Organic light emitting element and light emitting device using the same

摘要

Low cost organic light emitting elements that are bright and have low electric power consumption, and an organic light emitting device using the organic light emitting elements, are provided. Organic light emitting elements capable of converting triplet state excitation energy into light emission are manufactured by applying a binuclear complex having triplet excitation state electrons to the organic light emitting elements. Further, a light emitting device is manufactured using the light emitting elements. Production costs are lowered by using a low cost metal as a central metal of the binuclear complex.
