Abstract

A peripheral wiring region of a display device includes a first insulating layer on a substrate, a first wiring layer on the first insulating layer, a second insulating layer which is present on the first insulating layer and covers the first wiring layer, and a second wiring layer on the second insulating layer. A plurality of video signal wirings are arranged in the first wiring layer. A plurality of touch detection wirings arranged in a matrix in an X direction and a Y direction and a conductor pattern to which a fixed potential is supplied are formed in the second wiring layer. The conductor pattern is arranged at a position overlapping a part of the plurality of video signal wirings and is capacitively coupled to the part of the plurality of video signal wirings.
