Abstract: 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.

Abstract: PURPOSE: To provide a liquid crystal display device with which image display having uniform brightness and high luminance is obtainable as a liquid crystal display device formed by using a back light for which a light transmission sheet to transmit the light from a light source to a liquid crystal display panel is used. CONSTITUTION: The light transmission sheet 1 is formed by laminating >=2 kinds of transparent amorphous layers varying in refractive index at prescribed angles with the sheet surface 8. The light transmission sheet 1 is so constituted as to be used for the back light.
