The present disclosure relates an array substrate and a liquid crystal panel. A plurality of sets of gate lines are arranged on the array substrate, each set of gate line at least includes a first gate line and a second gate line, each set of gate line is arranged corresponding to a switch unit, the switch unit is alternately applied the inputted scanning signal on the first gate line and the second gate line. Through the above-describe manner, the present disclosure is possible to resolve the problems of the image sticking and the inconsistent of the left and right eyes brightness when the large-size panel displaying the 3D image, and thus enhance the quality of 3D image.
