Abstract
A stage circuit including an input unit controlling voltages of a first node and a second node by using a shift pulse or a gate start pulse input to a first input terminal, a first clock signal input to a second input terminal, a second clock signal input to a third input terminal, a first power supply input to a first power supply input terminal and a second power supply input to a second power supply input terminal, and a first output unit receiving a third clock signal from a fourth input terminal and the second power supply from the second power supply input terminal and outputting a high-level scan signal to a first output terminal corresponding to the voltages of the first node and the second node.
