Abstract: A display device is disclosed that includes a substrate, a display portion, a conductive layer, an inorganic layer, and an amorphous silicon layer. The substrate includes a first area including a transmission area and a non-transmission area adjacent to the transmission area, and a second area adjacent to the first area. The display portion is disposed in the non-transmission area and the second area on the substrate. The conductive layer is disposed between the substrate and the display portion, and overlaps the non-transmission area and the second area. The inorganic layer is disposed on the substrate under the conductive layer, in contact with the conductive layer, and overlaps the conductive layer. The amorphous silicon layer is disposed on the substrate, under the inorganic layer, in contact with the inorganic layer, overlaps the conductive layer in the first area, and entirely overlaps the substrate in the second area.

Abstract: A display device includes a substrate, a butter layer and light emitting diodes. The substrate defines a first display area including a first pixel area and a transmission area and a second display area including a second pixel area and surrounding at least a portion of the first display area, and the substrate includes an adhesive layer through which a first opening overlapping the transmission area is defined. The buffer layer is disposed on the substrate, and a second opening overlapping the transmission area is defined through the buffer layer. The light emitting diodes are disposed on the buffer layer and overlap the first and second pixel areas.
