a first electrode;
a second electrode on the first electrode; and
an emission layer between the first electrode and the second electrode, the emission layer comprising a compound represented by Formula 1:

OG Complex Work Unit Chemistry
in Formula 1,
X1 to X4 are each independently CRa,
L is a substituted or unsubstituted arylene group of 6 to 30 carbon atoms for forming a ring, or a substituted or unsubstituted heteroarylene group of 2 to 30 carbon atoms for forming a ring,
“n” is 1 or 2,
Ar is a substituted or unsubstituted aryl group of 6 to 15 carbon atoms for forming a ring, or represented by Formula 2:

OG Complex Work Unit Chemistry
in Formula 2,
Y is N or B,
Z is a direct linkage, O, S, NRd, or CReRf,
“b” and “c” are each independently an integer of 0 to 4, and
Rb to Rf are each independently a hydrogen atom, a deuterium atom, a halogen atom, a cyano group, a substituted or unsubstituted silyl group, a substituted or unsubstituted amine group, a substituted or unsubstituted alkyl group of 1 to 20 carbon atoms, a substituted or unsubstituted aryl group of 6 to 30 carbon atoms for forming a ring, or a substituted or unsubstituted heteroaryl group of 2 to 30 carbon atoms for forming a ring, and/or combined with an adjacent group to form a ring, and
Ra is a hydrogen atom, a deuterium atom, a halogen atom, a cyano group, a substituted or unsubstituted silyl group, a substituted or unsubstituted amine group, a substituted or unsubstituted alkyl group of 1 to 20 carbon atoms, a substituted or unsubstituted aryl group of 6 to 30 carbon atoms for forming a ring, or a substituted or unsubstituted heteroaryl group of 2 to 30 carbon atoms for forming a ring, and/or combined with an adjacent group to form a ring.
