Abstract
A gate driving circuit includes a pull-up control part, a pull-up part, a carry part, a first pull-down part and a second pull-down part. The pull-up control part applies a carry signal from a previous stage to a first node. The pull-up part outputs an N-th gate output signal based on a clock signal. The carry part outputs an N-th carry signal based on the clock signal in response to the signal applied to the first node. The first pull-down part includes a plurality of transistors connected to each other in series. The first pull-down part pulls down a signal at the first node to a second off voltage in response to a carry signal of a next stage. The second pull-down part pulls down the N-th gate output signal to a first off voltage in response to the carry signal of the next stage.
