Abstract: A transparent display device may include a substrate, a transmissive area, a non-transmissive area, and a plurality of subpixels provided in the non-transmissive area, having a light emitting element, which may include an anode electrode, a light emitting layer and a cathode electrode. The transparent display device may further include a touch sensor disposed in the transmissive area, including a touch sensor electrode, and a sensing transistor for sensing a voltage of the touch sensor. The cathode electrode of the light emitting element and the touch sensor electrode of the touch sensor may be provided on a same layer and may be separated by a first undercut structure. The cathode electrode may extend to the transmissive area such that the cathode electrode is located in the transmissive area and in the non-transmissive area. The sensing transistor may be disposed to overlap the cathode electrode located in the transmissive area.
