Abstract
A shift register, a gate driving device and a liquid crystal display device aim to solve the problem that the lifespan of the gate driving device is shortened since some transistors in an existing shift register are in a turn-on state all the time during a non-operational period to reduce noise on a corresponding gate line. The shift register includes an output module (12) for connecting a control signal output terminal (OUTPUT) of the shift register and a clock signal input terminal (CLKIN) under the control of the signal output from a driving module (11); a first pull-down module (13) for connecting the pull-up node (PU) and the second level signal input terminal (15) and connecting the control signal output terminal (OUTPUT) of the shift register and the second level signal input terminal (15) under the control of the signal output from a driving module (11); and a second pull-down module (14) for connecting the pull-up node (PU) and the second level signal input terminal (15) and connecting the control signal output terminal (OUTPUT) of the shift register and the second level signal input terminal (15) under the control of the signal output from a driving module (11).
