Claims25
A polarizing film comprising:
- a melt-elongated film comprising
- a polyolefin and
- a dichroic dye represented by Chemical Formula 1:
- wherein, in Chemical Formula 1,
- X is a substituted or unsubstituted C3 to C20 alkyl group or a substituted or unsubstituted C3 to C20 alkoxy group, which is attached at position 6 or 7 of a terminal naphthalene group,
- Ra is a halogen, a substituted or unsubstituted C1 to C5 alkyl group, or a substituted or unsubstituted C1 to C5 alkoxy group,
- Rb to Rd are hydrogen, a halogen, a substituted or unsubstituted C1 to C5 alkyl group, or a substituted or unsubstituted C1 to C5 alkoxy group,
- p is an integer of 1 to 3,
- q, r, and s are each independently an integer of 0 to 3,
- R1 and R2 are each independently hydrogen or a substituted or unsubstituted C1 to C10 alkyl group, which are optionally linked to each other to form a ring, and
- a first azo group is attached at position 1, 2, or 3 of the terminal naphthalene group.
