Abstract
A display device includes a display panel and an optical member. The display panel includes a lower substrate and an upper substrate. The display panel forms a light-transmitting area and a display area near the light-transmitting area. The optical member is adjacent to a rear surface of the display panel and overlaps with a portion corresponding to the light-transmitting area. The display area includes a thin film transistor and an organic light emitting element configured to receive a current from the thin film transistor. The light-transmitting area does not include a metal layer, which is disposed in the display area. The upper substrate and the lower substrate do not have a through-hole structure in the light-transmitting area.
