Output stage circuit is added to the gate driving circuit of the LCD. The output stage circuit moderates the falling slope of the gate driving signal so as to reduce the feed-through phenomenon. The output stage circuit includes a discharge circuit which discharges the voltage of the gate driving signal with programmable speeds. The discharge circuit has a plurality of discharge units which are turned on sequentially and designed with different driving abilities. At beginning of falling of the gate driving signal, the discharge circuit discharges the gate driving signal with lower driving ability so that the gate driving signal falls with a lower speed. As time passes, the falling speed of the gate driving signal increases by the increasing of the driving ability of the discharge circuit. The entire falling period of the gate driving signal is prolonged by the output stage circuit and the feed-through phenomenon is eased.
