ABSTRACT:
An apparatus is provided with a plurality of organic light emitting devices, each having an organic light emitting layer that synthesizes two or more colors of light that are complementary to each other thereby producing white light, and a resonant structure by which a resonant wavelength is set to a predetermined wavelength, and outputs the white light via the resonant structure. The apparatus further comprises a plurality of wavelength selection units on a path through which the white light is outputted, each wavelength selection unit transmitting only light of a particular wavelength included in the outputted white light, the predetermined wavelength substantially coinciding with a wavelength corresponding to a primary color whose luminous intensity is, if without the resonant structure, the lowest of three primary colors included in the produced white light to bring it close to white light ideal for an image display light source.
