Abstract
A scan driver includes a plurality of stages. Each of the plurality of stages includes a control circuit which controls a voltage of a first node and a voltage of a second node in response to an input signal, a first clock signal and a second clock signal, a carry output circuit which outputs a carry signal in response to the voltage of the first node and the voltage of the second node, an enable node controlling circuit which controls a voltage of an enable node in response to the carry signal, an enable signal and an inverted enable signal, a masking circuit which controls a voltage of a third node in response to the voltage of the second node and the voltage of the enable node, and a scan output circuit which outputs a scan signal in response to the voltage of the first node and the voltage of the third node.
