Transparent touch display device

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;
• and
• a first touch line overlapping the display cathode electrode,
• wherein the first touch line is disposed in a metal layer between the substrate and the anode electrode in the pixel area,
• wherein the display cathode electrode includes a plurality of openings,
• wherein the first touch cathode electrode is disposed in an inner space of a first opening among the plurality of openings of the display cathode electrode, and
• wherein the second touch cathode electrode is disposed in an inner space of a second opening among the plurality of openings of the display cathode electrode.
