Abstract
The present application discloses a gate drive circuit and a display panel. The gate drive circuit includes a plurality of cascaded gate drive units, in which by adopting a same complex clock signal for a pull-down control module, a maintaining module and a pull-down module, a N-th-stage gate drive unit can rapidly pull down a falling edge of a N-th-stage scan signal to the potential of a constant low voltage level signal and effectively reduces the time required to pull down the N-th-stage scan signal from high voltage level to low voltage level.
