A GOA circuit includes multiple GOA circuit units, each of which includes a pull-down holding module to hold the voltage level of the second control node during the non-scanning period, so to keep the scan signal at a low voltage level. The GOA circuit unit uses a first transistor and a second transistor, operating along with a first clock signal and a second clock signal, so that a pull-down holding module continues outputting signals so to turn on the pull-down module when the scan signal is in the period that does not need to output pulses. Therefore, during the period when the scan signal does not need to output pulses, the pull-down module is still turned on and pulls down the voltage level. The present disclosure solves the problem that the pull-down holding module cannot operate continuously, and improves the stability in outputting scan signals of GOA circuit units.
