1. An optical film comprising:
a polymer comprising a repeating unit A comprising a repeating unit represented by the following Chemical Formulas 1 to 3, or a combination thereof; and a repeating unit B derived from a monomer comprising an unsaturated bond copolymerizable with the repeating unit A, wherein the optical film has a short wavelength dispersion of an in-plane phase-difference value (Re) (450 nanometers/550 nanometers) ranging from about 0.81 to about 1.20, and a long wavelength dispersion of an in-plane phase-difference value (Re) (650 nanometers/550 nanometers) ranging from about 0.90 to about 1.18: wherein, in Chemical Formula 1, R1 to R6 are the same or different in each repeating unit and are each independently hydrogen, or a substituted or unsubstituted C1 to C10 aliphatic group, and R7 is the same or different in each repeating unit, and each is independently hydrogen, a substituted or unsubstituted C1 to C30 aliphatic group, a substituted or unsubstituted C3 to C30 alicyclic group, a substituted or unsubstituted C6 to C30 aromatic group, or a substituted or unsubstituted C2 to C30 heterocyclic group, wherein the alicyclic group, aromatic group, or heterocyclic group is present singularly; at least two of the alicyclic group, aromatic group, or heterocyclic group are linked to provide a condensed ring; or at least two of the alicyclic group, aromatic group, or heterocyclic group are linked via a single bond, —O—, —S—, —C(═O)—, —CH(OH)—, —S(═O)2—, —Si(CH3)2—, —(CH2)p— (wherein 1≦p≦10), —(CF2)q— (wherein 1≦q≦10), —C(CH3)2—, —C(CF3)2—, or —C(═O)NH—, wherein, in Chemical Formula 2, R8 to R13 are the same or different in each repeating unit and are each independently hydrogen, or a substituted or unsubstituted C1 to C10 aliphatic group, wherein, in Chemical Formula 3, R14 to R19 are the same or different in each repeating unit and are each independently hydrogen, or a substituted or unsubstituted C1 to C10 aliphatic group, and R20 and R21 are the same or different in each repeating unit and are each independently hydrogen, a substituted or unsubstituted C1 to C30 aliphatic group, a substituted or unsubstituted C3 to C30 alicyclic group, a substituted or unsubstituted C6 to C30 aromatic group, or a substituted or unsubstituted C2 to C30 heterocyclic group, wherein the alicyclic group, aromatic group, or heterocyclic group is present singularly; at least two of the alicyclic group, aromatic group, or heterocyclic group are linked to provide a condensed ring; or at least two of the alicyclic group, aromatic group, or heterocyclic group are linked via a single bond, —O—, —S—, —C(═O)—, —CH(OH)—, —S(═O)2—, —Si(CH3)2—, —(CH2)p— (wherein 1≦p≦10), —(CF2)q— (wherein 1≦q≦10), —C(CH3)2—, —C(CF3)2—, or —C(═O)NH—. |
