Abstract:
A light-emitting element having high emission efficiency is provided. A light-emitting element having a low driving voltage is provided. A novel compound which can be used for a transport layer or as a host material or a light-emitting material of a light-emitting element is provided. A novel compound with a benzofuropyrimidine skeleton is provided. Also provided is a light-emitting element which includes the compound with the benzofuropyrimidine skeleton between a pair of electrodes.

Claim (Index 5):
A light-emitting device comprising:\n a first electrode; a light-emitting layer over the first electrode; an electron-transport layer over the light-emitting layer; and a second electrode, wherein the light-emitting layer comprises a first compound and a second compound and a light-emitting substance, wherein the electron-transport layer comprises a fourth compound, wherein at least one of the first compound and the fourth compound is represented by formula (G1): wherein A 1  represents a substituted or unsubstituted group having 6 to 100 carbon atoms, the group comprising at least one of a phenyl group, a fluorenyl group, a phenanthryl group, a triphenylenyl group, a dibenzothiophenyl group, a dibenzofuranyl group, a carbazolyl group, a benzimidazolyl group, a benzoxazolyl group, a benzthiazolyl group, and a triphenyl amine skeleton; and wherein R 1  to R 5  separately represent any one of hydrogen, an alkyl group having 1 to 6 carbon atoms, a substituted or unsubstituted monocyclic saturated hydrocarbon having 5 to 7 carbon atoms, a substituted or unsubstituted polycyclic saturated hydrocarbon having 7 to 10 carbon atoms, and a substituted or unsubstituted aryl group having 6 to 13 carbon atoms.
