<P>PROBLEM TO BE SOLVED: To provide a method by which brightness performance of liquid crystal display is improved without changing design or die relative to brightness as regards a reflective film. <P>SOLUTION: In an optical film having a support, inorganic particle-containing coating is applied on at least one surface of the support. Inorganic particles to be used require no special condition when the particles have ultraviolet ray absorptivity, and as kinds of suitable inorganic particles, zinc oxide, silicon dioxide, titanium dioxide, aluminum oxide, calcium sulfate, barium sulfate, calcium carbonate, and those mixture are listed up. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
