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 a light emitting layer. With regard to the first light emitting layer being the first closest light emitting layer to the light reflective electrode, the relation defined by following expression (2) is satisfied, ⁢ [ FORMULA ⁢ ⁢ 1 ] ϕ ⁡ ( λ m ) × λ m 4 ⁢ π + l + 0.1 2 ⁢ λ m ≤ n m ⁡ ( λ m ) × d m ≤ ϕ ⁡ ( λ m ) × λ m 4 ⁢ π + l + 0.5 2 ⁢ λ m ( 2 ) wherein, λm represents the weighted average emission wavelength, Ø(λm) represents the phase shift, nm(λm) represents the average refractive index of a medium filling a space between the light reflective electrode and the first light emitting layer, and dm represents the distance from the light reflective electrode to the first light emitting layer. m is equal to 1.1 is an integer equal to or more than 0.
