The present invention provides an array substrate, which comprises a display region and a peripheral wiring region, wherein in the peripheral wiring region, gate driving circuits and data driving lines are arranged respectively in correspondence with scanning lines and data lines in the display region and the gate driving circuits are electrically connected to different metal layers arranged in wire on array of the chip on film region to improve the electrostatic protection of the array substrate. Because the array substrate provided by the present invention comprises the wire on array arranged in different metal layers to extend the length of the wire on array and increase the impedance of the wire on array. Thereby the input current of gate driving circuit can be decreased and the probability of gate driving circuit damage can be reduced, the electrostatic protection of the array substrate can be improved.
