Abstract
Provided are a shift register unit, a gate driving circuit and a display device, wherein the shift register unit includes: a pull-up module connected to a clock signal line and a signal output terminal; at least two pull-down modules both connected to a low level signal line and the signal output terminal; a control module connected to the pull-up module and the pull-down modules, for controlling the pull-up module to be turned on, so that the pull-up module outputs a high level signal input from the clock signal line to the signal output terminal, and for controlling the at least two pull-down modules to be turned on alternatively, so that the at least two pull-down modules output a low level signal input from the low level signal line to the signal output terminal, and for controlling one of the at least two pull-down modules to be turned on while controlling the other pull-down modules of the at least two pull-down modules to be discharged. The shift register unit can reduce over-bias of a gate of a pull-down TFT effectively, thus improving stability of the shift register unit.
