OPTICAL FILM AND METHOD FOR PREPARING THE SAME

摘要

Provided are an optical film and a method for manufacturing the same. The method for manufacturing an optical film includes a step of: forming a stack film by attaching a polyvinvl alcohol film to at least one side of a base film; and elongating the stack film. The base film is copolymer including polyvinvl alcohol resin. 6 times tensile stress in water may be in a range of 0.8N/cm^2 to 2.4 N/cm^2.
