POLYCARBONATE RESIN FILM AND METHOD FOR PRODUCTION THEREOF

摘要

A polycarbonate resin film which has an average thickness of 10 to 150 µm, a thickness nonuniformity of 2 % or less, a retardation R (589) in the plane of the film measured at a wavelength of 589 nm of 12 nm or less, a retardation Rth(589) in the thickness direction of the film measured at a wavelength of 589 nm of 35 nm or less and is used for optical purposes.
