Claim 9:
10. A transparent display device comprising:
a substrate provided with a plurality of transmissive areas 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 light emitting elements respectively provided in the plurality of light emission areas over the substrate, and including an anode electrode, a light emitting layer, and a cathode electrode;
a plurality of driving transistors electrically connected to the anode electrode of each of the light emitting elements, including an active layer, a gate electrode, a source electrode, and a drain electrode;
a plurality of touch sensors respectively provided in the plurality of transmissive areas over the substrate, and including a touch sensor electrode provided in a same layer as the cathode electrode;
a plurality of touch bridge lines provided in the non-transmissive area;
a plurality of touch connection portions electrically connecting the plurality of touch bridge lines with the plurality of touch sensors, including a touch contact electrode provided in the transmissive area and a touch connection line formed in a layer provided between the substrate and the driving transistor;
a first undercut structure provided in the transmissive area, having a planar closed shape,
wherein the cathode electrode and the touch sensor electrode are separated from each other by the first undercut structure.
