ORGANIC ELECTROLUMINESCENT ELEMENT, DISPLAY DEVICE, AND ILLUMINATION DEVICE

摘要

This invention addresses the problem of providing the following: an organic electroluminescent element that has a high luminous efficacy and excels in terms of drive voltage and stability; and a display device and an illumination device provided with said organic electroluminescent element. This organic electroluminescent element, which has at least an electron injection layer, an electron transport layer, and a light-emitting layer between an anode and a cathode, is characterized in that said electron injection layer contains an electride, the electron transport layer contains an organic compound that contains nitrogen atoms, at least one of said nitrogen atoms has an unshared electron pair that is not involved in aromaticity, and said unshared electron pair is not coordinated to a metal.
