1. A polarizing film comprising
a polyolefin and a dichroic dye represented by the Chemical Formula 1, wherein a solubility parameter difference between the polyolefin and the dichroic dye is less than 7.4: wherein, in Chemical Formula 1, Ar1 to Ar3 are each independently a substituted or unsubstituted C6 to C15 arylene group, R1 is a substituted or unsubstituted C1 to C30 aliphatic group, a substituted or unsubstituted C3 to C8 cycloaliphatic group, a substituted or unsubstituted C6 to C30 aromatic group, a substituted or unsubstituted C1 to C30 hetero aliphatic group, a substituted or unsubstituted C1 to C30 hetero aromatic group, or a combination thereof, R2 is hydrogen, a substituted or unsubstituted C1 to C30 aliphatic group, a substituted or unsubstituted C3 to C8 cycloaliphatic group, a substituted or unsubstituted C6 to C30 aromatic group, a substituted or unsubstituted C1 to C30 hetero aliphatic group, a substituted or unsubstituted C1 to C30 hetero aromatic group, a substituted or unsubstituted amino group, —NR3R4, or a combination thereof, wherein R3 and R4 are each independently hydrogen, a substituted or unsubstituted C1 to C10 alkyl group, or are linked to each other to form a ring, and n and m are independently 0 or 1. |
