The present invention relates to a cellulose acetate film, and more specifically to a cellulose acetate film and a method for producing same, the cellulose acetate film having superb durability by comprising one or more durability enhancers selected from compounds expressed by the chemical formula 1, and thus has low variation in the phase difference value even when exposed to high temperature and high humidity conditions for an extended period of time, and can improve viewing angle and contrast when used in a display apparatus as the phase difference value is high. |
