Abstract
A scan driver includes a plurality of decoder type stages respectively outputting a plurality scan signals. An n-th stage includes a first input block configured to provide a first DC voltage to a first node in response to a plurality of selection signals, a pull-down block configured to pull down a first node voltage, a second input block configured to reduce a voltage drop of a second node voltage when a scan signal is output, and to provide a second DC voltage to a second node in response to the selection signals, a buffer block configured to output the first node voltage, that is a buffer output voltage, in response to the first node voltage and the second node voltage, and an output block configured to output the scan signal.
