摘要：
Disclosed is a cellulose ester film which is suppressed in volatilization of components during film formation, while having high surface flatness, high durability after saponification and good adhesion to a polarizer. Also disclosed is a method for producing such a cellulose ester film by melt forming. Further disclosed are a polarizing plate having high light resistance and high durability, and a liquid crystal display having high image quality. Specifically disclosed is a cellulose ester film characterized by containing a cellulose ester, a compound represented by the general formula (1) below, and a compound represented by the general formula (2) below.
