Abstract: A display device includes a first pixel and a second pixel. A light emitting element and a pixel circuit of the second pixel are in a second area. The first pixel includes a silicon transistor and an oxide transistor in the second area. The first pixel includes a connection line that electrically connects one of the silicon transistor and the oxide transistor to a light emitting element in a first area. The connection line is on the same layer as the oxide semiconductor pattern and includes a transparent conductive oxide.

Abstract: A display panel includes: a base layer; a plurality of light emitting elements arranged on the base layer; a partition wall that is disposed between the light emitting elements and electrically connects electrodes of the light emitting elements; and a plurality of inorganic patterns arranged on the light emitting elements. A recessed part recessed in a direction to the base layer is defined in the partition wall, and each of the plurality of inorganic patterns is disposed on the partition wall and covers one side surface of the partition wall that defines the recessed part.

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.
