<p><P>PROBLEM TO BE SOLVED: To provide an organic electroluminescent element which has high light emission efficiency and an excellent emission lifetime, and suffers less luminous color aging, and preferably has a film formed by wet deposition, and which is driven by a lower voltage, and is arranged so that dark spots are reduced, and the occurrence of the unevenness of luminance in light emission is suppressed, and to provide an illuminating device with the organic electroluminescent element. <P>SOLUTION: The organic electroluminescent element comprises: an anode; a cathode; and an organic layer composed of a single layer or multiple layers which has a light-emitting layer. In the organic electroluminescent element, the organic layer is held between the anode and the cathode. The organic layer has at least one layer which includes a phosphorescent organic metal complex having, as ligand, at least one of phenyl-imidazole-based compounds expressed by a certain general structural formula. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
