The array substrate comprises: data lines and scanning lines in an insulating crossing arrangement, where the data lines comprise first data lines and second data lines, the first data lines are arranged in a same layer with the scanning lines; the second data lines electrically connecting the first data lines via first via holes; first signal lines and common electrodes arranged on a substrate, where the first signal lines are arranged insulating from and in a same layer with the second data lines, the first signal line comprises a main portion and a bending portion which is arranged adjacently to the second data line; and a second insulating layer arranged between the first signal lines and the common electrodes, where second via holes are arranged in the second insulating layer, and the common electrodes are electrically connected to the first signal lines via the second via holes.
