Zusammenfassung:	Provided is a reflective film having a white base material layer, a metal thin film layer, and a protective layer, in that order, the white base material layer being arranged on the side of the surface to be used for reflection, wherein the reflective film is characterized in that when the reflective film is illuminated with light from the white base material layer side, Δb, represented in the following, is at least 1.0% but less than 4.0%, and the reflectance improvement (Δa/Δb) represented by the ratio of Δa, represented in the following, and the aforementioned Δb is 1.3-3.0, whereby the light-reflective film is provided with high levels of reflectance and durability suitable for a reflective member of a liquid crystal display, and has good chromaticity and low cost. Δa: difference of reflectance of light of 450 nm wavelength and light of 750 nm wavelength by white base material layer; Δb: difference of reflectance of light of 450 nm wavelength and light of 750 nm wavelength by reflective film
