1. A transparent display device comprising:
a substrate including a transmissive area and a non-transmissive area;
a touch line on the substrate in the non-transmissive area;
a touch bridge line in the non-transmissive area;
a touch contact electrode electrically connected to the touch bridge line;
a touch sensor in the transmissive area and including a touch sensor electrode overlapping with the touch contact electrode; and
a cathode electrode disposed on the substrate,
wherein the touch sensor contacts the touch contact electrode so the touch sensor is electrically connected to the touch bridge line,
wherein the cathode electrode is separated from the touch sensor via an undercut area, and
wherein the cathode electrode and the touch sensor comprise a same material and are formed on a same layer.
