Abstract
The present disclosure discloses a gate drive circuit and a display panel. The gate drive circuit includes a plurality of shift registers. Each shift register includes a level transmission signal selection module, a pull-up control module, a pulse quantity reduction module, a first inverting module, a first output module, a second output module, and a voltage boosting module. By connecting the voltage boosting module between a second electrode of a second transistor and a low potential line in series, when a first transistor is turned on, a potential of the second electrode of the second transistor can be increased, and on-state current of the second transistor can be reduced, so that a pulse amplitude of a second gate drive signal can be increased and stabilized.
