Cellulose resin film, method for producing a cellulose resin film, an antireflection film, a polarizing plate and a liquid crystal display device

An object of the present invention, while a wide, provides a cellulose-based resin film breakage is greatly reduced in the stretching step and a manufacturing method thereof, and an antireflection film using the same, a polarizing plate and a liquid crystal display device. Method for producing a cellulose resin film after peeling the web formed by casting a cellulose resin liquid on the support from the support, while the width grasping both ends of the web in the first width gripping step dried once, eliminating the width grip further provides a method for producing a cellulose resin film is stretched in the width direction at both ends with second width gripping step, after the first width grasping step, eliminating width grip characterized in that the two ends of the webs having a heat treatment step of heating by the heating roll.
