ORGANIC ELECTROLUMINESCENT ELEMENT, ILLUMINATION DEVICE, DISPLAY DEVICE, AND TRANSITION METAL COMPLEX

WIPO Patent Application WO/2018/186356

A1

A problem to be solved by the present invention is to provide, as a blue phosphorescence element, an organic electroluminescent element that has a high light emission efficiency, a low driving voltage, and excellent durability while having sufficiently short wave emitted light. In addition, another problem to be solved by the present invention is to provide an illumination device and a display device equipped with the organic electroluminescent element. Furthermore, another problem to be solved by the present invention is to provide a phosphorescent light-emitting transition metal complex that enables the foregoing to be realized, an organic electroluminescent element material that contains the phosphorescent light-emitting metal complex, and an organic electroluminescent element material composition. This organic electroluminescent element contains a phosphorescent light-emitting transition metal complex in at least one of organic layers including a light-emitting layer. The organic electroluminescent element is characterized in that the transition metal complex includes a ligand in which a plurality of aromatic rings are directly bonded to a transition metal serving as a center metal, and the ligand satisfies two specific requirements.
