OPTICAL FILMS WITH CONTROLLED SURFACE MORPHOLOGY AND THE METHOD OF MANUFACTURING THE SAME

摘要

Provided are an optical film for use in flat panel display (FPD) devices, and a method for manufacturing the same. Particularly, there is provided a method for imparting surface roughness to an optical film, which includes forming dented craters having a radius of curvature of 10 nm-100 µm on the surface of an optical film obtained by a solution casting process and forming a plateau between one crater and another crater. There is also provided an optical film obtained by the same method.
