left straight portion of the separating portion 30 in FIG. 4A is formed by arranging a plurality of missing pattern portions 45 on a straight line along a direction D102 parallel to the vertical direction of the drawing. Is done.

欠落パターン部４５の近傍には、対応する独立細線６０（１５）が配置されている。独立細線６０は、直線形状を有して導電細線１１の部分４７、５２と同じ導電細線から構成されている。つまり、独立細線６０は部分４７および部分５２と同じ材質よりなり同じ線幅を有する。 In the vicinity of the missing pattern portion 45, a corresponding independent thin line 60 (15) is arranged. The independent fine wire 60 has the same conductive fine wire as the portions 47 and 52 of the conductive fine wire 11 having a linear shape. That is, the independent thin wire 60 is made of the same material as the portion 47 and the portion 52 and has the same line width.

図４Ｂは図４Ａに示すタッチセンサ５０１の線４Ｂ−４Ｂにおける断面図である。図４Ｂに示すように、導電細線１１（４１）と独立細線１５（６０）は共に基材部１０の配置面１０Ｐである表面１０Ａ上に設けられている。 FIG. 4B is a cross-sectional view taken along line 4B-4B of the touch sensor 501 shown in FIG. 4A. As shown in FIG. 4B, both the conductive fine wires 11 (41) and the independent fine wires 15 (60) are provided on the surface 10 A which is the arrangement surface 10 P of the base 10.

図４Ｃは図４Ａに示すタッチセンサ５０１の拡大図であり、欠落パターン部４５を示す。独立細線６０は、部分４７、５２から直流的に絶縁される位置に配置されている。すなわち、独立細線６０は、欠落パターン部４５を設けた辺の対となる部分４７、５２の間の直線からなる欠落パターン部４５に対して、近接する位置に平行関係で横にずらした位置に配置されている。独立細線６０は、欠落パターン部４５の中央位置４５Ｃを通る垂線４５Ｌ上に、独立細線６０の長さ方向での中央位置６０Ｃを合わせて配置することが望ましい。なお、独立細線６０は、図４Ａに示したように欠落パターン部４５から一定方向に平行関係でずらして配置してもよいし、部分４７、５２から直流的に絶縁状態であれば欠落パターン部４５上に配置されていてもよい。 FIG. 4C is an enlarged view of the touch sensor 501 shown in FIG. The independent thin wire 60 is arranged at a position insulated from the portions 47 and 52 in a DC manner. In other words, the independent thin line 60 is located at a position shifted laterally in a parallel relationship to a position adjacent to the missing pattern portion 45 formed of a straight line between the paired portions 47 and 52 provided with the missing pattern portion 45. Are located. It is desirable that the independent thin line 60 is arranged so that the center position 60C in the longitudinal direction of the independent thin line 60 is aligned with a perpendicular 45L passing through the center position 45C of the missing pattern portion 45. The independent thin line 60 may be arranged so as to be shifted from the missing pattern portion 45 in a certain direction in a parallel relationship as shown in FIG. 4A, or if the portions 47 and 52 are in a DC insulated state, the missing pattern portion may be used. 45 may be arranged.

独立細線６０は、導電細線１１が配置されていない欠落パターン部４５の面積のタッチパネル５０１全体の面積に対する比である面積率を補い、かつ回折を考慮して長さおよび設置位置を設定する。例えば欠落パターン部４５の長さＬ４５が１０μｍである場合、１１μｍ程度である長さＬ６０の独立細線６０を、欠落パターン部４５から欠落パターン部４５の長さＬ４５程度の距離Ｍ４５（１０μｍ程度）離して平行関係に配置する。 The independent thin line 60 compensates for the area ratio which is the ratio of the area of the missing pattern portion 45 where the conductive thin line 11 is not arranged to the entire area of the touch panel 501, and sets the length and the installation position in consideration of diffraction. For example, when the length L45 of the missing pattern portion 45 is 10 μm, the independent thin line 60 having a length L60 of about 11 μm is separated from the missing pattern portion 45 by a distance M45 (about 10 μm) of the length L45 of the missing pattern portion 45. In a parallel relationship.

欠落パターン部４５は長さＬ４５を有する。独立細線６０（１５）は長さＬ６０を有する。独立細線６０（１５）は、導電細線１１の縁端細線４３、５３の端４３Ｐ、５３Ｐから距離Ｍ４３、Ｍ５３だけ離れている。独立細線６０の中央位置６０Ｃは、欠落パターン部４５の中央位置４５Ｃを通る欠落パターン部４５の垂線４５Ｌ上に位置する。 The missing pattern portion 45 has a length L45. The independent thin line 60 (15) has a length L60. The independent thin wire 60 (15) is apart from the ends 43P, 53P of the edge thin wires 43, 53 of the conductive thin wire 11 by distances M43, M53. The central position 60C of the independent thin line 60 is located on a perpendicular 45L of the missing pattern portion 45 passing through the central position 45C of the missing pattern portion 45.

なお、分離部３０において、部分４７、５２の間の電気的な絶縁状態を確保するには、欠落パターン部４５は５μｍ以上の長さＬ４５を有することが望ましい。長さＬ４５は余裕を考慮して１０μｍ程度に設定することがより望ましい。独立細線６０は、導電細線１１の部分４７、５２すなわち端４３Ｐ、５３Ｐから５μｍ以上の距離Ｍ４３、Ｍ５３でそれぞれ離れた位置に配置すると望ましいが、１０μｍ程度の距離Ｍ４３、Ｍ５３でそれぞれ離れた位置に配置するとより望ましい。このように、方向Ｄ１１（図１Ｂ参照）から見て、距離Ｍ４３、Ｍ５３は欠落パターン部４５の長さＬ４５以下であることが望ましい。図４Ｂに示すように、基材部１０の表面１０Ａに溝１０Ｇを形成し、溝１０Ｇの内部に導電材料を入れて導電細線１１と独立細線１５とを形成する。溝１０Ｇに部分４７、５２と独立細線６０とが配置される。すなわち、上記三者をそれぞれ溝１０Ｇ内に配置する構成とすると、溝１０Ｇ同士の間に、基材部１０の表面１０Ａまでの仕切り部１０Ｈが基材部１０を形成する樹脂で形成されて配置されるので望ましい。 In the separating section 30, in order to ensure an electrical insulation state between the portions 47 and 52, the missing pattern section 45 desirably has a length L45 of 5 μm or more. More preferably, the length L45 is set to about 10 μm in consideration of a margin. It is desirable that the independent thin wire 60 be arranged at a distance of at least 5 μm from the portions 47 and 52 of the conductive thin wire 11, that is, the ends 43P and 53P at distances M43 and M53 of 5 μm or more. It is more desirable to arrange. Thus, when viewed from the direction D11 (see FIG. 1B), it is desirable that the distances M43 and M53 be equal to or less than the length L45 of the missing pattern portion 45. As shown in FIG. 4B, a groove 10G is formed on the surface 10A of the base member 10, and a conductive material is put in the groove 10G to form the conductive fine wires 11 and the independent fine wires 15. The portions 47 and 52 and the independent thin wires 60 are arranged in the groove 10G. In other words, if the three members are arranged in the grooves 10G, the partition 10H up to the surface 10A of the base 10 is formed of the resin forming the base 10 between the grooves 10G. Is desirable.

欠落パターン部４５から離れた位置に独立細線６０を配置する場合では、回折を考慮して、独立細線６０の長さＬ６０を欠落パターン部４５の長さＬ４５よりも若干長い寸法で設定すると望ましい。 In the case where the independent thin line 60 is arranged at a position distant from the missing pattern portion 45, it is desirable that the length L60 of the independent thin line 60 be set to be slightly longer than the length L45 of the missing pattern portion 45 in consideration of diffraction.

上述したように、分離部３０は、欠落パターン部４５と、欠落パターン部４５に応じて配置した独立細線６０を含む。この構成であれば、欠落パターン部４５毎に独立細線６０を対応して配置しているため、複数の欠落パターン部４５が直線状に配置されていても、タッチセンサ５０１の視認時に、直線的に並ぶ複数の欠落パターン部４５からなる縁端線３０Ａ、３０Ｂつまり分離部３０の視認が抑制される。なお、独立細線６０を欠落パターン部４５に対して同じ１つの方向Ｄ１０１に同じ距離Ｍ６０ずらして配置したことも分離部３０の視認状態の抑制に寄与する。 As described above, the separation unit 30 includes the missing pattern part 45 and the independent thin line 60 arranged according to the missing pattern part 45. With this configuration, since the independent thin lines 60 are arranged corresponding to each of the missing pattern portions 45, even when the plurality of missing pattern portions 45 are arranged in a straight line, when the touch sensor 501 is viewed, The visibility of the edge lines 30 A and 30 B composed of the plurality of missing pattern portions 45 arranged in a row, that is, the separation portion 30 is suppressed. It should be noted that the arrangement of the independent thin lines 60 shifted by the same distance M60 in the same one direction D101 with respect to the missing pattern portion 45 also contributes to the suppression of the visibility of the separation portion 30.

特許文献１に開示されている従来の静電容量式のタッチセンサでは、センサ電極がネット形状に配置された導電細線よりなる場合、センサ電極の外形形状を線状の分離部で画定する。分離部は、導電細線を部分的に欠落させた欠落パターン部が平面視で例えば直線状に配置されて構成される。直線状の分離部を設計することは容易であるが、この場合、分離部が視認され易くなり、表示装置の表示画面のタッチセンサを介しての視認性を損なう可能性がある。 In the conventional capacitive touch sensor disclosed in Patent Literature 1, when the sensor electrode is formed of conductive thin wires arranged in a net shape, the outer shape of the sensor electrode is defined by a linear separating portion. The separating portion is configured by arranging, for example, a linearly cut-out pattern portion in which conductive thin wires are partially deleted. Although it is easy to design a linear separating portion, in this case, the separating portion is easily viewed, and the visibility of the display screen of the display device via the touch sensor may be impaired.

実施の形態におけるタッチセンサ５０１では、平面視で欠落パターン部４５を直線的に並べて配置した縁端線３０Ａ、３０Ｂを含む分離部３０を有するが、独立細線６０を配置することで分離部３０の視認を抑制できる。このため、表示装置の表示画面の前方にタッチセンサ５０１を配置した場合、表示画面の視認性を損なう可能性も低減する。 The touch sensor 501 according to the embodiment includes the separation unit 30 including the edge lines 30A and 30B in which the missing pattern units 45 are linearly arranged in a plan view. Visual recognition can be suppressed. Therefore, when the touch sensor 501 is arranged in front of the display screen of the display device, the possibility that the visibility of the display screen is impaired is reduced.

なお、上記では直線状に欠落パターン部４５が配置されているが、分離部３０の縁端線３０Ａ、３０Ｂは平面視で直線のみに限定されることはなく、曲線であってもよい。 In the above description, the missing pattern portions 45 are linearly arranged, but the edge lines 30A and 30B of the separation portion 30 are not limited to only straight lines in plan view, and may be curved lines.

次に領域５０について説明する。領域５０ではダミーパターンが配置されている。ダミーパターンの基となるメッシュ５９は、領域４０と同じひし形状を有し、ダミーパターンは、上述した欠落パターン部４５および独立細線６０をひし形状の４つの辺５９Ａそれぞれの中央位置に位置する。 Next, the region 50 will be described. In the region 50, a dummy pattern is arranged. The mesh 59 serving as the base of the dummy pattern has the same rhombic shape as the region 40, and the dummy pattern is located at the center position of each of the four sides 59A of the rhombic shape with the above-described missing pattern portion 45 and the independent thin line 60.

The plurality of sides 39A of the plurality of meshes 39 include a plurality of missing pattern portions 45 which are straight lines connecting from the plurality of ends 43P of the plurality of edge thin lines 43 to the plurality of ends 53P of the plurality of edge thin lines 53, respectively. The side 39A of the corresponding mesh 39 among the plurality of sides 39A of the plurality of meshes 39 includes the corresponding missing pattern portion 45 of the plurality of missing pattern portions 45. The corresponding missing pattern portion 45 extends from the corresponding end 43P of the corresponding edge thin line 43 of the plurality of ends 43P of the plurality of edge thin lines 43 to the plurality of ends 53P of the plurality of edge thin lines 53.

図５Ａは図３に示すタッチセンサ５０１の拡大図であり、領域５０内の領域Ａ３を示す。図５Ｂは図５Ａに示すタッチセンサ５０１の拡大図である。図５Ａに示すように、領域５０において、ひし形状の一つの辺５９Ａは、導電細線よりなる２つの部分７１と欠落パターン部７３とを含む。欠落パターン部７３は辺５９Ａを構成する２つの部分７１の間の導電細線を分断した、もしくは導電細線を配置していない箇所である。欠落パターン部７３は辺５９Ａの中央位置に配置されているので、１つの辺５９Ａを構成する２つの部分７１同士は、ほぼ同じ長さを有する。 FIG. 5A is an enlarged view of the touch sensor 501 shown in FIG. FIG. 5B is an enlarged view of the touch sensor 501 shown in FIG. 5A. As shown in FIG. 5A, in the region 50, one side 59 A of the diamond shape includes two portions 71 made of conductive thin lines and a missing pattern portion 73. The missing pattern portion 73 is a portion where the conductive thin line between the two portions 71 constituting the side 59A is divided or the conductive thin line is not arranged. Since the missing pattern portion 73 is arranged at the center position of the side 59A, the two portions 71 forming one side 59A have substantially the same length.

領域５０において、複数の欠落パターン部７３が、方向Ｄ１０１に延びる直線上に並ぶように配置され、方向Ｄ１０１に直交する方向Ｄ１０２に延びる直線上に並ぶように配置されている。すなわち、複数の欠落パターン部７３は規則的な長方形の格子状のマトリクス形状に配置されている。これによって、領域５０では、メッシュ５９のひし形状の辺５９Ａの交点に繋がる４つの部分７１でそれぞれ構成される複数のＸ字形状を有するパターンが配置されている。換言すれば、領域５０には、１つのメッシュ５９のひし形状の全ての辺５９Ａに欠落パターン部７３を設けることで形成された複数のＸ字状パターンが規則的に配置されている。このように導電細線５１で閉塞される箇所を有しないパターンを規則的に配置した構成であれば、操作時等での領域５０内の静電容量の増加を低減でき、センサ電極２０の感度の向上が図りやすい。 In the region 50, the plurality of missing pattern portions 73 are arranged so as to be arranged on a straight line extending in the direction D101, and are arranged so as to be arranged on a straight line extending in a direction D102 orthogonal to the direction D101. That is, the plurality of missing pattern portions 73 are arranged in a regular rectangular lattice matrix. Thus, in the region 50, a plurality of X-shaped patterns each including four portions 71 connected to the intersection of the diamond-shaped sides 59A of the mesh 59 are arranged. In other words, in the region 50, a plurality of X-shaped patterns formed by providing the missing pattern portions 73 on all the rhombic sides 59A of one mesh 59 are regularly arranged. With such a configuration in which the pattern having no portion closed by the conductive thin wire 51 is regularly arranged, an increase in the capacitance in the region 50 during operation or the like can be reduced, and the sensitivity of the sensor electrode 20 can be reduced. It is easy to improve.

上述構成と同様に、直線形状の独立細線８０が欠落パターン部７３毎に対応して配置されている。簡単に説明すると、独立細線８０は、部分７１と同じ導電細線製で、辺５９Ａ内で対応する２つの部分７１から直流的に絶縁されて配置されている。図５Ａでは、直線形状の独立細線８０を、対応する欠落パターン部７３に近接した位置で、かつ平行関係に配置している。なお、独立細線８０は、独立細線６０と同様に、欠落パターン部７３の中央位置を通る垂線上に、長さ方向での中央位置を合わせて配置している。さらに、複数の独立細線８０が同じ方向に同じ寸法でずらした位置に配置している。なお、独立細線８０は、部分７１から直流的に絶縁されていれば、欠落パターン部７３上に配置されていてもよい。 As in the above-described configuration, linear independent thin lines 80 are arranged corresponding to each of the missing pattern portions 73. In brief, the independent thin wire 80 is made of the same conductive thin wire as the portion 71, and is arranged in a side 59A in a directionally insulated manner from the corresponding two portions 71. In FIG. 5A, linear independent thin lines 80 are arranged in a position close to the corresponding missing pattern portion 73 and in a parallel relationship. Like the independent thin line 60, the independent thin line 80 is arranged on a vertical line passing through the central position of the missing pattern portion 73 with the center position in the length direction aligned. Further, a plurality of independent fine wires 80 are arranged at positions shifted by the same dimension in the same direction. The independent thin wire 80 may be arranged on the missing pattern portion 73 as long as it is insulated from the portion 71 in a DC manner.

以上の説明のように、領域５０のダミーパターンは、部分７１を含むＸ字形状パターンと、欠落パターン部７３毎に対応して配置した独立細線８０とを含む。 As described above, the dummy pattern in the region 50 includes the X-shaped pattern including the portion 71 and the independent thin line 80 arranged corresponding to each of the missing pattern portions 73.

より具体的に説明すると、領域５０では、例えばメッシュ５９のひし形状の１つの辺５９Ａの中央位置に、長さＬ７３が１０μｍである欠落パターン部７３が設けられていろ、１１μｍの長さＬ８０を有する独立細線８０が欠落パターン部７３から紙面の右方向に１０μｍの距離だけ離して配置されている。つまり、領域５０は、分離部３０の視認状態と略同等な視認状態になるように、分離部３０と略同等の構成を有する。 More specifically, in the region 50, for example, a missing pattern portion 73 having a length L73 of 10 μm is provided at a center position of one side 59A of a diamond shape of the mesh 59, and a length L80 of 11 μm is set. Independent thin lines 80 are arranged at a distance of 10 μm to the right of the paper from the missing pattern portion 73. That is, the region 50 has a configuration substantially the same as that of the separation unit 30 so that the viewing state of the region 50 is approximately the same as that of the separation unit 30.

以上に説明したように、領域５０では、複数の欠落パターン部７３をマトリクス状に配置し、欠落パターン部７３毎に独立細線８０を対応させて配置している。このため、上述の分離線と同様に、複数の欠落パターン部７３が直線状で並ぶ配置であっても、それらを視認されることが抑制できる。このため、タッチセンサ５０１を表示装置の表示画面の前方に配置した場合、表示画面の視認性を損なう可能性も低減する。 As described above, in the region 50, the plurality of missing pattern portions 73 are arranged in a matrix, and the independent thin lines 80 are arranged corresponding to each of the missing pattern portions 73. Therefore, similarly to the above-described separation line, even if the plurality of missing pattern portions 73 are arranged in a straight line, they can be suppressed from being visually recognized. Therefore, when the touch sensor 501 is arranged in front of the display screen of the display device, the possibility that the visibility of the display screen is impaired is reduced.

なお、上記では、領域５０のダミーパターンとして、欠落パターン部７３をマトリクス状に配置することで得られるＸ字状パターンと、欠落パターン部７３に対応して配置した独立細線８０とを含む。欠落パターン部７３の配置状態によってＸ字状パターンは異なる外形を有する場合がある。この場合においても、ダミーパターンが欠落パターン部７３毎に配置した独立細線８０を含むことで、複数の欠落パターン部７３が直線状で並んでいても、それらを視認されることが抑制できる。 In the above description, the dummy pattern of the region 50 includes the X-shaped pattern obtained by arranging the missing pattern portions 73 in a matrix, and the independent thin lines 80 arranged corresponding to the missing pattern portions 73. The X-shaped pattern may have a different outer shape depending on the arrangement state of the missing pattern portion 73. Also in this case, since the dummy patterns include the independent thin lines 80 arranged for each of the missing pattern portions 73, even if the plurality of missing pattern portions 73 are arranged in a straight line, they can be suppressed from being visually recognized.

なお、部分７１と独立細線８０は、上述した分離部３０の場合と同様に、基材部１０の表面１０Ａに形成した溝１０Ｇ内に配置した構成にすると望ましい。 It is desirable that the portion 71 and the independent thin line 80 be arranged in the groove 10G formed in the surface 10A of the base member 10 as in the case of the separation portion 30 described above.

複数の独立細線１５は、配置面１０Ｐに直角の方向Ｄ１１から見て、領域５０に位置する複数の独立細線８０をさらに含む。複数の導電細線５１は、複数のメッシュ５９の複数の辺５９Ａ上に位置する複数の端７４Ｐをそれぞれ有する複数の導電細線７４と、複数のメッシュ５９の複数の辺５９Ａ上に位置する複数の端７５Ｐをそれぞれ有する複数の導電細線７５とを含む。複数の導電細線７４のうちの、複数の独立細線８０のそれぞれの独立細線８０に対応する導電細線７４と、複数の導電細線７５のうちの上記それぞれの独立細線８０に対応する導電細線７５は、複数のメッシュ５９のうちの対応するメッシュ５９を画定する。複数のメッシュ５９の複数の辺５９Ａは、複数の導電細線７４の複数の端７４Ｐから複数の導電細線７５の複数の端７５Ｐまでそれぞれ結ぶ直線である複数の欠落パターン部７３を含む。複数のメッシュ５９の複数の辺５９Ａのうちの上記対応するメッシュ５９の辺５９Ａは、複数の欠落パターン部７３のうちの対応する欠落パターン部７３を含む。上記対応する欠落パターン部７３は、複数の導電細線７４の複数の端７４Ｐのうちの上記対応する導電細線７４の対応する端７４Ｐから複数の導電細線７５の複数の端７５Ｐのうちの上記対応する導電細線７５の対応する端７５Ｐまで結ぶ。上記それぞれの独立細線８０は、上記対応する欠落パターン部７３の近接した位置に配置されている。上記それぞれの独立細線８０は、複数の欠落パターン部７３のうちの上記対応する欠落パターン部７３の最も近くに配置されている。また、上記それぞれの独立細線８０は、複数の導電細線１１のうちの上記対応する導電細線７４、７５のうちの一方に最も近く配置され他方に２番目に近く配置されている。 The plurality of independent fine lines 15 further include a plurality of independent fine lines 80 located in the region 50 when viewed from the direction D11 perpendicular to the arrangement surface 10P. The plurality of conductive thin lines 51 include a plurality of conductive thin lines 74 each having a plurality of ends 74P located on a plurality of sides 59A of a plurality of meshes 59, and a plurality of ends located on a plurality of sides 59A of a plurality of meshes 59. 75P, and a plurality of conductive thin wires 75 each having 75P. Of the plurality of conductive thin wires 74, the conductive thin wire 74 corresponding to each of the independent thin wires 80 of the plurality of independent thin wires 80, and the conductive thin wire 75 corresponding to the respective independent thin wires 80 of the plurality of conductive thin wires 75, A corresponding mesh 59 of the plurality of meshes 59 is defined. The plurality of sides 59A of the plurality of meshes 59 include a plurality of missing pattern portions 73 which are straight lines connecting from the plurality of ends 74P of the plurality of conductive thin lines 74 to the plurality of ends 75P of the plurality of conductive thin lines 75, respectively. The side 59A of the corresponding mesh 59 among the plurality of sides 59A of the plurality of meshes 59 includes the corresponding missing pattern portion 73 of the plurality of missing pattern portions 73. The corresponding missing pattern portion 73 corresponds to the corresponding one of the plurality of ends 75P of the plurality of conductive thin lines 75 from the corresponding end 74P of the corresponding conductive thin line 74 among the plurality of ends 74P of the plurality of conductive thin lines 74. It connects to the corresponding end 75P of the conductive thin wire 75. The respective independent thin lines 80 are arranged at positions adjacent to the corresponding missing pattern portions 73. Each of the independent thin lines 80 is arranged closest to the corresponding one of the plurality of missing pattern portions 73. Further, each of the independent thin wires 80 is arranged closest to one of the corresponding conductive thin wires 74 and 75 of the plurality of conductive thin wires 11, and is arranged second closest to the other.

上記それぞれの独立細線８０は上記対応する欠落パターン部７３に近接して上記対応する欠落パターン部７３に平行に延びる。 Each of the independent fine lines 80 extends parallel to and in close proximity to the corresponding missing pattern portion 73.

上記対応するメッシュ５９の辺５９Ａと上記それぞれの独立細線８０とは直線状に延びている。 The corresponding side 59A of the mesh 59 and each of the independent thin lines 80 extend linearly.

上記それぞれの独立細線８０の中央位置８０Ｃは、上記対応する欠落パターン部７３の中央位置７３Ｃを通る上記対応する欠落パターン部７３の垂線７３Ｌ上に位置する。 The central position 80C of each of the independent thin lines 80 is located on the perpendicular 73L of the corresponding missing pattern portion 73 passing through the central position 73C of the corresponding missing pattern portion 73.

上記それぞれの独立細線８０は上記対応する欠落パターン部７３よりも長い。 Each of the independent thin lines 80 is longer than the corresponding missing pattern portion 73.

上記それぞれの独立細線８０は上記対応する欠落パターン部７３に対して１つの方向Ｄ１０１に位置する。 Each of the independent thin lines 80 is located in one direction D101 with respect to the corresponding missing pattern portion 73.

独立細線８０は、導電細線７４、７５から直流的に絶縁される位置に配置されている。すなわち、独立細線８０は、欠落パターン部７３を設けた辺の対となる導電細線７４、７５の間の直線からなる欠落パターン部７３に対して、近接する位置に平行関係で横にずらした位置に配置されている。独立細線８０は、欠落パターン部７３の中央位置７３Ｃを通る垂線７３Ｌ上に、独立細線８０の長さ方向での中央位置８０Ｃを合わせて配置することが望ましい。なお、独立細線８０は、図５Ａに示したように欠落パターン部７３から一定方向に平行関係でずらして配置してもよいし、導電細線７４、７５から直流的に絶縁状態であれば欠落パターン部７３上に配置されていてもよい。 The independent thin wire 80 is arranged at a position insulated from the conductive thin wires 74 and 75 in a DC manner. In other words, the independent fine line 80 is shifted laterally in a parallel relationship to a position close to the missing pattern portion 73 formed of a straight line between the conductive thin lines 74 and 75 forming a pair of sides on which the missing pattern portion 73 is provided. Are located in It is desirable that the independent thin line 80 is arranged so that the central position 80C in the longitudinal direction of the independent thin line 80 is aligned with a vertical line 73L passing through the central position 73C of the missing pattern portion 73. The independent thin wire 80 may be arranged so as to be shifted from the missing pattern portion 73 in a certain direction in a parallel relationship as shown in FIG. 5A, or may be omitted if the conductive thin wires 74 and 75 are in a DC insulated state. It may be arranged on the part 73.

独立細線８０は、導電細線１１が配置されていない欠落パターン部７３の面積のタッチパネル５０１全体の面積に対する比である面積率を補い、かつ回折を考慮して長さおよび設置位置を設定する。例えば欠落パターン部７３の長さＬ７３が１０μｍである場合、１１μｍ程度である長さＬ８０の独立細線８０を、欠落パターン部７３から欠落パターン部７３の長さＬ７３程度の距離Ｍ７３（１０μｍ程度）離して平行関係に配置する。 The independent thin line 80 compensates for the area ratio which is the ratio of the area of the missing pattern portion 73 where the conductive thin line 11 is not arranged to the entire area of the touch panel 501, and sets the length and the installation position in consideration of diffraction. For example, when the length L73 of the missing pattern portion 73 is 10 μm, the independent thin line 80 having a length L80 of about 11 μm is separated from the missing pattern portion 73 by a distance M73 (about 10 μm) of the length L73 of the missing pattern portion 73. In a parallel relationship.

欠落パターン部７３は長さＬ７３を有する。独立細線８０（１５）は長さＬ８０を有する。独立細線８０（１５）は、導電細線７４、７５の端７４Ｐ、７５Ｐから距離Ｍ７４、Ｍ７５だけそれぞれ離れている。独立細線８０の中央位置８０Ｃは、欠落パターン部７３の中央位置７３Ｃを通る欠落パターン部７３の垂線７３Ｌ上に位置する。 The missing pattern portion 73 has a length L73. The independent thin line 80 (15) has a length L80. The independent thin wire 80 (15) is apart from the ends 74P, 75P of the conductive thin wires 74, 75 by distances M74, M75, respectively. The center position 80C of the independent thin line 80 is located on a vertical line 73L of the missing pattern portion 73 passing through the central position 73C of the missing pattern portion 73.

なお、導電細線７４、７５の間の電気的な絶縁状態を確保するには、欠落パターン部７３は５μｍ以上の長さＬ７３を有することが望ましい。長さＬ７３は余裕を考慮して１０μｍ程度に設定することがより望ましい。独立細線８０は、導電細線７４、７５の端７４Ｐ、７５Ｐから５μｍ以上の距離Ｍ７４、Ｍ７５でそれぞれ離れた位置に配置すると望ましいが、１０μｍ程度の距離Ｍ７４、Ｍ７５でそれぞれ離れた位置に配置するとより望ましい。このように、方向Ｄ１１（図１Ｂ参照）から見て、距離Ｍ７４、Ｍ７５は欠落パターン部７３の長さＬ７３以下であることが望ましい。なお、さらに望ましくは、図４Ｂに示すように、基材部１０の表面１０Ａに溝１０Ｇを形成し、溝１０Ｇの内部に導電細線７４、７５と独立細線８０とを配置する構成とする。すなわち、上記三者をそれぞれ溝１０Ｇ内に配置する構成とすると、溝１０Ｇ同士の間に、基材部１０の表面までの仕切り部１０Ｈが基材部１０を形成する樹脂で形成されて配置されるので望ましい。 In order to ensure an electrical insulation state between the conductive fine wires 74 and 75, the missing pattern portion 73 preferably has a length L73 of 5 μm or more. More preferably, the length L73 is set to about 10 μm in consideration of a margin. It is desirable that the independent thin wire 80 is arranged at a distance of at least 5 μm from the ends 74P, 75P of the conductive thin wires 74, 75 at a distance M74, M75, but it is more desirable to arrange the independent thin wire at a distance M74, M75 of about 10 μm. desirable. Thus, when viewed from the direction D11 (see FIG. 1B), it is desirable that the distances M74 and M75 be equal to or less than the length L73 of the missing pattern portion 73. More preferably, as shown in FIG. 4B, a groove 10G is formed on the surface 10A of the base member 10, and the conductive fine wires 74 and 75 and the independent fine wire 80 are arranged inside the groove 10G.

独立細線８５は、縁端細線９３、１１３から直流的に絶縁される位置に配置されている。すなわち、独立細線８５は、欠落パターン部１１５を設けた辺の対となる縁端細線９３、１１３の間の直線からなる欠落パターン部１１５に対して、近接する位置に平行関係で横にずらした位置に配置されている。独立細線８５は、欠落パターン部１１５の中央位置１１５Ｃを通る垂線１１５Ｌ上に、独立細線８５の長さ方向での中央位置８５Ｃを合わせて配置することが望ましい。なお、独立細線８５は、図６Ａに示したように欠落パターン部１１５から一定方向に平行関係でずらして配置してもよいし、縁端細線９３、１１３から直流的に絶縁状態であれば欠落パターン部１１５上に配置されていてもよい。 The independent thin wire 85 is arranged at a position insulated from the edge thin wires 93 and 113 in a DC manner.

なお、分離部１００において、縁端細線９３、１１３の間の電気的な絶縁状態を確保するには、欠落パターン部１１５は５μｍ以上の長さＬ１１５を有することが望ましい。長さＬ１１５は余裕を考慮して１０μｍ程度に設定することがより望ましい。独立細線８５は、導電細線１１の縁端細線９３、１１３の端９３Ｐ、１１３Ｐから５μｍ以上の距離Ｍ９３、Ｍ１１３でそれぞれ離れた位置に配置すると望ましいが、１０μｍ程度の距離Ｍ９３、Ｍ１１３でそれぞれ離れた位置に配置するとより望ましい。このように、方向Ｄ１１（図１Ｂ参照）から見て、距離Ｍ９３、Ｍ１１３は欠落パターン部１１５の長さＬ１１５以下であることが望ましい。なお、さらに望ましくは、図４Ｂに示すように、基材部１０の表面１０Ａに溝を形成し、溝１０Ａの内部に縁端細線９３、１１３と独立細線８５とを配置する構成とする。すなわち、上記三者をそれぞれ溝１０Ｇ内に配置する構成とすると、溝１０Ｇ同士の間に、基材部１０の表面１０Ａまでの仕切り部１０Ｈが基材部１０を形成する樹脂で形成されて配置されるので望ましい。 In the separating section 100, in order to ensure an electrical insulation state between the thin edge lines 93 and 113, the missing pattern section 115 preferably has a length L115 of 5 μm or more. More preferably, the length L115 is set to about 10 μm in consideration of a margin.

It is more desirable to arrange them at positions. Thus, when viewed from the direction D11 (see FIG. 1B), it is desirable that the distances M93 and M113 be equal to or less than the length L115 of the missing pattern portion 115. More preferably, as shown in FIG. 4B, a groove is formed on the surface 10A of the base member 10 and the edge thin lines 93 and 113 and the independent thin line 85 are arranged inside the groove 10A. That is, if the above-mentioned three members are arranged in the grooves 10G, the partition 10H up to the surface 10A of the base 10 is formed of the resin forming the base 10 between the grooves 10G. Is desirable.

欠落パターン部１１５から離れた位置に独立細線８５を配置する場合では、回折を考慮して、独立細線８５の長さＬ８５を欠落パターン部１１５の長さＬ１１５よりも若干長い寸法で設定すると望ましい。 In the case where the independent thin line 85 is arranged at a position distant from the missing pattern portion 115, it is desirable that the length L85 of the independent thin line 85 be set slightly longer than the length L115 of the missing pattern portion 115 in consideration of diffraction.

That is, the respective independent thin lines 15 are arranged at the same distance M115 in the opposite direction of the same one direction D11 with respect to the corresponding missing pattern portion 45.
