Abstract: Provided is a display device having a viewing angle changing function, which is capable of preventing leakage of information displayed on a display screen even when there is a fault generated in changing the viewing angle. The image display device including a viewing angle changing element capable of changing a wide vision display and a narrow vision display and including a display element is provided with a detection element which detects a fault generated in the viewing angle changing element and a module for changing to a narrow vision display when there is a fault based on a detection value of the detection element. For example, when there is a fault, a transparent heater is operated to heat a liquid crystal layer to set a transparent-scattering changing element to a transparent state and forcibly set the display device to a narrow vision display.

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 small light source unit of simple structure that emits light forward with high efficiency is well-suited as a backlight in a liquid crystal display device. The light director in this unit has reflective internal faces adjacent opposite peripheral regions of the entrance face and two refractive index interfaces in it. The reflective internal faces and the refractive index interfaces are oriented on inclined planes. The refractive index of a middle region between the two interfaces is the smallest among those of the three regions making up the light director.

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: A display device, capable of changing view angle range and suitable for reducing thickness and weight, is provided. One compensating panel has such a structure that two polymer films, having birefringence, adhere to each other. The birefringence directions of the polymer films are parallel or orthogonal to the liquid crystal orientation direction. Similarly, another compensating panel has such a structure that two polymer films, having birefringence, adhere to each other. The birefringence directions of the polymer films are parallel or orthogonal to the liquid crystal orientation direction. Since the compensating panel does not include glass substrates but includes polymer films, the display device can be thin and light.
