Abstract: A transparent display device is disclosed, which may have high light transmittance in a non-display area as well as a display area, and may increase or maximize a light emission area in a non-transmissive area. The transparent display device comprises a substrate provided with a display area, in which a plurality of subpixels are disposed, and a non-display area adjacent to the display area, anode electrodes provided in each of the plurality of subpixels over the substrate, a light emitting layer provided over the anode electrodes, a cathode electrode provided over the light emitting layer, a pixel power line provided over the substrate and extended in the display area in a first direction, and a common power line provided over the substrate and extended in the display area in the first direction. The display area includes a non-transmissive area provided with the common power line and the pixel power line, and a transmissive area provided between the common power line and the pixel power line.

Abstract: A transparent display device is disclosed, which may improve light transmittance in a transmissive area and increase or maximize a light emission area in a non-transmissive area. The transparent display device includes a substrate provided with a display area including a transmissive area and a non-transmissive area, in which a plurality of subpixels are disposed, and a non-display area surrounding the display area, at least one insulating film provided over the substrate, anode electrodes provided in each of the plurality of subpixels over the at least one insulating film, a bank provided among the anode electrodes, a light emitting layer provided over the anode electrodes, and a cathode electrode provided over the light emitting layer. The at least one insulating film and the bank are provided in only the non-transmissive area.
