Abstract
A shift register circuit includes a noise reduction sub-circuit and a pull-down node control sub-circuit. A control end of the noise reduction sub-circuit is connected to a pull-down node, the noise reduction sub-circuit is connected to a first voltage input end. The pull-down node control sub-circuit includes a first pull-down node control sub-circuit and a second pull-down node control sub-circuit. The second pull-down node control sub-circuit controls the pull-down control node to be connected to a first clock signal input end when the first clock signal input end inputs a first level, the pull-down node to be connected to the first clock signal input end when a potential of the pull-down control node is at the first level, so that the potential of the pull-down node is at a first level and a noise reduction transistor included in the noise reduction sub-circuit is turned off.
