Abstract
A surface light source unit () includes a light source (), a light guide plate (), a reflective plate () and a diffusing plate (). The light guide plate includes a light incidence surface () adjacent to the light source for receiving light beams, an emission surface () for emitting the light beams, a light reflection surface () opposite to the emission surface and a plurality of diffusion dots () formed on the light reflection surface. The diffusion dots contain a plurality of light scattering particles () having substantially global surfaces. The surface light source unit provides high uniform illumination for a liquid crystal display panel.
