Disclosed are an array substrate, a driving method of the array substrate, and a display device. The array substrate includes gate lines (12), data lines (11), and pixel units, each of the pixel units includes a common electrode (2, 3) and a pixel electrode (5). The common electrode (2, 3) includes a first common electrode (2) and a second common electrode (3). The first common electrode (2) includes a plurality of first strip electrodes and the second common electrode (3) includes a plurality of second strip electrodes. The first strip electrodes and the second strip electrodes are arranged alternately configured to form electrical fields with the pixel electrode (5) respectively. By disposing the first and second common electrodes forming multi-dimensional electric fields with the pixel electrode respectively, the transmittance of the display device is improved.
