Abstract: A touch display device and a touch display panel. Touch lines and contact pads are disposed between touch electrodes, arranged in touch electrode lines in the touch display panel, and a driver circuit. A total of the area of each touch line and the area of the corresponding contact pad has a predetermined value. Differences in parasitic capacitance among the touch lines according to the positions of the touch electrodes are compensated for. It is possible to prevent the accuracy of sensing from being lowered by differences in parasitic capacitance among the touch electrodes disposed in different positions.
