Abstract

A gate driving circuit includes cascaded stages, each including a pull-up part, a carry part, a pull-up driving part, a holding part and an inverter. The pull-up part pulls up a gate voltage to an input clock. The carry part pulls up a carry voltage to the input clock. The pull-up driving part is connected to a control terminal (Q-node) common to the carry part and the pull-up part, and receives a previous carry voltage from a previous stage to turn on the pull-up part and the carry part. The holding part holds the gate voltage at an off-voltage, and the inverter controls at least one of turning on the holding part and turning off the holding part based on an inverter clock. A high level of the inverter clock in a given horizontal period (1H) temporally precedes a high level of the input clock by a predetermined time interval.
