An object of the present invention is to provide a nano-particle light emitting material having a specific ligand and an electric field light emitting diode having high light emitting efficiency. The nano-particle light emitting material includes: a core portion formed of a nano-particle; and a shell portion formed of at least two kinds of ligands localized on a surface of the core portion, in which at least one kind of the ligands includes a hole transportable ligand, and at least one kind of the ligands includes an electron transportable ligand. |
