Abstract
A touch display device includes a substrate defining an active area and a non-active area around the active area; a touch pad in the non-active area; a plurality of signal lines; a signal line insulation layer; first electrodes; at least one noise reduction electrode on the signal line insulation layer and in a portion other than the area corresponding to the first electrodes; a second electrode over the plurality of first electrodes and the at least one noise reduction electrode; an encapsulation layer on the second electrode; touch lines on the encapsulation layer and connected to the touch pad; and touch electrodes on the encapsulation layer and electrically connected to at least one touch line. The encapsulation layer has a sloped surface between the touch pad and the touch electrodes, and the touch lines are arranged on the sloped surface of the encapsulation layer having a corresponding slope.
