Abstract: A display device includes a display panel including a first display area including first pixels, and a second display area including a pixel portion, in which second pixels are disposed, and a transmission portion through which light is transmitted. The pixel portion of the second display area includes a base member, a metal layer disposed on the base member to define the transmission portion, a first active layer disposed on the metal layer and including a first material, and a first gate layer disposed on the first active layer. A hole is defined through the metal layer to overlap at least a part of the first active layer in a thickness direction.
