Disclosed is a cellulose ester film for optical use which contains an ultraviolet absorbent and hardly suffers from retardation fluctuations. The cellulose ester film is excellent in spectral absorption property as an optical film. In addition, the cellulose ester film is free from coloration and has excellent transparency, which having sufficient ultraviolet absorption and excellent long-term light resistance. Also disclosed are a polarizing plate and liquid crystal display wherein high contrast is maintained by using such a cellulose ester film for optical use. Specifically disclosed is a cellulose ester film for optical use which is characterized by containing at least one compound represented by one of the general formulae 1-3. Also specifically disclosed are a polarizing plate and liquid crystal display using such a cellulose ester film for optical use.
摘要:
A composition for melt casting film formation that excels in not only uniformity of retardation being an optical characteristic, especially uniformity of retardation in the direction of film width, but also contrast; and relevant thereto, an optical film, process for producing the optical film, polarization plate and liquid crystal display apparatus. Accordingly, there is provided a composition for melt casting film formation containing a cellulose ester in an amount of 50 mass % or more, characterized in that the free acid content of the composition is 50 ppm or less.
