Abstract
A scan driver includes a plurality of stages, each of the plurality of stages including: a first controller to control voltage levels of a first control node and a second control node in response to a first start signal and a second start signal, and to output a first carry signal; a second controller to control voltage levels of a third control node and a fourth control node in response to the first start signal and the second start signal, and to output a second carry signal; and an output circuit including: a pull-up transistor having a gate connected to the first control node; and a pull-down transistor having a gate connected to the third control node. The output circuit is to output a scan signal based on an on voltage output through the pull-up transistor and an off voltage output through the pull-down transistor.
