1. A method of a driving a light emitting device, the light emitting device comprising a plurality of first pixels electrically connected to a first line and a second line, a plurality of second pixels electrically connected to a third line and a fourth line, each of the plurality of first and second pixels comprising a light emitting element and a transistor electrically connected to the light emitting element, the method comprising:

  • applying a first potential to the first line;

    applying a second potential to the second line, wherein the second potential is a constant potential;

    applying a third potential to the third line;

    applying a fourth potential to the fourth line, wherein the fourth potential is a constant potential,wherein each of the light emitting elements included in the first and second pixels emits a light when the first potential is different from the third potential,wherein each of the light emitting elements included in the first and second pixels does not emit a light when the first potential is the same as the third potential,wherein the second potential is different from the fourth potential, andwherein the transistor is operated in a saturated region when the light emitting element emits light.
