An organic electroluminescence device comprises a light transmissive substrate, a light scattering region which is disposed on the light transmissive substrate, and a light emissive layer having a luminescent point. The luminescent point is spaced from the light reflective electrode by a distance of d which satisfies the following equation: nd = a × λ 4 ⁢ ( 2 + ϕ π ) wherein ϕ = tan - 1 ⁢ { 2 ⁢ ( n 1 ⁢ k 2 - n 2 ⁢ k 1 ) n 1 2 - n 2 2 + k 1 2 - k 2 2 } . 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. n1 and k1 are respectively a refractive index and an attenuation coefficient of the layer disposed between the luminescent point of the light emissive layer and the light reflective electrode, and is in contact with said light reflective electrode, with respect to the wavelength of λ. n2 and k2 are respectively a refractive index and an attenuation coefficient of the light reflective electrode, with respect to the wavelength of λ. a is a value that satisfies a relation of “1.28
