Beschreibung
Zusammenfassung:	The present invention relates to an electroluminescence device having high luminous efficiency (for example, external quantum efficiency) and high durability and causing little chromaticity shift after device deterioration. The present invention also relates to an organic electroluminescence device material comprising a substrate having thereon a pair of electrode and at least one organic layer between the electrodes, the organic layer containing a light emitting layer, wherein the light emitting layer contains a metal complex having a group represented by formula (I).
