摘要：
A light-emitting element which at least includes a monomolecular layer including a luminescent center material with a fluorescent light-emitting property, and a monomolecular layer including a host material with a carrier (electron or hole)-transport property and a band gap larger than a band gap (note that a band gap refers to the energy difference between a HOMO level and a LUMO level) of the luminescent center material, between a pair of electrodes, in which the monomolecular layer including the host material and the monomolecular layer including the luminescent center material share the same interface, is provided.
