The invention provides a GOA circuit. The first node control module of the GOA circuit provided by the invention comprises a tenth TFT, an eleventh TFT and a twelfth TFT of N-type TFTs, when the voltage of the first node is high, the gate-to-source voltage difference of the twelfth TFT is the threshold voltage thereof, so that the drain-source voltage difference of the eleventh TFT is also the threshold voltage of the twelfth TFT, thereby making the resistance between the drain of the tenth TFT and the first node is extremely large, which can avoid the impact of leakage current generated by the tenth TFT on the voltage of the first node when the noise and coupling in the second node occurs, and to ensure the normal output of the scan signal.
