Abstract

A shift register unit and a driving method thereof, a gate driving circuit, and a display device are provided. In the shift register unit, the input circuit inputs an input signal to a first node; the output circuit outputs an output signal to an output terminal; the first control circuit performs a first control on a level of a first control node; the first noise reduction control circuit controls a level of a second node; the second control circuit performs a second control on a level of a second control node; the second noise reduction control circuit controls a level of a third node; the first voltage-stabilizing circuit performs a third control on the level of the second control node, and the second control and the third control cause at least part of the second noise reduction control circuit to be in different bias states.
