Abstract
The present invention is to provide an iridium complex compound, which is soluble in an organic solvent, which can be stored for long periods without reprecipitation thereof and which secures a low driving voltage and a high luminescent efficiency of an organic electroluminescent element produced using the compound, to provide an organic electroluminescent element containing the compound and to provide a display and a lighting using the organic electroluminescent element. The present invention relates to the iridium complex compound having a specific chemical structure. Further, the invention also relates to the organic electroluminescent element produced using the compound, which requires a low operating voltage and has a long operating lifetime.
