1. 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, anda 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|<

    0.25, andwherein the refractive index n1 of the organic resin material into which the first fine particle is added and a refractive index n3 of the second fine particle satisfy a relationship n3

    n1>

    0.2.
