Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an optical film capable of being made thin and lightweight and exhibiting high luminance and high reflectance. SOLUTION: The optical film has a diffuse-reflective film (B) and a metallic reflective film (C). The metallic reflective film (C) is a laminated body formed by laminating a metallic reflection layer (C-2) on a substrate film (C-1). wherein the substrate film (C-1) is stretched in at least uniaxial direction and has ≤10 μm thickness. The optical film has luminance of 11,000 cd/m2or higher. COPYRIGHT: (C)2010,JPO&INPIT
