Abstract
A display panel includes: gate and data lines; pixels connected to the gate and data lines; and a stage includes: a pull-up driver including an output terminal of the stage and which outputs a gate-on voltage, an output pull-down unit which pulls down an output terminal of the stage, a reset unit which changes a voltage of a second node into a low voltage based on a voltage of the output terminal of the stage, a first node pull-up unit which changes a first node into a high voltage based on a gate-on voltage from a previous stage, a first node pull-down unit which changes the first node into the low voltage based on the gate-on voltage from a subsequent stage, and a first node reset unit which changes the voltage of the first node into the low voltage based on the voltage of the second node.
