Abstract
A pixel includes a first transistor coupled between a first power source and a first node, the first transistor including a gate electrode coupled to a second node, an organic light emitting diode (OLED) coupled between the first node and a second power source, a second transistor for supplying a data signal to the second node in response to a scan signal, a third transistor having a source electrode and a drain electrode electrically coupled to each other, the third transistor being coupled to the first power source and the second node, and a fourth transistor having a source electrode and a drain electrode electrically coupled to each other, the fourth transistor being coupled between the second node and the first node.
