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 6):
The light-emitting device according to  claim 5 , wherein\n the heterocyclic compound is a compound represented by the formula (2-A), and the derivative is a compound represented by the formula (2-B) or the formula (2-C): wherein\n R 4 , R 5  and X \u2212  are the same as above; \n R 2  represents an alkyl group, a cycloalkyl group, an aryl group, an alkoxy group, a cycloalkoxy group, an aryloxy group, an alkylsulfenyl group, a cycloalkylsulfenyl group, an arylsulfenyl group, a monovalent heterocyclic group, a halogen atom or a disubstituted amino group; \u2014CH 2 \u2014 in these groups is optionally substituted by an oxygen atom, a sulfur atom, \u2014NR 5 \u2014 or \u2014C(\u2550O)O\u2014, and a portion or the whole of hydrogen atoms in these groups is optionally replaced with a halogen atom, provided that adjacent two \u2014CH 2 \u2014 are not substituted at the same time; in the case where m is 2 or larger, a plurality of R 2  are the same as or different from each other; adjacent R 2  are optionally bonded to each other to form a ring; \n R 9  represents an alkyl group, a cycloalkyl group, an aryl group, an alkoxy group, a cycloalkoxy group, an aryloxy group, an alkylsulfenyl group, a cycloalkylsulfenyl group, an arylsulfenyl group, a monovalent heterocyclic group, a halogen atom or a disubstituted amino group; \u2014CH 2 \u2014 in these groups is optionally substituted by an oxygen atom, a sulfur atom, \u2014NR 5 \u2014 or \u2014C(\u2550O)O\u2014, and a portion or the whole of hydrogen atoms in these groups is optionally replaced with a halogen atom, provided that adjacent two \u2014CH 2 \u2014 are not substituted at the same time; in the case where n is 2 or larger, a plurality of R 9  are the same as or different from each other; adjacent R 9  are optionally bonded to each other to form a ring; \n m represents an integer of 0 to 5; \n n represents an integer of 0 to 4; and \n m+n is 2 or larger.
