Abstract
A white reflective film for an edge light backlight improves the luminance and unevenness therein, avoids uneven close contact with, and scraping of, the light guide plate, and minimizes the crushing of convexes formed on at least one side, even in cases where the reflective film is laid directly over a corrugated chassis designed to house circuitry or the reflective film is used in combination with LEDs. The film satisfies (i) to (iii): (i) a stiffness of 2 to 10 mN·m; (ii) convexes have been formed on at least one face (A), and their maximum height is 5 to 60 μm; (iii) the convexes contain an aromatic polyester.
