1. A resist underlayer composition, comprising:
a polymer including a structural unit that is a reaction product of an isocyanurate compound and a compound having at least one reactive functional group, and
a solvent,
wherein:
the isocyanurate compound is represented by Chemical Formula 1:
in Chemical Formula 1, R1 to R3 are each independently a substituted or unsubstituted C1 to C30 alkyl group, a substituted or unsubstituted C1 to C30 heteroalkyl group, a substituted or unsubstituted C3 to C30 cycloalkyl group, a substituted or unsubstituted C2 to C30 heterocycloalkyl group, a substituted or unsubstituted C6 to C30 aryl group, or a substituted or unsubstituted C1 to C30 heteroaryl group, provided that at least one of R1 to R3 includes a thiol group substituent,
the compound having at least one reactive functional group is represented by one of the following Chemical Formula 2-1 to Chemical Formula 2-4:
