Claim 12:
13. The scan driver of claim 11, further comprising:
a fourth node controller, which is connected between the first voltage input terminal and a fourth clock terminal to which a fourth clock signal is applied, and controls a voltage level of a fourth control node according to the voltage levels of the first control node and the second control node; and
a third output controller comprising a third pull-up transistor, which is connected between the first voltage input terminal and a third output terminal and outputs a third gate control signal of the first voltage level to the third output terminal, and a third pull-down transistor, which is connected between the second voltage input terminal and the third output terminal and outputs a third gate control signal of the second level to the third output terminal,
wherein the third pull-down transistor comprises a first gate and a second gate,
a gate of the third pull-up transistor and the first gate of the third pull-down transistor are connected to the fourth control node, and
the second gate of the third pull-down transistor is connected to the third voltage input terminal.
