The invention discloses a display panel and a liquid crystal display device. The display panel comprises: a board body, which has a test line, a ground line and a plurality of data lines arranged in parallel inside, wherein the test line is located at one end of the plurality of data lines, on a data binding opposite side of the board body, and the plurality of data lines and the test line are electrically connected through an electrostatic discharge unit; and a transistor, which is disposed in the board body, wherein the source of the transistor is electrically connected with one end of the ground line and the drain of the transistor is electrically connected with the test line to discharge static electricity from the test line and the plurality of data lines to the ground line. When an antistatic quality evaluation experiment of the display panel is performed, since the test line is electrically connected with the drain of the transistor and the ground line is electrically connectedwith the source of the transistor, the static electricity on the test line can be led to the outside by the transistor through the ground line, thereby avoiding the abnormal display of the display panel due to the static electricity inside the display panel.
Description
technical field [0001] This article involves but is not limited to liquid crystal display technology, especially a dismantling jig. Background technique [0002] Existing narrow bezel display products have high antistatic requirements for the display panel, and the display panel needs to be tested for antistatic quality evaluation. Generate static electricity. If there are exposed wires on the display panel, when the exposed wires are charged with an electrostatic gun, the static electricity will be introduced into the display panel through the wires, causing the display panel to display abnormally. [0003] The production process of the display panel: such as figure 1 As shown, when making a Panel (this Panel includes a display panel 1' as an example), in order to improve the defect detection rate of the array test, a test line 2' is added to the opposite side of the data binding of the Panel, and the test line 2 'The test terminal 8 is connected after the Panel is exten...
