Claim:
1. A monomer for a hardmask composition, the monomer being represented by the following Chemical Formula 1: wherein, in the above Chemical Formula 1, A and A′ are each independently a substituted or unsubstituted C6 to C60 aromatic cyclic group, a substituted or unsubstituted C5 to C60 aliphatic cyclic group, a substituted or unsubstituted C2 to C60 heteroaromatic cyclic group, a substituted or unsubstituted C2 to C60 heteroaliphatic cyclic group, or a combination thereof, wherein at least one hydrogen of A′ is substituted with a hydroxy group, X is a hydrogen atom, an oxygen atom, a halogen atom, a hydroxy group, a thionyl group, a thiol group, a cyano group, a substituted or unsubstituted amino group, a substituted or unsubstituted C1 to C30 alkyl group, a substituted or unsubstituted C1 to C20 alkylamine group, or a substituted or unsubstituted C1 to C30 alkoxy group, L is a single bond or a double bond, L′ is a single bond or a substituted or unsubstituted C1 to C6 alkylene group, and n is an integer ranging from 2 to 3, provided that: wherein the monomer is represented by the following Chemical Formula 1-1, 1-2, or 1-3: wherein, in the above Chemical Formulae 1-1, 1-2, and 1-3, L′ ma and mb are each independently an integer of 0 to 9, provided that ma+mb is at least 1, me and mf are each independently an integer of 0 to 9, provided that me+mf is at least 1, mc and md are each independently an integer of 0 to 11, provided that mc+md is at least 1, ma, mb, mc, md, me, and mf indicate the number of a substituted hydroxy group.
