Abstract

An object of the present invention is to produce a phosphorescent organic electroluminescent element which can realize an electroluminescent peak in a deep blue region of not more than 440 nm which is important for completing a full-color display. The object can be attained by an organic electroluminescent element comprising a pair of electrodes, a luminescent layer or a plurality of thin organic compound layers including a luminescent layer between the pair of electrodes, characterized in that a phosphorescent electroluminescent peak appears at a wavelength of not more than 440 nm and further characterized in that the maximum phosphorescent electroluminescent peak appears in a deep blue region at a wavelength of not more than 440 nm, and the luminescent color is such that, in a Commision Internationale de l'Eclairage (CIE) color system, y-coordinate is less than 0.180.
