Abstract
A shift register unit, a driving method, a gate drive circuit and a display device are provided. The shift register unit includes: an input sub-circuit used to control an electric potential of the pull-up node, an output sub-circuit used to input a first clock signal from a first clock signal terminal to the output terminal, a pull-down control sub-circuit used to control an electric potential of the pull-down node, a pull-down sub-circuit used to control electric potentials of the pull-up node and the output terminal, a first reset control sub-circuit used to control an electric potential of the second control node under control of the first control node and a reset signal from the reset signal terminal and a reset sub-circuit used to control the electric potential of the pull-up node. The shift register unit improves the noise reduction efficiency at the output terminal.
