Method for producing retardation film |
| abstract |
An object of the present invention is to provide a retardation film that exhibits a property (also referred to as reverse wavelength dispersion property) in which an absolute value of a photoelastic coefficient is small and a retardation value is decreased as the wavelength is shorter, using a polyvinyl acetal resin having a specific structure. Providing a manufacturing method. The method includes a step of forming a polymer film by molding a resin composition containing a polyvinyl acetal resin having a specific structure as a main component into a sheet by a melt extrusion method, and a step of stretching the polymer film. A method for producing a retardation film. [Selection figure] None |
