Abstract:
A gate driving circuit includes a pull-up control part for applying a first previous carry signal to a first node in response to the first previous carry signal, a first pull-up part outputting a clock signal as an N-th gate output signal in response to a signal applied to the first node, a second pull-up part outputting the clock signal as the N-th gate output signal in response to the signal applied to the first node, a carry part outputting the clock signal as an N-th carry signal in response to the signal applied to the first node, a first pull-down part pulling down the signal at the first node to a second off voltage, and a second pull-down part pulling down the N-th gate output signal to a first off voltage, wherein one of the first pull-up part and the second pull-up part is selectively activated.
