Abstract:
A gate drive circuit includes a shift register having a plurality of stages, in which an n-th stage (‘n’ is a natural number) of the plurality of stages is connected to at least one subsequent stage. The n-th stage includes a pull-up part configured to output a high voltage of an n-th gate signal using a high voltage of a clock signal as in response to a high voltage of a control node, a control pull-down part configured to pull-down a voltage of the control node into a low voltage in response to a carry signal outputted from at least one of next stages of the n-th stage and receiving a back-bias voltage corresponding to the low voltage, and a carry part configured to output the high voltage of the clock signal as an n-th carry signal in response to a high voltage of the control node.
