Patent ID: 8018145

Claim:
An organic electroluminescence display device comprising: an organic electroluminescence element which comprises a transparent electrode, a counter electrode, and an organic compound layer provided between the transparent electrode and the counter electrode, 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 n 1 of the organic resin material into which the first fine particle is added and an average refractive index n 2 of the organic compound layer satisfy a relationship |n 1 −n 2 |<0.25, and wherein the refractive index n 1 of the organic resin material into which the first fine particle is added and a refractive index n 3 of the second fine particle satisfy a relationship n 3 −n 1 >0.2.
