The first touch zone includes at least one first touch electrode, the second touch zone includes at least one second touch electrode, and at least a portion of the second touch electrode extends into the first touch zone. Thus, areas of the second touch electrode and the first touch electrode are equal or as similar as possible, thereby improving a touch sensitivity and accuracy and a uniformity of display of the touch display panel and the touch display device.
