Abstract: A display device in which a signal transmission region, a peripheral region surrounding at least a portion of the signal transmission region, and a display region adjacent to the peripheral region are defined includes a base layer, a circuit layer disposed on the base layer, and a light-emitting element layer disposed on the circuit layer. The light-emitting element layer includes a plurality of light-emitting elements disposed in the display region, and a pixel defining film in which a plurality of light-emitting openings in which the plurality of light-emitting elements is disposed respectively is defined. A hole penetrating each of the circuit layer and the light-emitting element layer is defined in the signal transmission region, a portion of the pixel defining film is disposed in the peripheral region, and a first opening defined in the peripheral region is defined in the portion, disposed in the peripheral region, of the pixel defining film.
