Abstract: A display device includes a substrate including a display area in which emission areas are arranged, a non-display area, a hole area, and a hole peripheral area. A light emitting element layer includes light emitting elements respectively corresponding to the emission areas. A through hole is disposed on the hole area and passes through at least the substrate. Sealing auxiliary units are disposed in the hole peripheral area and sequentially surround an edge of the hole area. A circuit layer includes pixel drivers corresponding to the emission areas. Data lines transmit data signals to the pixel drivers. Each of hole intersection data lines crossing the hole area and the hole peripheral area, among the data lines, include a hole bypass unit disposed in the hole peripheral area. The hole bypass units of the hole intersection data lines overlap the sealing auxiliary units.
