摘要：
A cellulose acylate film comprising a polymer derived from at least a monomer represented by Formula 1 and a cellulose acylate having an acyl group of 3 or more carbon atoms, wherein a total number of carbon atoms contained in the acyl groups in one it of the cellulose acylate is larger than 6.0 and not larger than 7.5, wherein the total number of carbon atoms represents a sum of each product of a number of carbon atoms of each acyl group and a substitution degree of the acyl group, wherein the substitution degree represents an average number of 3 hydroxyl groups replaced with an acyl group in one glucose unit of the cellulose acylate:
