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.

Abstract: A display device may include a substrate, a display element, and an organic insulating layer. The substrate may include a first area, a second area, and a bent area. The bent area may be connected between the first area and the second area, may be bent according to a bending axis, and may be narrower than the first area in a direction parallel to the bending axis. The display element may overlap the substrate. The organic insulating layer may be spaced from the display element, may be arranged at an edge of the substrate, and may only partially overlap a first face of the substrate. A face of the organic insulating layer may be coplanar with a second face of the substrate.
