1. A transparent display device with a touch sensor, the transparent display device comprising:
a substrate;
a plurality of transmissive areas and a non-transmissive area disposed between transmissive areas adjacent to each other on the substrate;
a plurality of touch sensors respectively provided in the plurality of transmissive areas on the substrate, each touch sensor including a touch sensor electrode;
a plurality of pixels disposed in the non-transmissive area on the substrate, each pixel including an anode electrode, a light emitting layer, and a cathode electrode;
a touch line extended in the non-transmissive area in a first direction and electrically connected to the touch sensor electrode; and
a common power line electrically connected to the cathode electrode to supply a cathode power source,
wherein the non-transmissive area includes a cathode power area to which the cathode power source is applied through the common power line,
wherein the cathode power area includes a first cathode power area disposed between the touch sensors adjacent to each other in a second direction and a second cathode power area disposed between the touch sensors adjacent to each other in the first direction, and
wherein the second cathode power area has resistance higher than that of the first cathode power area.
