The invention provides a GOA circuit, comprising a plurality of GOA units, for a positive integer n, n-th GOA unit comprising: a first TFT (T1), a second TFT (T2), a third TFT (T3), a fourth TFT T(4), a fifth TFT (T5), a sixth TFT (T6), a seventh TFT (T7), an eighth TFT (T8), a ninth TFT (T9), a first capacitor (C1) and a second capacitor (T2). The invention, based on known GOA circuit, uses T8 and T9 connected in parallel between node H and node Qn for conduction. The gate of T8 is connected to Qn−1 (the output signal of the previous GOA unit), and the gate of T9 is connected to Qn+1 (the output signal of the next GOA unit). The invention can provide the function of the known GOA circuit to prevent the stress on TFT T7, can also prevent the output Gn from instability.
