Abstract: A shift register, a gate driver circuit, and a display device are disclosed. In the shift register, when a pull-up node is at a low level, a third signal control end controls a conduction of a first noise reduction module and provides the pull-up node with a low-level signal of a first power supply end, so as to pull down a signal of the pull-up node to reduce noise. Therefore, an issue of noise interference on an output end of a gate driving signal is solved when a clock signal provided by a clock signal end is at a high level.
