Abstract: A GOA circuit includes GOA circuit units. A holding module is substituted for a capacitor in each GOA circuit unit. A second transistor in the holding module is turned on when a scanning signal does not produce a pulse so that voltage imposed in a first control node is held by a first transistor and a third transistor. Because the transistors form a passage between the first control node and a first constant voltage, the voltage imposed on the first control node does not vary due to electricity leakage. Because a second capacitor is coupled with the first control node, the pulse of the scanning signal output by the GOA circuit unit reaches to an ideal high voltage level. The GOA circuit unit can resolve the problem of easy leakage of electricity. When the scanning signals are output by the GOA circuit unit, the stability is highly ensured.
