Abstract:
The present invention provides an organic electroluminescence display device including an organic electroluminescence element which includes a transparent electrode, a counter electrode, and an organic compound layer provided between these electrodes, the organic compound layer including a light emitting layer, and a fine particle containing layer positioned in the optical path of light emitted from the light emitting layer, wherein the fine particle containing layer contains an organic resin material, a first fine particle, and a second fine particle having a weight average particle diameter greater than that of the first fine particle, wherein a refractive index n1 of the organic resin material into which the first fine particle is added and an average refractive index n2 of the organic compound layer satisfy a relationship |n1−n2| 0.2.
