Abstract: A display device including a substrate and a stacked structure on the substrate. The substrate has a first hole, and the stacked structure has a second hole. The second hole partially overlaps the first hole and has an edge outside the first hole in a plan view. The substrate has a substrate exposed portion exposed to the second hole, and the substrate exposed portion is partially depressed in an edge direction of the second hole.
