Abstract:
A GOA circuit and a liquid crystal display apparatus. The GOA circuit comprises a plurality of cascaded GOA sub-circuits, wherein in a pull-down unit (4) of the GOA sub-circuit, connection is carried out by means of the serial connection of a first thin film transistor (T41') and a second thin film transistor (T41). The connection method reduces the leakage current at a Q point in a GOA circuit, improves the stability of the GOA circuit in a severe environment, and enhances the reliability of a liquid crystal panel.
