An array substrate comprises a common electrode, an insulation layer, and a sensing layer, the common electrode comprises the touch electrodes, they are in spaced arrangement, the sensing layer comprises the touch traces and the suspending traces, the touch trace is disposed above the touch electrode and electrically connects to the touch electrode by the through hole, the suspending trace is disposed above the interval between two of the touch electrodes and electrically connects to the touch trace by the first trace. Using the electrical connection between the suspending trace and the touch trace, the electrical potentials of the suspending trace and the touch electrode are the same, the difference of the electric field between the interval area of the adjacent touch electrodes and the touch electrode decreases for avoiding the electric field formed in the data line under the touch electrode ingresses into the liquid crystal layer.
