Claim 15:
16. A diamine compound represented by Formula 1:, wherein in Formula 1,
Ar1 to Ar4 are each independently 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,
L1 is a direct linkage or a substituted or unsubstituted phenylene group,
L2 is a direct linkage, 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,
R1 and R2 are each independently a hydrogen atom, a deuterium atom, a halogen atom, a cyano group, a substituted or unsubstituted thiol group, a substituted or unsubstituted oxy group, a substituted or unsubstituted silyl 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,
x is an integer of 0 to 4,
y is an integer of 0 to 2, and
m and n are each independently an integer of 0 to 4, where m+n is not 0, and L1 and L2 are not both a direct linkage, and
wherein
i) when L2 is a naphthylene group,
the naphthylene group is represented by, where * represents a bindinq site to a neighboring atom, and

ii) when m is 1, n is 1, and L1 and L2 are each an unsubstituted phenylene group represented by, where * represents a bindinq site to a neighboring atom,
R1 and R2 are each independently a hydrogen atom, a deuterium atom, a substituted or unsubstituted alkyl group of 1 to 5 carbon atoms, an unsubstituted phenyl group, or a substituted or unsubstituted carbazole group.
