Scan driver and display device including the same

Abstract

A scan driver includes stages which sequentially output scan signals to scan signal lines during an active period of an N-th frame, and at least one of the stages includes an output node controller that supplies a gate-on voltage to a pull-up node in response to a gate control signal of a display driver, and an output controller that supplies a scan signal to a scan signal line by outputting a scan clock signal, which is input through a scan clock terminal, to the scan signal line in case that the gate-on voltage is supplied to the pull-up node, wherein the output node controller includes a thin-film transistor which is turned on in response to a simultaneous driving control signal, supplies the scan clock signal to the pull-up node, and periodically receives the scan clock signal in case that the thin-film transistor is turned off during the active period.
