A pixel circuit is disclosed that includes first through sixth transistors, first and second capacitors, and a light emitting element. A gate electrode of the second transistor receives a first gate signal. A gate electrode of the third transistor receive a second gate signal. Gate electrodes of each of the fourth and fifth transistors receive a third gate signal. A gate electrode of the sixth transistor receives an emission signal. First electrodes of the first transistor and the first capacitor each receive a first power supply voltage. A cathode electrode of the light emitting element receives a second power supply voltage. A first electrode of the fourth transistor receives an initialization voltage.
