Abstract
A scan driver includes stages including an input block to change a first node voltage to a gate on voltage based on an input signal, a second node control block to control second node voltage based on a first clock signal and the first node voltage, a scan output block to output a second clock signal as a scan signal based on the first node voltage, and to output a first gate off voltage as the scan signal based on the second node voltage, a carry output block to output the second clock signal as a carry signal based on the first node voltage, and to output a second gate off voltage different from the first gate off voltage as the carry signal based on the second node voltage, and a first node control block to transfer the carry signal to the first node based on a next carry signal.
