Abstract:
A gate driving circuit including first through (N)th stages is provided. An (M)th stage of the first through (N)th stages includes a pull-up control part, a pull-up part, a carry holding part, a carry part, and a first pull-down part. The pull-up control part applies a second node signal of a second node to a first node in response to the second node signal. The pull-up part outputs a clock signal as an (M)th gate output signal in response to the first node signal. The carry holding part applies the (M)th gate output signal to the second node in response to the (M)th gate output signal. The carry part outputs the clock signal as an (M)th carry signal in response to the first node signal. The first pull-down part pulls down the (M)th gate output signal to a first off voltage.
