Abstract
A shift register unit, a method for driving a shift register unit, a gate driving circuit, and a display device are provided. The shift register unit includes: a second noise reduction control circuit. The second noise reduction control circuit includes: a first control circuit, configured to transmit a first voltage to a second noise reduction control node; a first coupling circuit, configured to store a level of the second noise reduction control node and adjust the level of the second noise reduction control node; a second coupling circuit, configured to reduce an adjustment magnitude of the first coupling circuit in case of adjusting the level of the second noise reduction control node; a transmission circuit, configured to connect the first noise reduction control node and the second noise reduction control node; and a storage circuit, configured to store the level of the first noise reduction control node.
