1. A display device comprising:
a first pixel comprising a first electrode initialization transistor and a first light emitting diode to emit light having a first color, the first light emitting diode comprising a first electrode and a second electrode; and
a second pixel comprising a second electrode initialization transistor and a second light emitting diode to emit light having a second color, the second light emitting diode comprising a third electrode and a fourth electrode,
wherein the second electrode of the first light emitting diode and the fourth electrode of the second light emitting diode are configured to receive a first power voltage,
wherein the first electrode of the first light emitting diode is configured to receive a first initialization voltage through the first electrode initialization transistor,
wherein the third electrode of the second light emitting diode is configured to receive a second initialization voltage through the second electrode initialization transistor,
wherein the second initialization voltage is different from the first initialization voltage, and
wherein the first initialization voltage is greater than the first power voltage.
