| titleOfInvention | Manufacturing method of optical film |
| abstract | PROBLEM TO BE SOLVED: To provide a so-called foreign substance in a dope (resin solution) obtained by dissolving a resin film raw material in a solvent for a method for producing an optical film used in various display devices such as a liquid crystal display (LCD) or an organic EL (electroluminescence) display. An optical film manufacturing method capable of manufacturing an optical film with good contrast performance with high productivity by removing gel-like foreign matters under filtration conditions that easily remove water and ensuring retardation uniformity is provided. SOLUTION: A method for producing an optical film by a solution casting film forming method, wherein a dope is filtered at a boiling point at 1 atm of a main solvent of the main solvent at a temperature of 5 ° C. or more to thereby remove a gel-like foreign substance in the dope. The dope flow rate during removal is 10-80 kg / (hr · m 2 ), and then the dope after filtration is cast on a support, and the web formed on the support is further removed. After peeling, the web is stretched 1.1 to 2.0 times in the width direction. [Selection figure] None |
