PROBLEM TO BE SOLVED: To provide a film that appropriately serves as a reflection member of a side light type backlight and has high luminance.SOLUTION: A light reflective film includes a reflection film 2 whose at least one side has a prism 1. The prism 1 satisfies conditions of (1) apexes of 60-135° and (2) distances between the apexes of 1-30 μm. The prism 1 has a refraction index of 1.35-1.60. The reflection film 2 is composed of at least 5 layers or more, having a structure in which two or more kinds of thermoplastic resin different in refraction indexes are aligned in a thickness direction, and is a multilayer laminated film having the thicknesses of all the layers of 0.1 μm or more and less than 0.6 μm. |
