| Zusammenfassung: | The present invention relates to a film such as a protective film for a polarizing plate, an optically anisotropic film, and the like, which is employed for a liquid crystal display, and a polarizing plate and a liquid crystal display.
A film for a liquid crystal display. The film is a cellulose ester film with a thickness between 20 and 65 m and containing fine particles. The average diameter of fine particles is 0.05 to 3.0 m. The number of fine particles per 1,000 mis 5 to 500 in the cross-section perpendicular to the cellulose ester film in a region of a depth of not more than 10 m. |
