Abstract
The present disclosure provides a shift register unit, a gate driver circuit, and a display device, belonging to the field of display technology, which can solve the problem of unstable threshold voltage and current leakage of thin film transistors in existing shift register units. The shift register unit in the present disclosure includes: an input subcircuit, an output subcircuit, a pull-down control subcircuit, a pull-down subcircuit, a first noise reduction subcircuit, a first auxiliary control subcircuit, and a second auxiliary control subcircuit. The first auxiliary control subcircuit is configured to write the third reference level signal to the pull-down control node when the pull-down node is the first reference level signal, and control the pull-down subcircuit to be closed to control the first noise reduction subcircuit to be open.
