Abstract: A display device includes a resin substrate including a through hole in a terminal area around a display area in which an image is displayed, a circuit layer including a thin film transistor and disposed in the display area on the resin substrate, a wire extending from the circuit layer and formed inside of the through hole, and an IC driver disposed on a side of the resin substrate opposite to a side on which the circuit layer is disposed. The IC driver includes a terminal that protrudes into the through hole and is in contact with the wire formed inside of the through hole such that the IC driver and the circuit layer are electrically connected to each other.

Abstract: A display device includes a resin layer having a first surface and second surface; an inorganic layer laminated on and in contact with the first surface; and a circuit layer on the inorganic layer, having a circuit to display images on a display area, and having a peripheral area outside the display area. The resin layer, the inorganic layer, and the circuit layer curve with the resin layer inside. The resin layer on the first surface has a recess extending to both ends, in a development view. The inorganic layer has a curved portion to be convex along a surface of the recess and in a depth direction of the recess, in a development view. The resin layer at the recess curves with the first surface outside. The inorganic layer at the curved portion curves with a concave surface of the curved portion outside.
