LIGHT DIFFUSION SHEET FOR A BACKLIGHT UNIT OF A LIQUID CRYSTAL DISPLAY DEVICE AND A MANUFACTURING METHOD THEREOF, CAPABLE OF FORMING A LIGHT DIFFUSION LAYER BY PARTIALLY BURYING A LIGHT DIFFUSION PARTICLE WITH A PROPER PARTICLE DIAMETER

摘要

PURPOSE: A light diffusion sheet for a backlight unit of a liquid crystal display device is provide to improve high brightness by improving the shape of a lens surface and lens density.;CONSTITUTION: A base sheet(1) is made of a synthetic resin. A binder resin(3) is formed on one side of the base sheet. A light diffusion layer is made of light diffusion particles(2). The light diffusion particle forms the lens surface. The binder resin is removed on the upper side of the light diffusion particle exposed on the surface to improve vertical brightness.;COPYRIGHT KIPO 2010
