  • Publication number: 20150158987
    Abstract: Provided is a cellulose acylate film that barely causes display unevenness when the cellulose acylate film is incorporated into a liquid crystal display. The cellulose acylate film includes a cellulose acylate having a total degree of acyl substitution of 2.0 to 2.35 and having a thickness of 20 to 39 ?m. The film includes (Component 1) a sugar ester compound having one to six of at least one kind of pyranose and furanose structures, the OH groups of the pyranose and furanose structures being partially esterified with an aromatic organic acid (wherein the ratio A/B of the esterified rate A of the OH groups in the sugar ester compound to the acylated rate B of the OH groups in the cellulose acylate is 0.55 to 0.95); and (Component 2) an aromatic ester oligomer.
