Abstract
The present disclosure relates to a display panel, a liquid crystal display device and a test method thereof. The display panel includes a display area and a GOA circuit area. The GOA circuit area includes a plurality of GOA units arranged on a TFT substrate and metal areas arranged at positions of a CF substrate corresponding to the GOA units, which constitute capacitor structures with the GOA units. The display panel further includes signal lines electrically connected with the capacitor structures and test points elicited through the signal lines. By means of the above configuration, the position where short circuit/open circuit occurs in the GOA circuit area can be found quickly by monitoring the voltage on the test point, thereby shortening the time of seeking ESD and short circuit/open circuit, increasing the analyzing and improving speed.
