Abstract: A display device comprises a substrate including a plurality of pixel areas that are spaced apart from each other and a plurality of transmissive areas between the plurality of pixel areas, wherein each of the plurality of pixel areas includes a plurality of sub pixels; and a plurality of signal lines that extend in a first direction on the substrate, wherein the plurality of sub pixels include a plurality of pixel circuits, wherein the plurality of signal lines overlap the plurality of pixel circuits without the plurality of signal lines overlapping the plurality of transmissive areas. Accordingly, the plurality of pixel areas and the plurality of signal lines are in the same area to reduce the size of the opaque area in the entire display device and enlarge a size of the transmissive area to implement a transparent display device.
