PROBLEM TO BE SOLVED: To provide an organic luminescent composition which can give an electroluminescent element capable of emitting a blue light, having high luminous intensity and luminous efficiency, and excellent in durability, and which can easily form an organic material layer by a wet process. SOLUTION: The luminescent composition contains a specified iridium complex compound and a polymeric substance having hole transfer capability. It is desirable that the polymeric substance having hole transfer capability comprises a copolymer consisting of 50-99 mol% of structural units derived from a hole transfer monomer and 1-50 mol% of structural units derived from an electron transfer monomer, or it comprises a polymer composition consisting of a hole transfer polymer obtained by polymerizing a hole transfer monomer, and an electron transfer polymer obtained by polymerizing an electron transfer monomer at a molar ratio, in terms of monomers, of the hole transfer polymer to the electron transfer polymer of (50:50) to (99:1).
