ABSTRACT:
A white film for a reflecting structure for surface light sources, which contains voids inside it and has a light stabilizer-containing coating film formed on at least one surface of it, is aged little with time and its brightness lowers little even when used for a long time. The white film ensures good image quality of display screens for a long time, and it is favorable to reflecting sheets and reflectors in edge light-type and direct back light-type surface light sources for liquid crystal display screens.
