Abstract:
A light-emitting element having high luminous efficiency is provided. The light-emitting element includes a first organic compound, a second organic compound, and a third organic compound. The first organic compound and the second organic compound, in combination, are capable of forming an exciplex. The first organic compound is a phosphorescent compound and the third organic compound is a fluorescent compound. Light emitted from the light-emitting element includes light emitted from the third organic compound to which excitation energy is supplied from the exciplex formed by the first organic compound and the second organic compound.
