Abstract: A microlouver has, as a basic unit, a light-controlling layer in which a light-absorbing layer and a transparent layer are laminated together, and a plurality of basic units L and S comprising a plurality of types of light-controlling layers having different layer thicknesses or optical constants, disposed in the direction of the layer thickness of the basic units. The array mode of the basic units L and S is determined based on a random number or a sequence-generating rule. For this reason, the microlouver has a large number of frequency components in terms of spatial frequency, and moire fringes that have a specific period and are normally caused by the interference with other optical elements are therefore prevented from occurring.

Abstract: A microlouver includes a periodic structure in which a transparent layer and a light absorption layer are alternately disposed with a constant, repetitive period. The range of the exit direction of a light beam passing through the transparent layer is restricted by the light absorption layer. The periodic structure includes a periodic structure portion divided in the direction that intersects the direction in which the transparent layer and the light absorption layer are repeatedly disposed. In the periodic structure portion, between the periodic structures adjacent to each other, there is a difference of 180 degree in the phase of spatial frequency of each periodic structure.

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.

Abstract: To provide a sight controllable display device that is capable of switching a regular display and a concealed display easily. A display panel and a modulator are disposed between two polarizing plates. The display panel performs a regular display drive. Meanwhile, the modulator drives to operate at a speed faster than twice the speed of the display panel and modulate the display image of the display panel. When displaying an image that is desired to be concealed, the period where the modulator is not in action is selected and viewed by a shutter. By stopping the action of the modulator, the regular display can be viewed as it is without the shutter.
