A GOA circuit includes an output module in which a second TFT is arranged. The second TFT has a drain connected to a source of a first TFT, a gate receiving a first control signal, and a source receiving an Mth clock signal. The first control signal controls the second TFT to turn on and off. Alternatively, the drain of the second TFT is connected to the source of the first TFT, the gate receiving the Mth clock signal and the source connected to the first node to allow the second TFT to be conducted on only when the Mth clock signal is a high voltage and the first node is of a high voltage and is cut off at the remaining time. It is possible to prevent a voltage difference from being induced between the source and drain of the first TFT to reduce the electric current stress.
