Abstract
An embodiment of the present invention discloses a shift register unit and a gate drive device for a liquid crystal display. The shift register unit, on the basis of a structure of 12 transistors and 1 capacitor in the prior art, enables both the drain of the seventh thin film transistor and the gate and the drain of the ninth thin film transistor being connected to the second clock signal input terminal, such that a leakage current would not be generated among the seventh thin film transistor, the eighth thin film transistor, the ninth thin film transistor and the tenth thin film transistor when a high level signal is outputted from the shift register unit, thus power consumption of the shift register unit may be reduced.
