Abstract
Provided is a scan driver of a display device, and the scan driver includes a driving circuit and a masking circuit. The driving circuit includes a control circuit, a first output circuit, and a second output circuit. The control circuit outputs a first control signal and a second control signal. The first output circuit is connected to a first output terminal which outputs a first scan signal and a first voltage terminal and operates in response to a first control signal. The second output circuit is connected to a first output terminal and a second voltage terminal and operates in response to a second control signal. The masking circuit outputs a second scan signal to a second output terminal in response to the first control signal and the second control signal and is connected to an input terminal to which a masking signal is supplied.
