Abstract: A display device and a method of manufacturing the same are provided. The display device comprises a substrate comprising a display area in which emission areas are arranged, a main non-display area around the display area, a hole area surrounded by the display area, and an additional non-display area between the hole area and the display area; a circuit layer; a light emitting element layer; a sealing layer; a through portion in the hole area and penetrating at least the substrate; and sealing auxiliary structures in the additional non-display area and sequentially surrounding the hole area. Each of the sealing auxiliary structures comprises a first undercut portion in which a first cover layer protrudes from a first main layer; and a second undercut portion in which a second cover layer protrudes from a second main layer.
