Claim 0:
1. A transparent display device comprising:
a substrate provided with a plurality of transmissive areas through which externally incident light passes and a non-transmissive area disposed between the transmissive areas adjacent to each other, the non-transmissive area including a plurality of light emission areas;
a plurality of touch sensors respectively provided in the plurality of transmissive areas over the substrate, including a touch sensor electrode;
a plurality of touch lines provided in the non-transmissive area over the substrate and extended in a first direction;
a plurality of touch bridge lines provided in the non-transmissive area over the substrate and extended in a second direction to be electrically connected to one of the plurality of touch lines;
a plurality of touch connection portions electrically connecting the plurality of touch bridge lines with the plurality of touch sensors, the plurality of touch connection portions including a high resistance line;
a plurality of light emitting elements respectively provided in the plurality of light emission areas over the substrate, including an anode electrode, a light emitting layer, and a cathode electrode; and
a first undercut structure provided along an edge of the transmissive area,
wherein the cathode electrode of the light emitting element is disposed in a same layer as the touch sensor electrode of the touch sensor, and
wherein the cathode electrode and the touch sensor electrode are separated from each other by the first undercut structure.
