摘要

Optical compensation film based on cellulose acylate, comprises at least one compound with at least two rings, where one of these ring is an aromatic ring. Independent claims are also included for: (1) preparing the optical compensation film, comprising adding the compound with at least two rings to the mixture, which is used during the preparation of the compensation film; (2) preparing a polarizer plate, comprising applying the optical compensation film to a polarizer membrane or to a protective layer of the polarizer membrane, and preferably laminating; and (3) preparing a liquid crystal display, comprising applying the optical compensation film to the polarizer plate, and preferably laminating.
