Abstract
A shift register unit includes an input sub-circuit, a pull-down node driving sub-circuit and an output sub-circuit. The pull-down node driving sub-circuit includes a first connection unit, a first voltage-reduction unit and a second connection unit, and configured to: under the control of the first voltage signal terminal and the pull-up node, transmit a first voltage signal from the first voltage signal terminal to the first pull-down node via the first connection unit, and reduce a voltage applied to the second connection unit via the first voltage-reduction unit; and transmit a second voltage signal from the second voltage signal terminal to the first pull-down node via the second connection unit under the control of the pull-up node.
