Abstract
A shift register and its driving method, a gate driving circuit and a display device, wherein the shift register comprises an input module (1), a reset module (2), a first control module (3), a second control module (4), a first output module (5) and a second output module (6), through which, the shift register makes the potential at the third node (C) for controlling the first output module (5) in a stable status via the first control module (3), and makes the potential at the fourth node (D) for controlling the second output module (6) in a stable status via the second control module (4), thereby achieving stability of the scanning signal outputted by the driving signal output terminal (Output) of the shift register, further reducing noise of the scanning signal outputted by the driving signal output terminal (Output), and improving stability of an output of the shift register.
