Abstract:
Disclosed are a gate driving circuit and a liquid crystal display device. The gate driving circuit comprises multi-stages of gate driving units. A gate driving unit at each stage includes a pull-down holding module which maintains an electric potential at an output terminal of a gate driving unit at a present stage at a negative electric potential. The influence of a right drift of a threshold voltage of an eighty-second transistor on the gate driving unit can be avoided, and further a speed of pulling down an electric potential at a first node can be increased.
