Title: (EN) REFLECTIVE FILM FOR EDGE-LIGHT-TYPE BACKLIGHT, AND LIQUID CRYSTAL DISPLAY BACKLIGHT USING SAME
(ZH) 边光型背光源用反射膜及使用其的液晶显示器用背光源
Abstract: front page image
(EN) Provided is a reflective film having excellent reduction of damage to the surface of the reflective film due to rubbing together of a light guide plate and the reflective film, and whereby uneven luminance of an edge-light-type liquid crystal backlight can be reduced. A reflective film for an edge-light-type backlight, having a particle-containing layer containing spherical particles on at least one side of a substrate film, and satisfying conditions (i) and (ii). (i): A compression-displacement curve of the spherical particles has at least two inflection points including a first inflection point and a second inflection point. (ii): The second inflection point in the compression-displacement curve is within a range of a displacement rate equal to or greater than 50% of the particle diameter.
(ZH) 本发明提供实现降低边光型液晶背光源的亮度不均,并且在降低由于导光板与反射膜互相摩擦而发生的反射膜表面损伤方面优异的反射膜。边光型背光源用反射膜,其在基材膜的至少一面上具备含有球状颗粒的含颗粒层,并且满足下述(i)及(ii)。(i)所述球状颗粒的压缩位移曲线具有第一拐点及第二拐点至少两个拐点;(ii)所述压缩位移曲线中,在粒径的50%以上的位移率范围内具有第二拐点。
