Abstract
A display panel is provided, including a display area, a non-display area, signal lines arranged in the display area, test pads, test lines arranged in the non-display area, and first electrostatic protection units. Each test line is electrically connected to each respective signal line. One end of each test pad is electrically connected to each respective test line. Another end of each test pad is electrically connected to a common line. One end of each first electrostatic protection unit is connected to the corresponding test pad, and another end of each first electrostatic protection unit is electrically connected to the common line. By placing the first electrostatic protection units on one side of the test pads away from the display area, when testing the display panel through the test pads, the first electrostatic protection units effectively protect circuits of the display panel and prevent issues such as ESD electrostatic damage.
