Abstract: A shift register circuit, a driving method thereof, a gate drive circuit and a display device are provided. The shift register circuit includes an input sub-circuit, an output sub-circuit, a discharge sub-circuit and a noise reduction sub-circuit. The input sub-circuit is connected to an input signal terminal, a first power source terminal and a pull-down node, and configured to, under the control of an input signal, output a first power source terminal signal to the pull-down node. In the shift register circuit, the discharge sub-circuit may control the potential of the pull-down node to be an ineffective potential at the input stage, thereby preventing the noise reduction sub-circuit from affecting the potentials of the pull-up node and the output terminal under the control of the pull-down node, and ensuring normal output of the shift register circuit.
