Claim 4:
5. The light emitting device according to claim 3, wherein said phosphorescent compound represented by the formula (1-A) is a phosphorescent compound represented by the following formula (1-A1), formula (1-A2), formula (1-A3) or formula (1-A4):, , wherein, M, n1, n2, R21A, R22A, R23A, R24A and A1-G1-A2 represent the same meaning as described above,
R11A, R12A and R13A each independently represent a hydrogen atom, an alkyl group, a cycloalkyl group, an alkoxy group, a cycloalkoxy group, an aryl group, an aryloxy group, a monovalent heterocyclic group, a substituted amino group or a halogen atom, and the foregoing groups optionally have a substituent, and when a plurality of R11A, R12A and R13A are present, they may be the same or different at each occurrence,
in the formula (1-A1), R11A and R21A may be combined together to form a ring together with atoms to which they are attached, in the formula (1-A2), R12A and R13A may be combined together to form a ring together with atoms to which they are attached, and in the formula (1-A3) and the formula (1-A4), R11A and R12A, R12A and R13A, and R11A and R21A may each be combined together to form a ring together with atoms to which they are attached.
