Claim 3:
4. The scan driver of claim 2, further comprising a fourth node controller connected between the third node controller and the first output controller,
wherein the fourth node controller comprises:
a third control transistor, which is connected between the first voltage input terminal and a fourth control node, and of which a gate is connected to the third control node;
a fourth control transistor, which is connected to the second voltage input terminal and the fourth control node, and of which a first gate is connected to the third control node and a second gate is connected to the third voltage input terminal;
a fifth control transistor, which is connected between the first voltage input terminal and a fifth control node, and of which a gate is connected to the fourth control node; and
a sixth control transistor, which is connected between the second voltage input terminal and the fifth control node, and of which a first gate is connected to the fourth control node and a second gate is connected to a fourth voltage input terminal to which a fourth voltage of the second voltage level is applied,
wherein the gate of the first pull-up transistor and the first gate of the first pull-down transistor are connected to the fifth control node, and
the fourth voltage is less than the second voltage.
