Abstract
A white film including polymer film wherein both the thermal shrinkage rate in the longitudinal direction and that in the transverse direction of the film are not less than −0.2% and not more than 0.5% at 90° C., and a backlight for liquid crystal displays using such a white film. Since the white film hardly suffers from undulation or rise in its end portions, it is most suitable as a reflection film for backlights of liquid crystal displays. Since a backlight for liquid crystal displays using this white film can be used for a long time, it is applicable to liquid crystal displays of various electrical/electronic devices.
