LIGHT-DIFFUSING FILM FOR DIRECT BACK LIGHT UNIT OF LCD

摘要

A light-diffusing sheet for a direct backlight unit of an LCD is provided to decrease blurring and increase a viewing angle of the LCD by mixing at least two organic particles with different refractive indexes on one surface of a substrate sheet. A light-diffusing sheet(1) for a direct backlight unit of an LCD(Liquid Crystal Display) includes a plastic substrate sheet(10), a light diffusion sheet(12), and an adhesion preventing layer(13). The plastic substrate sheet contains organic particles of 0.5 to 50 w% with respect to a binder resin of 100 w%. The light diffusion sheet is formed by mixing at least two optical particles with different refractive indexes on one surface of the substrate sheet. The adhesion preventing layer is formed by adding a conduction preventing material on a rear surface of the substrate sheet.
