摘要： Provided is a light-emitting device including an anode, a light-emitting layer, an electron-transporting layer and a cathode. The electron-transporting layer contains at least one electron-transporting material whose LUMO level is −3.0 eV or more and at least one dopant material selected from the group consisting of a heterocyclic compound whose SOMO level is −2.2 to −1.5 eV and a derivative thereof. The LUMO level of the electron-transporting material is smaller than the SOMO level of the heterocyclic compound.
