MOIRE FRINGE SUPPRESSION FILM AND PRISM SHEET WITH MOIRE FRINGE SUPPRESSION FUNCTION

摘要

PROBLEM TO BE SOLVED: To provide a moire fringe suppression film which has a thin film thickness and a high moire fringe suppression effect and is capable of emitting uniform diffused light and is capable of maintaining high front brightness of a backlight and a liquid crystal display surface, when being used as a moire fringe suppression film for the backlight unit used in a liquid crystal display device.;SOLUTION: The moire fringe suppression film has a light diffusing layer wherein light diffusing particles are dispersed in a resin binder, on a light-transmissive base, and the light diffusing particles are aspherical porous particles and have a volume average particle size of ≤4 μm and a pore volume of 1.0 to 2.0 ml/g, and a center line average roughness Ra of a surface of the light diffusing layer is ≤0.5 μm.;COPYRIGHT: (C)2010,JPO&INPIT
