Abstract:
A gate driving circuit includes a plurality of stages, each stage including an input unit to determine a level of voltage to input to a first node based on the first and second input signals and the first clock signal that is input according to the level of the voltage input to the first node and a first gate-off voltage that is input in response to the second clock signal, a second driving unit outputting the gate signals based on the third clock signal input according to the voltage input to the first node and a second gate-off voltage input in response to the second clock signal, and a leakage blocking unit blocking leakage current of a transistor by maintaining a level of voltage input to a third node connected to the first node via at least one transistor.
