Abstract
A scan driving circuit includes multiple stages. A j-th stage of the stages includes a buffer part electrically connected to an output terminal that operates in response to a potential of a first control node, a holding part electrically connected to the output terminal that operates in response to a potential of a second control node, and an inverter part electrically connected to the first and second control nodes that controls the potentials of the first and second nodes. The inverter part includes a control transistor including a gate electrically connected to the first control node, and a drain electrically connected to a first voltage terminal that receives a first low voltage or a second voltage terminal that receives a second low voltage. The control transistor includes a dummy gate that receives a low voltage lower than or equal to the first and second low voltages.
