A GOA circuit is provided. The GOA circuit includes multiple cascaded GOA unit, each stage of the GOA unit is according to a N-staged GOA unit; the N-staged GOA unit comprises a pull-up control circuit, a pull-up circuit, a transmission circuit, a pull-down circuit, a pull-down holding circuit and a bootstrap capacitor; transmission the first reverse clock signal and the first clock signal of pull-down holding circuit have difference potential at each of the same clock, and the second reverse clock signal and the second clock signal of pull-down holding circuit have difference potential at each of the same clock. It could effective reverse correcting the problem of forward deflection of voltage threshold in the pull-down holding sub-circuit of single-stage GOA unit, such that enhances the reliability and stability of GOA circuit.
