An array substrate includes a plurality of data lines arranged along a row direction to input data signal, a plurality of scanning lines arranged along a column direction to input scanning signals, and a plurality of pixels. Each of the pixels includes a first sub-pixel, a second sub-pixel, a third sub-pixel, and a fourth sub-pixel horizontally arranged along the data lines in turn. And each of the sub-pixels respectively connects to one data lines and one scanning lines. When entering a 3D display mode, the data lines cooperatively operates with the scanning lines so that one of the sub-pixels displays a black image to form an equivalent black matrix. A liquid crystal device including the array substrate is also disclosed. The above array substrate and the liquid crystal device may satisfy the view angle requirement and reduce the crosstalk between two eyes.
