ORGANIC ELECTROLUMINESCENT ELEMENT, ILLUMINATOR, AND DISPLAY DEVICE

WIPO Patent Application WO/2014/034584

A1

The present invention addresses the problems of providing: an organic electroluminescent element which works at a low voltage, has a high luminescent efficiency and excellent durability, and is highly effective in preventing the generation of dark spots or luminescence unevenness; and an illuminator and a display device which are equipped with the organic electroluminescent element. This organic electroluminescent element comprises an anode and a cathode and, sandwiched therebetween, one or more organic layers including a luminescent layer, and is characterized in that at least one of the organic layers contains a phosphorescent organometallic complex in which a ligand represented by general formula (1) or general formula (2) has coordinated to a metal atom.
