摘要： A shift register circuit includes a first pull-down control sub-circuit and a first noise reduction sub-circuit. The first pull-down control sub-circuit includes a first transistor and a second transistor, and a ratio of a width-to-length ratio of a channel of the second transistor to a width-to-length ratio of a channel of the first transistor is greater than 5:1. The first pull-down control sub-circuit transmits, in response to a first voltage signal received at a first voltage signal terminal, the first voltage signal to a first pull-down node through the first transistor, and transmits a second voltage signal received at a second voltage signal terminal to the first pull-down node through the second transistor under control of a voltage of a pull-up node. The first noise reduction sub-circuit transmits the second voltage signal to the pull-up node under control of a voltage of the first pull-down node.
