Abstract
The present invention provides an anistropic diffusion sheet, which comprises an isotropic diffusion layer for isotropically diffusing the light incident from the light source portion by internal light scattering; and a plurality of reflectors which is disposed at an interval on the upper surface of the isotropic diffusion layer, so as to reflect the light isotropically diffused by the isotropic diffusion layer to the display panel, wherein the light, emitted from the light source portion and then becomes incident to the isotropic diffusion layer, is isotropically diffused through the isotropic diffusion layer, the light isotropically illuminated by the isoptropic diffusion layer is the reflected by the plurality of reflector to be anisotropically diffuse, and this anisotropically diffused light becomes incident to the liquid crystal display panel.
