Abstract

[Object] To provide an input device, a display device, and a mobile terminal which can reduce a possibility that at least a connection portion in detection wiring may be viewed by a user while making the thickness of a light shielding layer relatively small.

[Solution] An input device X1 includes a base 2 which includes a first main face 2a and a second main face 2b located on a side opposite to the first main face 2a; a first detection electrode pattern 3 on the second main face 2b of the base 2; detection wiring 8 on the second main face 2b of the base 2 and including a connection portion 8a connected to the first detection electrode pattern 3; a first light shielding layer 6 on the first main face 2a or the second main face 2b of the base 2, and located on the first main face 2a side of the base 2 as compared to the detection wiring 8; and a second light shielding layer 11 on the first main face 2a or the second main face 2b of the base 2, in which the first light shielding layer 6 has a first region which overlaps with the second light shielding layer 11 in plan view, and at least the connection portion 8a in the detection wiring 8 is located by being overlapped with the first region in plan view.

Claims

1. An input device comprising:

a base having a first face and a second face opposite the first face, the base comprising;

an input region having a first pair of opposing sides and a second pair of opposing sides perpendicular to the first pair of opposing sides; and

a non-input region surrounding the input region;

a detection electrode pattern disposed on the second face at the input region;

a first insulating layer disposed on and below the second face;

detection wiring, disposed on and below the first insulating layer, and including connection portions, base portions, and lead out portions, wherein the base portions and the connection portions extend from the detection electrode pattern, in a first direction along one of the first pair of opposing sides and a second direction along one of the second pair of opposing sides, to the lead-out portions;

a first light shielding layer disposed on and below the second face of the base and above the detection wiring;

a second insulating layer disposed on and below the first insulating layer and at least on the connection portions in the detection wiring;

a second light shielding layer disposed below and on the second insulating layer, wherein

the first light shielding layer overlaps the second light shielding layer in a plan view, and

the connection portions and the base portions of the detection wiring are located between the first light shielding layer and the second light shielding layer and the base portions are overlapped by the first light shielding layer and the second light shielding layer within the non-input region in the plan view and most of the connection portions are overlapped by the first light shielding layer and the second light shielding layer within the non-input region in the plan view.

2. The input device according to claim 1, wherein

the detection electrode pattern is located in the input region,

the detection wiring, the second insulating layer, the first light shielding layer, and the second light shielding layer are located in the non-input region, and

the second light shielding layer covers a first end portion of the second insulating layer located closer to the input region.

3. The input device according to claim 1, wherein

the detection electrode pattern is located in the input region,

the detection wiring, the second insulating layer, the first light shielding layer, and the second light shielding layer are located in a the non-input region, and

the second light shielding layer covers a second end portion of the second insulating layer located far away from the input region.

4. The input device according to claim 3, wherein

the base has an end face located between the first face and the second face, and

the second insulating layer covers at least a part of the end face.

5. The input device according to claim 1, wherein the second light shielding layer is conductive.

6. The input device according to claim 1, wherein

the connection portions are located closer to the input region than the base portions and the lead-out portions.

7. The input device according to claim 1, further comprising:

a decorating layer on the first face of the base, wherein

at least the connection portions are located in a region which overlaps with the decorating layer in the plan view.

8. The input device according to claim 1, wherein

the base is formed of glass, and

the first light shielding layer is formed of a resin.

9. The input device according to claim 1, wherein

the first light shielding layer and the second light shielding layer have approximately the same shape in the plan view.

10. A display device comprising:

the input device according to claim 1;

a display panel arranged so as to face the input device; and

a housing which accommodates the display panel.

11. An electronic apparatus comprising:

the display device according to claim 10.
