Abstract:
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.

Claim (Index 7):
The light-emitting device according to any one of  claims 1  to  6 , wherein the electron-transporting material comprises a polymer compound having a constitutional unit represented by the formula (ET-1): wherein\n nE1 represents an integer of 1 or larger; \n Ar E1  represents an aromatic hydrocarbon group or a heterocyclic group, and these groups optionally have a substituent other than R E1 ; \n R E1  represents an alkyl group, a cycloalkyl group, an aryl group, an alkoxy group, a cycloalkoxy group, an aryloxy group, a monovalent heterocyclic group, or a group represented by the formula: \u2014R E2 (\u2014X 1 ) m1 ; when a plurality of R E1  are present, the plurality of R E1  are the same as or different from each other; \n X 1  represents a monovalent group containing a heteroatom; when a plurality of X 1  are present, the plurality of X 1  are the same as or different from each other; \n R E2  represents a direct bond or an (m1+1)-valent group; and \n m1 represents an integer of 1 or larger.
