Abstract
Provided is a gate driving circuit including cascade-connected stages that output gate signals. An n-th one of the stages ('n' is a natural number) includes a pull-up part, a pull-up controller, a first pull-down part, a second pull-down part, and a pull-down controller. The pull-up part outputs a first clock signal as an output signal of the n-th stage. The pull-up controller selectively applies first and second powers to a control electrode of the pull-up part. The first pull-down part pulls down a voltage applied to the control electrode of the pull-up part to an off voltage. The second pull-down part pulls down a voltage applied to an output electrode of the pull-up part to the off voltage. The pull-down controller selectively applies the first and second powers to control electrodes of the first and second pull-down parts.
