Abstract: A shift register, a driving method, a gate driving circuit and a display device are disclosed. The input module controls the potential of the first node. The first reset module controls the potential of the first node. The second reset module controls the potential of the driving signal output terminal. The first output module controls the potential of the driving signal output terminal under the control of the first node. The second output module controls the potential of the driving signal output terminal under the control of the second node. The pull-down driving module controls the potentials of the first node and the second node. Since the node control signal at the node control signal terminal can eliminate the noise on the first node resulting from the change in the first clock signal, the output stability of the shift register can be improved.
