Abstract:
A gate driving circuit includes a shift resister having stages cascade-connected to one another. Each stage includes a pull-up part, a first pull-up driving part, a first pull-down part and a first ripple prevention part. The pull-up part outputs a high value of a first clock signal to a first output terminal. The first pull-up driving part applies a low value to a control electrode of the pull-up part to turn off the pull-up part. The first pull-down part applies the low value to the signal outputted to the first output terminal. The first ripple prevention part applies the low value of the first input signal to the control electrode of the pull-up part to turn off the pull-up part, and prevents ripple from occurring at the control electrode of the pull-up part. Thus, an abnormal gate-on signal is prevented, to reduce driving malfunction of a display apparatus.
