Cellulose ester film, polarizing plate and liquid crystal display

摘要

An optical film manufactured by stretching a cellulose ester comprising needle-shaped particles and an additive selected from the group consisting of a polyester, a polyalcohol ester, a polycarboxylic acid ester and a polymer obtained by polymerizing an ethylenically unsaturated monomer, wherein the needle-shaped particles exhibit negative birefringency in a stretching direction of the optical film.
