1. Alight emitting device comprising:

  • a light emitting element comprising;

    a first electrode;

    a second electrode; and

    a light emitting layer comprising an organic compound between the first and the second electrodes;

    wherein the light emitting element emits light by applying a voltage between the first electrode and the second electrode;

    means for applying a forward bias for emitting light from the organic light emitting element and a reverse bias of reverse polarity to the forward bias, wherein a maximum voltage Vf of the forward bias is higher than a maximum voltage Vr of the reverse bias in an alternating current cycle formed of the forward bias and the reverse bias.
