Abstract
An organic electroluminescent element is disclosed which comprises a light emission layer containing a fluorescent compound and a phosphorescent compound, the fluorescent compound having a nitrogen atom number to carbon atom number ratio in the molecule (N/C) of from 0 to 0.05, wherein the maximum emission wavelength of light emitted according to electroluminescence of the element is longer than the maximum fluorescence wavelength of the fluorescent compound.
Claims12
An organic electroluminescent element comprising a pair of electrodes and provided therebetween a light emission layer containing a first fluorescent compound and a phosphorescent compound, the first fluorescent compound having a nitrogen atom number to carbon atom number ratio in the molecule (N/C) of from more than 0 to 0.03, wherein the maximum emission wavelength of light emitted according to electroluminescence of the element is longer than the maximum fluorescence wavelength of the first fluorescent compound.
