COMPOSITION FOR LIGHT-EMITTING DEVICE, LIGHT-EMITTING DEVICE, LIGHT-EMITTING APPARATUS, ELECTRONIC DEVICE, AND LIGHTING DEVICE

A composition for a light-emitting device is provided. The composition is formed by mixing a first organic compound having a benzofuropyrimidine skeleton, and a second organic compound represented by General Formula (Q1):R1 to R14 each independently represent hydrogen, an alkyl group having 1 to 6 carbon atoms, a substituted or unsubstituted monocyclic saturated hydrocarbon having 5 to 7 carbon atoms in a ring, a substituted or unsubstituted polycyclic saturated hydrocarbon having 7 to 10 carbon atoms in a ring, a substituted or unsubstituted aryl group having 6 to 13 carbon atoms in a ring, or a substituted or unsubstituted heteroaryl group having 3 to 20 carbon atoms in a ring. Furthermore, β1 and β2 each represent any of an unsubstituted β-naphthyl group, an unsubstituted biphenyl group, and an unsubstituted terphenyl group, and at least one of β1 and β2 is an unsubstituted β-naphthyl group.
