Abstract: A display panel is provided having a built-in touchscreen and a touch display device including the same. The display panel has a touch electrode structure allowing parasitic capacitance to be dispersed to a greater number of gate lines, which form parasitic capacitance together with touch electrodes, without concentrically relying on specific gate lines. Differences in load between gate lines are reduced to improve image quality.
