Abstract:
A beam direction control element has transparent areas and light absorption areas alternately arranged on a surface of a substrate, wherein the light absorption areas function as a louver for controlling the direction of a beam of light. The beam direction control element is manufactured by disposing an optically transparent material on a first transparent substrate to form transparent ridges which constitute the transparent areas, filling curable and photo-absorptive fluid in gaps between the transparent ridges, and then curing the fluid to form the light absorption areas.
