Title:
IRIDIUM COMPLEX COMPOUND, SOLUTION COMPOSITION CONTAINING IRIDIUM COMPLEX COMPOUND, ORGANIC ELECTROLUMINESCENT ELEMENT, DISPLAY DEVICE, AND LIGHTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/105615
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: an iridium complex compound which is soluble in an organic solvent, can be stored for a long period of time without suffering from re-precipitation of the compound, and enables the production of an organic electroluminescent element that has low driving voltage and high luminous efficiency; an organic electroluminescent element which uses the compound; and a display device and a lighting device, each of which uses the organic electroluminescent element. The present invention relates to an iridium complex compound which has a specific chemical structure. The present invention also relates to an organic electroluminescent element which is produced using the compound and has low driving voltage and long service life.
