WHITE FILM FOR BACKLIGHT REFLECTING PLATE AND BACKLIGHT USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a film for a backlight reflecting plate that does not have a wavy deformation or lifting of an edge, preferably a white film for the backlight reflecting plate that reduces possibility of mistaking the top and reverse sides of the white film for the backlight reflecting plate when it is assembled.

SOLUTION: The white film for the backlight reflecting plate is made of a polymer film of which thermal shrinkage is at least -0.2% and not more than 0.5% at 90°C in both the longitudinal direction and the width direction of the film.
