    摘要： An object is to provide an optical film in which retardation variation is less even after a long period of duration of use, to provide an optical compensating film in which transparency and flatness are not deteriorated in a stretching process by using the foregoing film as a support, and to provide a polarizing plate and a liquid crystal display exhibiting reduced visibility variation caused by heat generation of an optical LED backlight, and excellent color reproducibility. Disclosed is a manufacturing method of an optical film formed by melt-casting a composition containing a cellulose resin and a plasticizer, wherein the cellulose resin has a residual sulfuric acid content of 0.1-50 ppm, and the composition contains a polymer having a weight average molecular weight of 500-30000 prepared via polymerization of ethylenic unsaturated monomers, or an acrylic polymer having a weight average molecular weight of 500-30000.
