A display device includes a panel member, a flexible substrate, and a tap. The flexible substrate includes a substrate body and a substrate extending portion. The substrate body is disposed in an area of a surface of the panel member inner than an outer peripheral edge portion of the surface. The substrate extension portion is extended from an outer peripheral edge portion of the substrate body. The substrate extension portion includes an overlapping portion overlapping a section of the outer peripheral edge portion of the surface. The tape is pasted to the area inner than the outer peripheral edge portion of the surface. The tape covers the substrate extension portion that is folded back to the substrate body from an opposite side from the substrate body such that the overlapping portion does not overlap the outer peripheral edge portion of the surface to hold the substrate extension portion.
