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.
