摘要： An IPS-mode transflective LCD device includes an array of pixels each including a reflective region and a transmissive region juxtaposed. The reflective region operates in a normally-white mode, and the transmissive region operates in a normally-black mode. A common data signal is supplied to the reflective region and transmissive region, whereas the common electrode signal in the transmissive region is an inverted signal of the common electrode signal in the reflective region, to thereby obtain similar gray-scale levels.

摘要： 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.
