A process for fabricating an organic electroluminescence device having at least a transparent electrode, an organic compound material layer including a light-emitting layer, and a metal electrode formed in turn on a transparent substrate. The organic compound material layer is demarcated by the light-emitting interface of the emitting layer into a transparent electrode side portion and a metal electrode side portion. The transparent electrode side portion of the organic compound material layer or the transparent electrode has an interface with a largest difference in the refractive indexes. The process has the steps of providing a transparent substrate on which a transparent electrode is formed; layering organic compound material layers in turn on the transparent electrode to form a transparent electrode side portion of organic compound material layers so as to have a film thickness such that an optical distance from the light-emitting interface to the interface with the largest difference in the refractive indexes is substantially equal to even multiples of one quarter of the wavelength; layering a light-emitting layer and other organic compound material layers in turn on the transparent electrode side portion to form a metal electrode side portion of organic compound material layer so as to have a film thickness such that an optical distance from the light-emitting interface to an interface bordering on the metal electrode is substantially equal to odd multiples of one quarter of the wavelength; and layering a metal electrode on the metal electrode side portion of the organic compound material layer. <IMAGE> |
