<p>A protective film for a polarizing membrane is provided which is prevented in light leakage generation, and excellent in moldability. The protective film comprises a polyamide resin, and is subjected to an orientation (e.g., a drawing) to have a retardation value of not less than 300 nm. The polyamide resin may comprise an alicyclic polyamide resin, e.g., a resin whose monomers comprise an alicyclic diamine and an aliphatic dicarboxylic acid. The polyamide resin may have microcrystallinity. The Abbe number of the polyamide resin may be not less than 40.</p> |
