Abstract:
1. An organic electroluminescence device comprising: a first electrode; a second electrode located on a light extraction side and comprising a metal film; an organic compound layer provided between the first electrode and the second electrode and including an emission layer; and a first inorganic protective layer in direct contact with the second electrode, a coverage layer made of a resin, which is provided on the first inorganic protective layer, a difference between a refractive index of the first inorganic protective layer and that of the coverage layer is 0.4 or more, wherein a thickness of the first inorganic protective layer satisfies: where d indicates the thickness of the first inorganic protective layer, n indicates a refractive index of the first inorganic protective layer, λ indicates a maximum peak wavelength of a spectrum of light emitted from the organic electroluminescence device, and m indicates a natural number, and wherein a distance between the first electrode and the second electrode satisfies: where D indicates an optical distance between the first electrode and the second electrode, λ indicates an electroluminescence light emitting wavelength, φ1indicates a phase shift amount on the first electrode, φ2 indicates a phase shift amount on the second electrode, and N indicates an integer.
