LIGHT-DIFFUSING FILM AND APPARATUS PROVIDED WITH THE SAME |
摘要 |
A light-diffusing film comprises a light-diffusing layer (e.g., an anisotropic light-diffusing layer), and the light-diffusing layer comprises a continuous phase comprising a polycarbonate-series resin (a polycarbonate-series resin having a number average molecular weight of 15000 to 25000) and a dispersed phase comprising a polypropylene-series resin (a metallocene-catalyzed polypropylene-series random copolymer). A transparent layer may be laminated on at least one side of the light-diffusing layer. The light-diffusing layer may substantially be free from a compatibilizing agent. In spite of a use of the polycarbonate-series resin, the dispersed phase can uniformly be formed. Therefore, the film is suitable for a member of a plane light source device or a display apparatus. The light-diffusing film inhibits a change in a light-diffusing characteristic even under a high temperature.
