Claim 1:
2. The light emitting device according to claim 1, wherein said phosphorescent compound is a phosphorescent compound represented by the following formula (1):, , wherein,
M represents a ruthenium atom, a rhodium atom, a palladium atom, an iridium atom or a platinum atom,
n1 represents an integer of 1 or more, and n2 represents an integer of 0 or more, however, n1+n2 is 3 when M is a ruthenium atom, a rhodium atom, or an iridium atom, while n1+n2 is 2 when M is a palladium atom or a platinum atom,
E1 and E2 each independently represent a carbon atom or a nitrogen atom, however, at least one of E1 and E2 is a carbon atom, and when a plurality of E1 are present, they may be the same or different and when a plurality of E2 are present, they may be the same or different,
Ring L1 represents an aromatic hetero ring which optionally has a substituent, and when a plurality of the substituents are present, they may be combined together to form a ring together with atoms to which they are attached and when a plurality of Rings L1 are present, they may be the same or different,
Ring L2 represents an aromatic hydrocarbon ring or an aromatic hetero ring, and the foregoing rings optionally have a substituent, and when a plurality of the substituents are present, they may be combined together to form a ring together with atoms to which they are attached and when a plurality of Rings L2 are present, they may be the same or different,
the substituent which Ring L1 optionally has and the substituent which Ring L2 optionally has may be combined together to form a ring together with atoms to which they are attached,
A1-G1-A2 represents an anionic bidentate ligand, A1 and A2 each independently represent a carbon atom, an oxygen atom or a nitrogen atom, and these atoms may be ring constituent atoms, G1 represents a single bond or an atomic group constituting a bidentate ligand together with A1 and A2, and when a plurality of A1-G1-A2 are present, they may be the same or different.
