Abstract
The present disclosure relates to a gate driver and an organic light-emitting display device including same. A gate driver according to an embodiment of the present disclosure includes a plurality of stages. Each of the stages includes: a first pull-up transistor configured to output a carry clock to a first output terminal as a carry signal while a Q node is bootstrapped to a voltage higher than a gate on voltage; a second pull-up transistor configured to output a scan clock to a second output terminal as a scan signal while the Q node is bootstrapped; and holding transistors configured to operate based on a voltage of a QB node, which QB node is charged and discharged in a manner reverse to that of the Q node. The holding transistors are connected to the second output terminal and the Q node, and the holding transistors are electrically isolated from the first output terminal.
