Abstract: A gate driving circuit including a driving circuit configured to charge an M node based on a selection signal externally supplied in response to receiving a first carry signal, and charge a Q node with a high voltage responsive to a reset signal and a voltage charged in the M node that corresponds to the selection signal, a node controller configured to control the Q node and a Qb node responsive to driving of the driving circuit, wherein a level of a voltage of the Qb node is opposite to a level of a voltage of the Q node, and an output circuit configured to output a second carry signal and at least one scan signal responsive to voltages at the Q node and Qb node included in the node controller.
