Abstract
The present disclosure relates to an organic electroluminescence element including: a substrate having a light transmissive property; a light diffusion layer; a light transmissive electrode; a light reflective electrode; and multiple light emitting layers spaced from each other. With regard to the m-th light emitting layer being the m-th closest light emitting layer to the light reflective electrode, relations defined by following expressions (2) and (3) are satisfied. In the following expressions, λrepresents the weighted average emission wavelength, Ø(λ) represents the phase shift, n(λ) represents the average refractive index of a medium filling a space between the light reflective electrode and the m-th light emitting layer, and drepresents the distance from the light reflective electrode to the m-th light emitting layer. l is an integer equal to or more than 0.
