Claim 19:
20. A scan driver comprising:
a plurality of stage groups configured to supply scan signals to scan lines based on clock signals, carry clock signals, a first power, and a second power,
wherein a first stage group of the stage groups comprises:
a first stage configured to supply a first scan signal to a first scan line by controlling a voltage of a third node based on an input signal, a first clock signal of the clock signals, a first carry clock signal of the carry clock signals, the first power, the second power, and a voltage of a first node or a second node;
a second stage configured to supply a second scan signal to a second scan line by controlling a voltage of a fourth node based on the input signal, a second clock signal of the clock signals, a second carry clock signal of the carry clock signals, the first power, the second power, and the voltage of the first node or the second node; and
an output control circuit configured to control the voltage of the first node and the voltage of the second node based on a first node control signal, a second node control signal, the first power, the second power, the voltage of the third node, and the voltage of the fourth node.
