1. An array substrate for a touch display device, comprising:
a substrate having a pixel region;
a thin film transistor on the substrate in the pixel region;
a planarizing layer on the thin film transistor;
a metallic touch common line on the planarizing layer;
a first passivation layer on the touch common line, the first passivation layer having a touch common contact hole;
a transparent touch common electrode on the first passivation layer in the pixel region, the transparent touch common electrode contacting the metallic touch common line through the touch common contact hole;
a second passivation layer on the touch common electrode; and
a pixel electrode on the second passivation layer, the pixel electrode connected to the thin film transistor,
wherein the metallic touch common line is exposed by the touch common contact hole and whole area of the transparent touch common electrode are covered with the second passivation layer,
wherein the transparent touch common electrode is formed in the touch common contact hole so that the transparent touch common electrode is directly connected to the metallic touch common line.
