Abstract:
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, a fine particle-containing layer positioned in the optical path of light emitted from the light emitting layer and adjacent to the transparent electrode and a reflection plate disposed on a surface of the fine particle-containing layer opposite to a surface thereof provided with the transparent electrode, an interlayer insulating layer disposed on a surface of the reflection plate opposite to the surface of the reflection plate that is adjacent to the fine particle-containing layer, and a passivation layer disposed on a surface of the interlayer insulating layer opposite to the surface of the interlayer insulating layer that is adjacent to the reflection plate, wherein the fine particle-containing layer comprises an organic resin material having a refractive index equal to or lower than the refractive index of the transparent electrode, and fine particles having a refractive index higher than the refractive index of the organic resin material and a weight average particle diameter of 0.5 μm to 5 μm, and the fine particle-containing layer has a thickness of 2 μm to 10 μm.
