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. The light-emitting layer contains in the same layer, a white light emitting material A1 that presents an emission color at the coordinate A1 (x1, y1) in the CIE 1931 chromaticity coordinate system and a white light emitting material A2 that presents an emission color at the coordinate A2 (x2, y2) different from the coordinate A1(x1, y1) in the CIE 1931 chromaticity coordinate system. A distance LA1-A2 between the coordinates A1 (x1, y1) and A2 (x2, y2) in the CIE 1931 chromaticity coordinate system satisfies LA1-A2
