Abstract: In a gate driving circuit and a display apparatus, the gate driving circuit comprises a plurality of stages. At least one of the stages comprises a pull-up section responsive to a first node signal; a pull-down section responsive to a second input signal; a discharging section discharging the first node signal in response to the second input signal; a first holding section responsive to the first clock signal, maintaining the first node signal at the off-voltage; and a second holding section responsive to the second clock signal, maintaining the first node signal at the off-voltage. The second holding section has a greater transistor width-to-length ratio than the first holding section. Therefore, an abnormal gate-on signal is less likely to occur, reducing driving defects of the display apparatus.

Abstract: In a gate driving circuit and a display apparatus having the gate driving circuit, a pull-up transistor of a present stage among plural stages, which are connected one after another to each other and sequentially output a gate signal, pulls up a present gate signal output through an output terminal to a gate-on voltage. A buffer transistor is connected to a control terminal of the pull-up transistor to receive a previous output signal from a previous stage and to turn on the pull-up transistor. The buffer transistor has a chargeability that is about two times or greater than the chargeability of the pull-up transistor. Thus, the size of the pull-up transistor may be reduced, thereby preventing a malfunction of the gate driving circuit when the gate driving circuit is operated under conditions of high temperature or low temperature.
