Disclosed is an array substrate. The array substrate includes a substrate and a pixel unit array. A first side of each row of pixel units is provided with a first scanning line corresponding to the row of pixel units, and the first scanning line is connected to switch elements of first-type pixel units in the row of pixel units; and the second side of each row of pixel units is provided with a second scanning line corresponding to the row of pixel units, and the second scanning line is connected to switch elements of second-type pixel units in the row of pixel units. An active layer structure of the switch element of a second-type pixel unit in an ith row of pixel units has a common region with an active layer structure of the switch element of a first-type pixel unit in an (i+1)th row of pixel units.
