Abstract:
1. An organic electroluminescence element, comprising: a light reflective electrode; a light transmissive electrode; an emission layer formed between the light reflective electrode and the light transmissive electrode; a low-refractive index layer having a refractive index at a maximum peak wavelength of an emission spectrum of light emitted from the emission layer lower than that of the emission layer, the low-refractive index layer being formed between the light reflective electrode and the emission layer; and a light extraction member for changing an exiting direction of the light emitted from the emission layer, the light extraction member being formed on the light transmissive electrode, wherein an optical path L between a maximum emission surface of the emission layer and a reflection surface of the light reflective electrode satisfies the following expression (1): in the expression (1), λ represents the maximum peak wavelength of the emission spectrum and φ represents a phase shift [deg] in the light reflective electrode.
