METHOD FOR MANUFACTURING POLARIZER PROTECTIVE FILM AND POLARIZER PROTECTIVE FILM

摘要

PROBLEM TO BE SOLVED: To provide a polarizer protective film having excellent optical characteristics as well as high durability and strength, and has a light-diffusing function with high reliability.SOLUTION: A method for manufacturing a polarizer protective film having a light-diffusing function is provided, which includes steps of: melt-extruding a thermoplastic resin from a molding die into a sheet; and nipping and pressurizing the melt-extruded thermoplastic resin in a sheet state by a first roll having a concavo-convex pattern on a surface thereof and a second roll so as to form a concavo-convex pattern on one surface of the sheet.
