Abstract:
A display panel includes a plurality of pixels each including a first transistor between a first node and a second node and having a gate electrode to receive the scan signal, a second transistor between the second node and a third node in series with the first transistor and having a gate electrode to receive the initialization control signal, a driving transistor between the first power voltage providing line and the third node and having a gate electrode connected to the first node, a third transistor between the third node and a fourth node and having a gate electrode to receive the emission control signal, an organic light emitting diode, between the fourth node and the second power voltage providing line, a first capacitor between the first power voltage providing line and the first node, and a second capacitor between the second node and one of the data lines.
