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.
