Shift register and driving method thereof, gate driving circuit and display device

The invention provides a shift register and a driving method thereof, a gate driving circuit and a display device, and relates to the technical field of display. The shift register can effectively reduce the phenomenon of splash screen or Flicker drift of the display device. The shift register comprises a first output module which is electrically connected with a first reset signal line and an output signal line and is configured to write a reset signal of the first reset signal line into the output signal line under the control of the reset signal of the first reset signal line in a non-display stage; a second output module; a reset module; an input module; a pull-down node control module; a pull-down control module; and a pull-down module. 本发明提供了一种移位寄存器及其驱动方法、栅极驱动电路和显示装置，涉及显示技术领域，该移位寄存器可以有效降低显示装置出现闪屏或Flicker漂移现象。该移位寄存器包括：第一输出模块，电连接第一复位信号线和输出信号线，被配置为在非显示阶段，在所述第一复位信号线的复位信号的控制下，将所述第一复位信号线的复位信号写入所述输出信号线；第二输出模块；复位模块；输入模块；下拉节点控制模块；下拉控制模块；下拉模块。
