Zusammenfassung:	PROBLEM TO BE SOLVED: To provide: a cellulose acylate film free from problems such as whitening, bleed-out, and sheet deterioration, not causing any problem such as sublimation or deposition etc. of additives to a manufacturing facility, being excellent in transparency and durability, having small optical anisotropy (Re, Rth) to be substantially optically isotropic, at low cost; and an optical compensation film, a polarizing plate, and a liquid crystal display manufactured by using the cellulose acylate film. SOLUTION: The cellulose acylate film contains a polyester polyol having three or more hydroxy groups in one molecule. There are provided the optical compensation film, the polarizing plate, and the liquid crystal display each using the cellulose acylate film. COPYRIGHT: (C)2010,JPO&INPIT
