摘要：
The present invention provides a white organic electroluminescent element which can emits white light and is free from deviation of chromaticity. This organic electroluminescent element comprises a substrate and, provided on the substrate, at least an anode, a cathode, and a light emitting layer held between the anode and the cathode. This organic electroluminescent element is characterized in that the light emitting layer contains at least three types of light emitting materials different from each other in X max, and the absolute value of HOMO level of the light emitting material having the shortest wavelength is smaller than the absolute value of HOMO level of the other light emitting materials.
