Abstract

A shift register is provided that outputs a gate driving pulse even if a start pulse provided to a first stage is not synchronized with a clock pulse. The shift register has multiple stages that sequentially output gate driving pulses. At least one stage includes a first switching device turned-on by a first clock signal and applying the start pulse to a first node. A second switching device is turned-on by the first clock signal and applies a first supply voltage to a second node. A third switching device is turned-on by the start pulse applied to the first node and outputs a second clock signal. A fourth switching device is turned-on by the first supply voltage and outputs a second supply voltage. A fifth switching device is turned-on by the start pulse and applies the start pulse to the first node.
