Abstract

PURPOSE: To eliminate lighting unevenness owing to the light of lamp for nighttime lighting by distributing light scattering materials in such a manner that the incident light from the side face scatters evenly within a transparent substrate having light reflecting surface.
CONSTITUTION: Light scattering materials such as air, styrene, etc. are distributed in a transparent substrate 1 such as acrylic, glass or the like in such a manner that they become lower on the illuminating lamp side 4 and become higher on the opposite side in proportion to the distance from the light incident side face. A high reflectance material film 2 such as Al is provided on at least one surface of this substrate 1. Since the portions closer to the lamp 4 are less with the materials 3 in this way, more straightforward rays reach the materials 3 of further places and when the materials 3 are so distributed as to match the light emission mode of the lamp 4, the liquid crystal display in the nighttime is evenly illuminated.
