1. A display device comprising:
a substrate having a first hole; and
a stacked structure on the substrate, the stacked structure having a second hole and an edge outside the first hole in a cross-sectional view,
wherein the first hole partially overlaps the second hole,
wherein the substrate has a substrate exposed portion exposed to the second hole, and
wherein the substrate exposed portion is partially depressed in an edge direction of the second hole,
wherein the substrate exposed portion has a first portion having a first distance from a side surface of the substrate exposed portion defining the first hole to a side surface of the stacked structure defining the second hole in a plan view and a second portion having a second distance from the side surface of the substrate exposed portion to the side surface of the stacked structure in the plan view, and
wherein the second distance is smaller than the first distance.
