Abstract
There is provided a scan driver. The scan driver includes stages. An ith (i is a natural number) stage circuit includes an output unit, a controller configured to control the voltage of the second node in response to a kth (k is a natural number) clock signal supplied to a second input terminal, and an input unit configured to control the voltages of the first node and the second node in response to a carry signal of a previous stage that is supplied to a third input terminal and a carry signal of at least one next stage. The kth clock signal maintains a gate on voltage at a point of time at which a voltage of the jth clock signal is changed to a gate on voltage.
