Claim 6:
7. The light-emitting device of claim 1, wherein:
at least one selected from R1 and R2 is —N(Q1)(Q2), a substituted or unsubstituted C1-C20 alkyl group, or a substituted or unsubstituted a carbazolyl group,
Q1 and Q2 are each independently selected from hydrogen; deuterium; —F; —Cl; —Br; —I; a hydroxyl group; a cyano group; a nitro group; an amidino group; a hydrazino group; a hydrazono group; a C1-C60 alkyl group; a C2-C60 alkenyl group; a C2-C60 alkynyl group; a C1-C60 alkoxy group; a C3-C10 cycloalkyl group; a C1-C10 heterocycloalkyl group; a C3-C10 cycloalkenyl group; a C1-C10 heterocycloalkenyl group; a C6-C60 aryl group; a C1-C60 heteroaryl group; a monovalent non-aromatic condensed polycyclic group; a monovalent non-aromatic condensed heteropolycyclic group; a C1-C60 alkyl group substituted with at least one selected from deuterium, —F, and a cyano group; a C6-C60 aryl group substituted with at least one selected from deuterium, —F, and a cyano group; a biphenyl group; and a terphenyl group,
adjacent Q1 and Q2 are optionally linked to each other to form a C2-C30 heterocyclic group unsubstituted or substituted with at least one R20a, and
R20a is the same as described in connection with R10a in claim 1.
