Display device for preventing arcing between boundary surface of mask for covering pad area and pad electrode and method of manufacturing the same

A display device comprising:

• a first substrate including a display area and a non-display area adjacent to the display area, wherein a plurality of pixels are arranged at the display area;
• a pad area arranged in the non-display area;
• a dam disposed between the display area and the pad area;
• an organic light emitting diode provided in the display area;
• an encapsulation layer disposed on the organic light emitting diode;
• an insulating layer disposed on the encapsulation layer and provided in the display area;
• a touch electrode disposed on the insulating layer;
• and
• a touch line disposed on the insulating layer and provided between the display area and the pad area;
• and
• a passivation layer disposed on the touch electrode,
• wherein the insulating layer is extended to the pad area,
• wherein the touch line is electrically connected to the pad electrode provided in the pad area,
• wherein the touch line contacts the pad electrode through a pad contact hole, and
• wherein the pad contact hole is disposed in the pad area and passes through the insulating layer.
