Abstract: Disclosed are a gate driving circuit, a driving method thereof, and a display device which comprises the gate driving circuit. In the gate driving circuit, the Qn node in the nth stage circuit is precharged when an output signal of a Qn−1 node in a previous stage driving circuit and an output signal of a Qn+1 node in a next stage driving circuit are both in a high-level state. Both the Qn−1 node and the Qn+1 node are at low levels when the gate driving circuit is in an All Gate On display state, and thus a possibility of current leakage from the Qn node can be substantially reduced.
