Abstract
An nth (where n is a natural number) stage is included in a scan driver of a display. The nth stage includes: a first input circuit for controlling a voltage of a first node in response to a carry signal of a previous stage; a second input circuit for controlling the voltage of the first node in response to a carry signal of a next stage; a first control circuit for controlling a voltage of an output terminal in response to the carry signal of the next stage; an output circuit for outputting an nth scan signal and an nth carry signal in response to the voltage of the first node and a voltage of a second node; and a leakage control circuit for supplying a control voltage to the first input circuit and the second input circuit in response to one of the nth scan signal and the nth carry signal.
