CELLULOSE ACYLATE OPTICAL FILM, METHOD FOR PRODUCING SAME, POLARIZING PLATE USING SAME, AND LIQUID CRYSTAL DISPLAY

摘要

Disclosed is a cellulose acylate optical film characterized by mainly composed of a cellulose acylate containing at least one polymer derived from a monomer represented by a specific general formula, having an acyl group with three or more carbon atoms, and having a total number of carbon atoms in acyl groups (the sum of each product of the substitution degree of each acyl group in the cellulose acylate and the number of carbon atoms in the acyl group) of more than 6.0 but not more than 7.5.
