Abstract: A pixel includes first to fourth transistors and a driving transistor. The first transistor is connected between a data line and a first node and has a gate electrode to receive a scan signal. The driving transistor is connected between the first node and a second node and has a gate electrode connected to a third node. The second transistor is connected between the second and third nodes and has a gate electrode to receive the scan signal. The third transistor is connected between first power and the first node and has a gate electrode to receive an emission signal. The fourth transistor is connected between the first and second nodes and has a gate electrode to receive an initialization signal. An organic light emitting diode is connected between the second node and second power. A storage capacitor is connected between the first power and third node.
