摘要： According to one embodiment, an organic electroluminescent light emitting device includes a transparent substrate, an intermediate layer, a first electrode, an organic light emitting layer, and a second electrode. The intermediate layer includes a plurality of fine particles and a flattened layer. The fine particles are adhered to a major surface of the transparent substrate. The flattened layer covers the fine particles and has a refractive index different from a refractive index of the fine particles. The flattened layer is transparent. The first electrode is provided on the intermediate layer. The first electrode is transparent. The organic light emitting layer is provided on the first electrode. The second electrode is provided on the organic light emitting layer.
