A display device includes a substrate having an insulating surface, a pixel part having a plurality of pixels on the insulating surface, a terminal part including a first terminal arranged in a region outside the pixel part on the insulating surface, and a second terminal arranged in a region inside the first terminal, a wiring part including a first wiring arranged between the pixel part and the terminal part, a sensing part overlapped on the pixel part, and a sealing part covering the pixel part and the wiring part. The first wiring included in the wiring part is electrically connected to a first detection electrode at an opening provided in the second inorganic insulating layer, and the first wiring extends to an outer region of the second inorganic insulating layer and is electrically connected to the second terminal.
