ABSTRACT:
A liquid crystal display unit using a back light uses a light guiding sheet to transfer to a liquid crystal display panel the light from a light source, and provides a liquid crystal display unit where a display of images is obtained with uniform brightness and high brightness. The light guiding sheet 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. This light guiding sheet is constructed so as to be employed in a back light.
