1. A light-emitting diode comprising:
a first electrode;
a second electrode on the first electrode; and
at least one functional layer between the first electrode and the second electrode, the at least one functional layer comprising an amine compound represented by Formula 1:

OG Complex Work Unit Chemistry
wherein, in Formula 1,
X is O, S, SiRaRb, or NRc,
R1 to R18, Ra, Rb, and Rc are each independently a hydrogen atom, a deuterium atom, a halogen atom, a substituted or unsubstituted silyl group, a substituted or unsubstituted amine group, a substituted or unsubstituted alkyl group having 1 to 20 carbon atoms, a substituted or unsubstituted ring-forming aryl group having 6 to 30 carbon atoms, or a substituted or unsubstituted ring-forming heteroaryl group having 2 to 30 carbon atoms, and/or combined with an adjacent group to form a ring, and
at least one selected from among R1 to R18 is represented by Formula 2:

OG Complex Work Unit Chemistry
wherein, in Formula 2,
L is a direct linkage, a substituted or unsubstituted ring-forming arylene group having 6 to 30 carbon atoms, or a substituted or unsubstituted ring-forming heteroarylene group having 2 to 30 carbon atoms, and
Ar1 and Ar2 are each independently a substituted or unsubstituted ring-forming aryl group having 6 to 30 carbon atoms, or a substituted or unsubstituted ring-forming heteroaryl group having 2 to 30 carbon atoms, and
wherein when X is O, S, or NRc, then Ar1 and Ar2 are each independently a substituted or unsubstituted naphthyl group, a substituted or unsubstituted fluorenyl group, a substituted or unsubstituted carbazolyl group, a substituted or unsubstituted dibenzofuranyl group, or a substituted or unsubstituted dibenzothiophenyl group, provided that Ar1 and Ar2 are not a substituted or unsubstituted fluorenyl group at the same time.
