ABSTRACT:
It is an object of the present invention to provide a phosphorescence-emitting material that emits light in a wide visible light range from blue to red and has excellent color purity and reliability, etc. The present invention relates to a metal coordination compound represented by any one of Formulae (1) to (6),in-line-formulae description="In-line Formulae" end="lead"?B: >NR, >O, >S, >C═O, >SO2, >CR2in-line-formulae description="In-line Formulae" end="tail"?(in the formulae, M is Ir, Rh, Ru, Os, Pd, or Pt, and n is 2 or 3; when M is Ir, Rh, Ru, or Os and n is 2, another bidentate ligand further bonds to M; ring A is a cyclic compound containing a nitrogen atom bonded to M.
