description The present invention addresses the problem of providing an organic electroluminescent light-emitting element which has a long operating lifespan. The present invention is a light-emitting layer material for an organic electroluminescent light-emitting element which contains a light-emitting compound and an organic metal compound, wherein the molecular weight of the organic metal compound is 1,200 or higher, the light-emitting compound is a specific compound, and the following relational expression (E-1) is satisfied. Relational expression (E-1) PkA < PkB (In formula (E-1), PkA is the maximum light emission wavelength (nm) of the organic metal compound, and PkB is the maximum light emission wavelength (nm) of the light-emitting compound.).
