Classification: CPC G  H | IPC G  H

Claim 0:
1. A scan driver comprising:
a plurality of stages,
wherein each of the plurality of stages comprises:
a first node controller controlling a voltage of a first node by using first and second clock signals;
a second node controller controlling a voltage of a second node by using the first and second clock signals, an output clock signal, and a start signal;
an output buffer unit including a first transistor and a second transistor; and
a third node directly connecting to the first node through a tenth transistor,
wherein the first transistor outputs a gate low voltage as a scan signal while the second node is activated,
the second transistor outputs a gate high voltage of the output clock signal as the scan signal while the third node is activated, and
wherein a rising edge or a falling edge of the output clock signal is synchronized with a falling edge of the first clock signal or a falling edge of the second clock signal.
