Abstract: Organic electroluminescent element capable of conveniently and precisely establishing the emission color of the element and capable of fine-adjusting the emission color in the white region. The organic electroluminescent element includes a pair of electrodes and a light-emitting layer provided between the electrodes and presents an emission color at the coordinate Ao (Xo, Yo) in the CIE 1931 chromaticity coordinate system.
