| titleOfInvention | Method for producing sequential biaxially stretched retardation film and uniaxially stretched cast film used therefor |
| abstract | An object of the present invention is to provide excellent display quality such as contrast in a wide field of view in the front and perspective directions, with little retardation and optical axis variation in the plane of a retardation film formed from polycarbonate. The invention also provides a method for producing a retardation film that can be directly bonded to a polarizing plate capable of forming a liquid crystal display device for obtaining a uniform display in a plane that does not cause spotted light on a black display screen. . SOLUTION: A step of forming polycarbonate into a cast film by a solution cast film forming method, a longitudinal stretching step of stretching the cast film in the casting direction, and a transverse stretching step of stretching in a direction orthogonal to the casting direction. The in-plane film thickness variation of the uniaxially stretched uniaxially stretched cast film stretched in the longitudinal (or lateral) stretching process is 5 μm or less, and the uniaxial The uniaxially stretched cast film containing 0.1 to 1.0% by weight of the solvent in the stretched cast film is stretched in a direction substantially perpendicular to the stretching direction.
