Abstract: An array substrate includes a common electrode line located in a surrounding region, a protected structure located inside the common electrode line, and a first electrostatic protection circuit having a shorting bar electrically connected between the protected structure and the common electrode line for releasing static electricity on the protected structure. A second electrostatic protection circuit is also electrically connected between the protected structure and the common electrode line, and the second electrostatic protection circuit releases static electricity through the common electrode line after the shorting bar is cut off.
