To obtain a white reflective film that is hard to warp and can ameliorate unevenness in the luminance even when used in such a manner as to be superimposed on a chassis having convex and concave portions for placing circuits and the like or used with an LED, and can prevent uneven close contact with a light guide plate and damage of the light guide plate, the white reflective film for edge-lit backlight is made to meets the requirements (i) to (iii):
(i) the stiffness is 2 to 10 mN·m;;
(ii) convex portions are formed on at least one surface (A) and the maximum height of the convex portion is 15 to 60 µm; and
(iii) the cushion rate at the side of a surface (B) opposite to the surface (A) is 12% or more. |
