Gate driver and display panel having the same

Abstract

A display panel includes pixels connected to gate lines, and a gate driver that supplies a gate signal to at least one of the gate lines and includes a plurality of stages. Each stage includes a pull-up transistor to apply a turn-on voltage of a first clock signal to an output terminal responsive to a voltage at a Q-node, a pull-down transistor to apply a turn-off voltage to the output terminal responsive to a voltage at a QB-node that holds the turn-on voltage during a period in which the output terminal is applied the turn-off voltage, and a QB-node control unit to apply the turn-on voltage to the QB-node responsive to the first clock signal and a second clock signal in reverse-phase with the first clock signal. Accordingly, a display panel may include a gate driver that can set, reset, and hold the voltage at a QB-node.
