Abstract
A shift register unit and a gate drive device for a liquid crystal display are disclosed. Both gate and drain of the tenth thin film transistor are connected to the source of the fifth thin film transistor, a source thereof is connected to a low voltage signal input terminal, threshold voltages of the eighth thin film transistor and the ninth thin film transistor are equal to or less than threshold voltage of the tenth thin film transistor. The shift register unit and the gate drive device for liquid crystal display provided in the present invention, could enable the thin film transistor used to suppress the noise in the shift register unit to maintain turning on, therefore it guarantees the reliability of the shift register unit.
