Abstract

A gate drive circuit includes a shift register having stages connected to each other in series. An (m)-th stage ('m' is a natural number) includes an output part, a discharging part, a first holding part and a second holding part. The output part outputs the first clock signal as a gate signal in response to a first clock signal provided from an external device and discharges the gate signal in response to a second input signal. The output part includes a first transistor having a first channel length. The discharging part discharges a signal of the first node to the second voltage level. The first holding part maintains a signal of the first node at a level of the gate signal, and is discharged to the second voltage level. The first holding part includes a second transistor having a second channel length that is longer than the first channel length. The second holding part maintains a signal of the first node at a level of the second voltage level.
