A white reflective film for edge-lit backlight which meets the requirements (i) to (iii): (i) the stiffness is 2 to 10 mN·m as measured by JIS P8125, with measurements being made three times in each of both the directions of the reflective surface side and the non-reflective surface side of the white reflective film, and an average of the measurements being designated as stiffness; (ii) convex portions are formed on at least one surface of a base white film by coating with a coating liquid comprising a binder resin, spherical particles and a solvent, and the maximum height of the convex portion is 15 to 60 μm; and (iii) the cushion rate at the side of a surface opposite to the surface is 12% or more, with the cushion rate being a value measured by the following method: (a) a seat of 10 g is mounted on the upper part of a spindle of a dial gage and brought down onto a sample set on a measurement table by lifting the spindle in a test environment of 23°C and 50% RH, at this time, the non-reflective surface is situated at the spindle side, (b) a weight of 50 g is placed on the seat, the thickness is read after 5 seconds, and this value is taken as "a", (c) the weight on the seat is replaced by a weight of 500 g, the thickness is read after 5 seconds, this value is taken as "b", and a value determined by the following formula is designated as cushion rate "c": cushion rate c % = 100 × a − b / a.
