Abstract

See full text

Organic electroluminescent element capable of conveniently and precisely establishing the emission color of the element. 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 CIE 1931 chromaticity coordinate system. The light-emitting layer contains in the same layer, a light emitting material A1 that presents an emission color at the coordinate A1 (x1, y1) in the CIE 1931 chromaticity coordinate system and a light emitting material A2 that presents an emission color at the coordinate A2 (x2, y2) in the CIE 1931 chromaticity coordinate system; a distance LAo-A1 between the coordinates Ao (Xo, Yo) and A1 (x1, y1) in the CIE 1931 chromaticity coordinate system satisfies LAo-A1≦0.20; and a distance LA1-A2 between the coordinates A1 (x1, y1) and A2 (x2, y2) in the CIE 1931 chromaticity coordinate system satisfies 0.13≦LA1-A2≦0.35 s.
