| titleOfInvention | Manufacturing method of optical film |
| abstract | A method of manufacturing an optical film having birefringence that can be used as a protective film for a polarizing plate of a liquid crystal display device (LCD), etc. Even when a wide belt support is used for film production, there is little meandering and stable. It is an object of the present invention to provide a method capable of maintaining stable conveyance and maintaining high productivity without causing poor drying at the end of a cast film (web) and deterioration in flatness of the film. In the production of an optical film by the solution casting method, the width of the belt support is 1.8 m or more, and the width (We) is 2 to 25% of the entire width (W) of the belt support from the left and right side edges. The thickness (Te) of the left and right end portions is 5 to 20% thinner than the thickness (T) of other portions including the width center portion of the belt support. Alternatively, the longitudinal elastic modulus (Ee) of the left and right end portions of the belt support is 5 to 20% smaller than the longitudinal elastic modulus (E) of other portions including the width center portion of the belt support. |
