Abstract
The present disclosure relates to a gate driver on array (GOA) circuit and a liquid crystal display (LCD). The GOA circuit includes a plurality of cascaded-connected GOA units connected, and the GOA unit at N-th level includes: a pull-up controlling module, a pull-up module, a down-transfer module, a bootstrap capacitor module, a pull-down maintaining module, a pull-down module and a controlling module. The controlling module respectively connects with the pull-down maintaining module and the adjacent GOA unit, and the controlling module is configured to accelerate a pull-down speed of the pull-down maintaining module by increasing a discharge path of the pull-down maintaining module on the GOA unit at the next level. As such, the response speed of the pull-down maintaining module may be improved, so as to improve the performance of the pull-down maintaining module.
