Light guiding sheet

摘要

The present invention relates to a light guiding sheet which can be used in a back light of a liquid crystal display unit to transfer to the liquid crystal display panel the light from a light source, and aims at providing a liquid crystal display unit where the display of images can be obtained with uniform brightness and high brightness. A light guiding sheet 1 is formed by stacking two or more kinds of transparent amorphous layers different in refractive index at a predetermined angle with respect to a sheet surface 8. This light guiding sheet 1 is so constructed as to be employed in a back light.
