摘要： A front-illuminating device of the present invention, which is placed over the entire surface of an object to be illuminated such as a reflection-type liquid crystal display device when it is used, is provided with a light source and a light-directing body. The light-directing body has an incident surface on which light from the light source (light-source light) is made incident, a first light-releasing surface for releasing the light toward the object to be illuminated, and a second light-releasing surface which faces the first light-releasing surface and releases reflected light from the object to be illuminated. The second light-releasing surface is formed into a step shape in which slanting portions and flat portions are alternately placed. The light source light, released from the first light-releasing surface to the object to be illuminated, is reflected by the object to be illuminated and the reflected light is allowed to reach the observer from the first light-releasing surface through the flat portions. In this case, among the light-source light rays, the light components progressing in parallel with the flat portions are reflected by the slanting portions and directed to the object to be illuminated. Consequently, the present invention makes it possible to provide a brighter front-illuminating device in which the efficiency of use of the light-source light is improved.

摘要： A liquid crystal device includes a pair of substrates, a liquid crystal layer interposed between the pair of substrates, at least one polarizing element, and a plurality of pixels. A retardation (d.times..DELTA.n) of the liquid crystal layer satisfies the relation:d.times..DELTA.n>.lambda./2when incident light is output after passing through the liquid crystal layer once. The retardation satisfies the relation:2d.times..DELTA.n>.lambda./2when the incident light is output after passing through the liquid crystal layer twice. In these relations, d a thickness of the liquid crystal layer, .DELTA.n is a birefringence, and .lambda. is a wavelength of the light incident on the liquid crystal layer. A driving voltage supplier applies a driving voltage including a voltage higher than a maximum voltage providing an extremum of the output light intensity in a voltage-output light intensity characteristic of the pixels to the plurality of pixels. Such application of the driving voltage allows utilization of a relaxation process of liquid crystal molecules in the liquid crystal layer to obtain a predetermined light output density.
摘要翻译：液晶装置包括一对基板，插入在该对基板之间的液晶层，至少一个偏振元件和多个像素。当通过液晶层一次后输出入射光时，液晶层的延迟（dx DELTA n）满足关系：dxDDTA>λ/ 2。当通过液晶层两次后输出入射光时，该延迟满足关系：2dxΔDTA>λ/ 2。在这些关系中，d是液晶层的厚度，ΔTAn是双折射，λ是入射到液晶层上的光的波长。驱动电压供给器将包括高于提供输出光强度的极值的最大电压的电压施加到多个像素的电压输出光强度特性中的驱动电压。驱动电压的这种施加允许利用液晶层中的液晶分子的松弛过程以获得预定的光输出密度。
