1. An organic layer composition, comprising:
a polymer that includes a substituted or unsubstituted fluorene structure, an additive represented by Chemical Formula 1, and a solvent: wherein, in Chemical Formula 1, k, m, and n are each independently 0 or 1, and a sum of k, m, and n is 2 or 3, when k+m+n=3, X is CH or nitrogen (N), when k+m+n=2, X is a direct bond, —(CqH2q)—, —(CtRw2t)—, oxygen (O), sulfur (S), or —S(O2)—, q and t being each independently an integer of 1 to 5, and Rw being a substituted or unsubstituted C1 to C20 alkyl group, a substituted or unsubstituted C6 to C30 aryl group, a substituted or unsubstituted C3 to C30 cycloalkenyl group, a substituted or unsubstituted C1 to C20 alkylamine group, a substituted or unsubstituted C7 to C30 arylalkyl group, a C1 to C20 heteroalkyl group, a substituted or unsubstituted C2 to C30 heterocycloalkyl group, a substituted or unsubstituted C2 to C30 heteroaryl group, a substituted or unsubstituted C1 to C4 alkyl ether group, a substituted or unsubstituted C7 to C20 arylalkylene ether group, a substituted or unsubstituted C1 to C30 haloalkyl group, a substituted or unsubstituted C2 to C20 alkenyl group, or a combination thereof, and R, R′, and R″ are each independently hydrogen, a hydroxy group, a substituted or unsubstituted C3 to C30 monovalent cyclic group, a substituted or unsubstituted C1 to C30 monovalent linear group, or a combination thereof. |
