LIGHT-SCATTERING FILM, AND DEVICE COMPRISING THE SAME |
摘要 |
Disclosed is a light-scattering film which has a light-scattering layer (e.g., an anisotropic light-scattering layer) composed of a continuous phase comprising a polycarbonate resin (a polycarbonate resin having a number average molecular weight of 15000 to 25000) and a dispersed phase comprising a polypropylene resin (a polypropylene-type random copolymer using a metallocene catalyst). A transparent layer may be laminated on at least one surface of the light-scattering layer. The light-scattering layer may not substantially contain a compatibilizing agent. In the light-scattering film, the dispersed layer can be formed homogeneously, in spite of a fact that a polycarbonate resin is used. Therefore, the light-scattering film is suitable as a member for a surface light source device or a display device. The light-scattering film exhibits a reduced change in light-scattering properties even when used under high-temperature conditions. |
