Abstract: A pixel capable of stably compensating for a threshold voltage is disclosed. The pixel includes an organic light emitting diode (OLED), a driving transistor having a gate electrode, a source electrode, and first and second drain electrodes. The pixel also has a plurality of second transistors serially coupled between the first drain electrode and a gate electrode of the driving transistor, and a node electrically coupled to the second drain electrode and to each of the second transistors.
