| titleOfInvention | Optical film and its manufacturing method |
| abstract | PROBLEM TO BE SOLVED: To provide a film capable of exhibiting a good effect as a three-dimensional retardation film and which can be easily produced, and a method for producing the same. An optical film containing a polymer and a solvent having crystalline properties, wherein the boiling point BpS of the solvent and the glass transition temperature TgP of the polymer satisfy the relationship of BpS ≧ TgP, and the solvent in the optical film. The content of is 0.001% by weight or more and 0.1% by weight or less, the surface roughness Ra of one or both surfaces of the optical film is 0.1 nm or more and 1000 nm or less, and the NZ coefficient is less than 1. , Optical film. A part of the solvent contained in the film (qA) by contacting the film with a solvent to impregnate the solvent to form a film (qA) and irradiating the film (qA) with an electron beam. A manufacturing method including a step of volatilizing. [Selection diagram] None |
