Abstract
A liquid crystal display device and a gate driving circuit are disclosed. The gate driving circuit includes multiple-stage gate driving units and a control chip. Each stage gate driving unit includes a first pulling control unit, a first pulling unit, a second pulling control unit, a second pulling unit, a first control unit, a second control unit and a third control unit. The control chip is used for pulling a first clock signal and a first voltage reference signal to a first voltage level. Accordingly, the scanning lines driven by the gate driving circuit are all turned on in order to stably realize an All-Gate-On function.
