1. A transparent touch display device, comprising:
a substrate including a pixel area, a first transmissive area positioned on a first side of the pixel area, and a second transmissive area positioned on a second side of the pixel area;
a driving transistor disposed in the pixel area;
an anode electrode disposed in the pixel area, positioned on the driving transistor, and electrically connected with a source electrode or drain electrode of the driving transistor;
a light emitting layer positioned on the anode electrode;
a display cathode electrode positioned on the light emitting layer;
a first touch cathode electrode disposed in the first transmissive area and positioned on a first side of the display cathode electrode;
a second touch cathode electrode disposed in the second transmissive area and positioned on a second side of the display cathode electrode;
an encapsulation layer disposed on the display cathode electrode, the first touch cathode electrode, and the second touch cathode electrode;
a first touch line overlapping the display cathode electrode, and
a first touch bridge electrically connecting the first touch cathode electrode and the second touch cathode electrode across the pixel area,
wherein the first touch bridge crosses the first touch line and is electrically connected with the first touch line, and
wherein the first touch line is disposed in a metal layer between the substrate and the anode electrode in the pixel area.
