Abstract
A shift register and a gate-line drive device relate to liquid crystal display. The shift register comprises: first thin film transistor, second thin film transistor, third thin film transistor, fourth thin film transistor and fifth thin film transistor; capacitor, connected between first node and the output terminal of the present stage; first operation modular, connected between first operation signal terminal and the first node, and connected to the low level signal terminal; second operation modular, connected between second operation signal terminal and the first node, and connected to the low level signal terminal, wherein, the first operation modular and the second operation modular are alternatively operated, and the first operation modular and the second operation modular are used to maintain both of the gate and drain of the second thin film transistor at low level respectively, when the shift register is not operated.
