Abstract
Disclosed is a method of manufacturing an optical film, in which a transparent cycloolefin copolymer (COC) material is used as a raw material thereof and solved in a solvent to constitute a solution for forming the optical film. The thus formed optical film may have optical characteristics similar to those of prior-art optical film. Therefore, a retardation film or a protective film may be manufactured using cheaper and more accessible raw materials.
