摘要： A light reflective sheet is here disclosed which comprises a porous resin sheet and a protective layer laminated on at least one surface of the porous resin sheet; the porous resin sheet comprises a polyolefin resin and 100 to 300 parts by weight of a finely powdery inorganic filler with respect to 100 parts by weight of a polyolefin resin; the porous resin sheet is stretched at an area stretch magnification of 1.5 to 20 times; the light reflectance of the porous resin sheet at a wave length of 550 nm is 95% or more; and the stiffness of the light reflective sheet is at least 50 mm. A light reflector using the light reflective sheet is also disclosed. Preferably, the protective layer has a function as a UV light protective layer and/or a light leakage preventing auxiliary layer. The light reflective sheet is excellent in light resistant to ultraviolet light and the like, structure holding properties and light reflectivity, and so it is useful as a light reflective sheet for back light units of liquid crystal displays of word processors, personal computers, televisions and the like as well as lights, copying machines, projector system displays, facsimiles, electronic blackboards and the like.
摘要翻译：这里公开了一种光反射片，其包括多孔树脂片和层压在多孔树脂片的至少一个表面上的保护层; 相对于100重量份的聚烯烃树脂，多孔树脂片材包含聚烯烃树脂和100-300重量份的细粉末状无机填料; 多孔树脂片以1.5〜20倍的面积拉伸倍率拉伸; 波长为550nm的多孔树脂片的光反射率为95％以上; 光反射片的刚度至少为50mm。还公开了使用光反射片的光反射器。优选地，保护层具有作为UV光保护层和/或防漏光辅助层的功能。光反射片具有优异的耐紫外线等，结构保持性和光反射性，因此可用作文字处理器，个人计算机，电视机和液晶显示器的液晶显示器的背光单元的光反射片，照明，复印机，投影仪系统显示器，传真机，电子黑板等。
