Stage circuit and emission driver using the same

PURPOSE: A stage circuit and a light emitting control line driver using the same are provided to improve reliability and freely control the width of a light emitting control signal by simplifying a circuit configuration. CONSTITUTION: An output part(100) outputs voltage of a first power supply or a second power supply through a first output terminal. A bidirectional driver(106) receives sampling signals of a previous stage and a next stage. A first driver(102) controls voltage of a first node and a second node. A second driver(104) outputs the sampling signal. The first driver includes a third transistor, a fourth transistor, a fifth transistor, and a third capacitor.
