<P>PROBLEM TO BE SOLVED: To disclose a shift register and a gate line drive device related to a technology field for a liquid crystal display which improve image quality by reducing an on-error of a gate line. <P>SOLUTION: The shift register includes a first thin film transistor, a second thin film transistor, a third thin film transistor, a capacitor, a feedback module, and a switch module. The feedback module receives a trigger signal of the feedback module of a previous stage and a clock signal, pulls up a level of a first node which becomes a pull-up node, and outputs a feedback signal to a shift register of a previous stage and a trigger signal to the feedback module of a next stage. The switch module maintains an output terminal of the shift register of a present stage to a low level when the shift register of the present stage does not operate. The present invention is applied to an liquid crystal panel. <P>COPYRIGHT: (C)2011,JPO&INPIT |
