Abstract

A display device includes: a substrate having a first display area, a second display area, and a non-display area; a first circuit disposed on the substrate; a first light emitter electrically connected to the first circuit and which overlaps the first display area; a second circuit disposed on the substrate; a second light emitter electrically connected to the second circuit and which overlaps the second display area; and a scan driver positioned on the substrate and which overlaps at least a portion of the second display area and the non-display area.
