Abstract:
1. An organic electroluminescence device comprising: a light transmissive electrode, a light reflective electrode, an organic luminescent layer disposed between said light transmissive electrode and said light reflective electrode, said organic luminescent layer including at least one light emissive layer that contains a light emitting material, a light transmissive substrate disposed on said light transmissive electrode away from said organic luminescent layer; and a light scattering region disposed on an outer surface of said light transmissive substrate, wherein at least one said light emissive layer of said organic luminescent layer has a luminescent point which is spaced from said light reflective electrode by a distance (d) defined by the following equation: and wherein λ is a wavelength of a specific light emitted from said light emissive layer, n is a refractive index of a layer disposed between the luminescent point of the light emissive layer and the light reflective electrode, with respect to the wavelength of λ, n n a is a value that satisfies a relation of “1.28<a≦−5.56×n wherein n n
