Abstract
A GOA circuit and a display panel are provided in the present application. The GOA circuit includes multi-stage cascaded GOA units. An N-th stage GOA unit includes a pull-up control module, a pull-up module, a chamfering control module, and a pull-down module. The chamfering control module is electrically connected to an N-th stage scan signal output terminal to pull down a potential of the N-th stage scan signal before the pull-down module pulling down a potential of a first node and the potential of the N-th stage scan signal, under control of a chamfering control signal and a first reference low level signal.
