Abstract: A liquid crystal panel and the array substrate thereof are disclosed. The array substrate includes a switch controller respectively connects with the first scanning line and the second scanning line. In the 2D displaying mode, the switch controller turns on the first scanning line and the second scanning line in turn. In the 3D displaying mode, the switch controller turns on the first scanning line, and turns off the second scanning line. With such configuration, the flicker issues in the 3D displaying mode may be improved and the manufacturing cost is prevented from getting higher.
