    • A gate driving circuit includes a plurality of stages connected to each other. An m-th stage (‘m’ is a natural number) of the stages includes a pull-up part, a pull-down part, a first holding part and a second holding part. The pull-up part outputs a high voltage of a clock signal as a high voltage of an m-th gate signal in response to a high voltage applied to a first output control part.

The first holding part holds a voltage applied to the first output control part as a second low voltage having a level lower than the first low voltage. The second holding part holds a low voltage of the m-th gate signal to the first low voltage.

    • A gate drive circuit includes plural stages connected together one after each other. Each of the plural stages includes a circuit transistor, a capacitor part, a first connection part and a second connection part. The circuit transistor outputs the gate signal through a source electrode in response to a control signal applied through a gate electrode.
