Claim 3:
4. 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-B1), formula (1-B2), formula (1-B3), formula (1-B4) or formula (1-B5):, , wherein,
M, n1, n2, R21A, R22A, R23A, R24A and A1-G1-A2 represent the same meaning as described above,
n11 and n21 each independently represent 1 or 2, however, n11+n21 is 3 when M is a ruthenium atom, a rhodium atom or an iridium atom, while n11+n21 is 2 when M is a palladium atom or a platinum atom,
R11B, R12B, R13B, R14B, R15B, R16B, R17B and R18B 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 R11B, R12B, R13B, R14B, R15B, R16B, R17B and R18B are present, they may be the same or different at each occurrence,
in the formula (1-B1), R11B and R12B, R12B and R13B, R13B and R14B, and R11B and R21A may each be combined together to form a ring together with atoms to which they are attached, in the formula (1-B2), R13B and R14B, R13B and R15B, R15B and R16B, R16B and R17B, R17B and R18B, and R18B and R21A may each be combined together to form a ring together with atoms to which they are attached, in the formula (1-B3), R11B and R12B, R12B and R13B, R13B and R14B, R11B and R21A, R13B and R15B, R15B and R16B, R16B and R17B, R17B and R18B, and R18B and R21A may each be combined together to form a ring together with atoms to which they are attached, in the formula (1-B4), R11B and R18B, R14B and R15B, R15B and R16B, R16B and R17B, R17B and R18B, and R11B and R21A may each be combined together to form a ring together with atoms to which they are attached, and in the formula (1-B5), R11B and R12B, R12B and R18B, R15B and R16B, R16B and R17B, R17B and R18B and R11B and R21A may each be combined together to form a ring together with atoms to which they are attached.
