REFLECTION FILM FOR EDGE LIGHT TYPE BACKLIGHT AND BACKLIGHT FOR LIQUID CRYSTAL DISPLAYS USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a reflection film that reduces unevenness in luminance of an edge light type liquid crystal backlight, and excellently conceals foreign matter adhering to a reflection film surface.;SOLUTION: A reflection film for edge light type backlight has a resin layer containing a binder 3 and a particle 4 on a surface 2 of a base film. The particle 4 has a bottom parallel to the film surface, and the ratio between the bottom side length B of the particle 4 opposite the base film and the particle size D, B/D, is 0.2-1.5.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
