1. An amine-based curing agent, comprising a compound represented by Chemical Formula 1:

OG Complex Work Unit Chemistry
wherein, in Chemical Formula 1,
R11, R12, R21, and R22 are each independently hydrogen, a halogen, a C1 to C20 alkyl group, a C1 to C20 heteroalkyl group, a C1 to C20 haloalkyl group, a C1 to C20 alkoxy group, or a C6 to C10 aryl group,
A1 is —CRa=CRb—, —N═CRc—, —N═N—, or —CRd=N—, wherein Ra, Rb, Rc, and Rd are each independently hydrogen, a C1 to C10 alkyl group, or a C1 to C10 haloalkyl group,
L11 and L12 are each independently —C(═O)O—, —OC(═O)—, —O—C(═O)O—, —C(═O)—, —CRe=CRf—C(═O)—, —S(═O)—, —CRg=N—, —NRhC(═O)O—, —C(═O)NRi—, or —OC(═O)NHS(═O)O—, wherein Re, Rf, Rg, Rh, and Ri are each independently hydrogen, a C1 to C10 alkyl group, or a C1 to C10 haloalkyl group,
Ar11 and Ar12 are each independently a substituted or unsubstituted C6 to C30 arylene group, C2 to C30 heteroarylene group, or a combination thereof, and
n1 and n2 are each independently an integer of greater than or equal to 2.
