Abstract
A method for producing an organic electroluminescent element including a transparent substrate, a transparent electrode, an organic functional layer unit, and an electrode counter to the transparent electrode disposed in sequence, the method including: forming a preform of an element satisfying the following expression: ΔExy≥0.05, wherein 0° is an angle orthogonal to the transparent substrate and ΔExy represents a chromaticity difference of a reflected color measured at a tilted angle within a range of 0 to 80° with respect to the transparent substrate; and irradiating a specific region of the preform of the element with light.
