Abstract:
An organic light emitting element having a resonator structure in a direction perpendicular to a substrate of said light emitting element, said resonator structure being composed by sandwiching an organic thin film in said light emitting element between reflectors, said organic light emitting element comprising:one of a periodic line layer structure and a periodic dot layer structure in said organic thin film and a part of thin films formed on the top face and bottom faces of the organic thin film, in which line layers or dot layers are periodically arranged in parallel to said organic thin film, wherein each two line layers neighboring each other or each two dot layers neighboring each other have different material compositions or material structures, and a period of said layer arrangement, which is represented by an optical length expressed as a geometrical length.times.a refraction index in material of each layer, is substantially 1/4 of a wavelength in each layer of light emitted in said organic thin film.
