Abstract
An organic EL device includes a luminescence layer containing a metal coordination compound represented by the following formula (1): LmML'n, wherein M denotes Ir, Pt, Rh or Pd; L denotes a bidentate ligand; L′ denotes a bidentate ligand different from L; m is an integer of 1, 2 or 3; and n is an integer of 0, 1 or 2 with the proviso that the sum of m and n is 2 or 3. The partial structure MLm is represented by formula (2) or formula (3) shown below, and the partial structure ML′n is represented by formula (4) or formula (5) shown below: wherein CyN1, CyN2 and CyN3 independently denote a substituted or unsubstituted cyclic group containing a nitrogen atom connected to M; CyN4 denotes a cyclic group containing 8-quinoline or its derivative having a nitrogen atom connected to M.
