LIGHT-DIFFUSING SHEET FOR BACK LIGHT UNIT OF LCD

摘要

A light diffusion sheet for an LCD backlight unit is provided to improve perpendicularity luminance by using transparent resin particles having a diameter of 5 to 60 micro meter. A light diffusion sheet(10) for an LCD backlight unit comprises a transparent polyester substrate film(1) and a light diffusing layer. The light diffusion sheet is formed by coating coating-solutions, including transparent binder resin(3) and transparent resin particle(2), in at least one side of the substrate film. The transparent resin particle is a silicon particle or a particle in which silicon is coated on the surface of transparent resin particle. The resin particle has a particle diameter of 5 to 60 micro meter. The transparent resin particle comprises one inorganic particle selected from a group configured with synthetic silica, glass bead and diamond together with the silicon particle or the particle where the silicon is coated in the surface of the transparent resin particle.
