Abstract
The present disclosure provides a shift register unit, a gate driving circuit and a display device. The shift register unit provided by the present disclosure includes: an input sub-circuit, an output sub-circuit, at least one pull-down control sub-circuit, at least one pull-down sub-circuit, at least one first noise reduction sub-circuit, and a reverse bias sub-circuit; the reverse bias sub-circuit is configured to control transistors in at least part of sub-circuits connected to a pull-up node to be in a reverse bias state through a power voltage signal in response to a potential of the pull-up node, or control the transistors in at least part of the sub-circuits connected to the pull-up node to be in the reverse bias state through a cascade signal in response to a potential of a cascade signal terminal.
