Abstract
A scan driver includes a plurality of scan driving blocks. Each of the scan driving blocks includes a first shift register including a plurality of driving transistors, the first shift register being configured to provide a first driving signal to a first driving node and to provide a second driving signal to a second driving node, a second shift register including a plurality of masking transistors, the second shift register being configured to provide a masking signal to a masking output node, and a buffer circuit including a plurality of buffer transistors, the buffer circuit being configured to provide scan signals. The buffer circuit outputs the scan signals that include the first pulse or the scan signals that include the first pulse and the second pulse based on the masking signal.
