Abstract: A display device includes (i) a substrate having a first area, a second area, and a bending area located between the first area and the second area, where the substrate is bent along a bending axis in the bending area, the substrate includes a thin portion at an edge portion of the bending area, and the thin portion extends from the second area to the first area and has a thickness less than a thickness of the substrate at a center of the bending area; and (ii) an inorganic insulating layer over the substrate, where the inorganic insulating layer exposes the thin portion in the bending area.
