    • A pair of transparent substrates are arranged to oppose each other and bonded to each other through a seal member. A polymer dispersed liquid crystal layer and spacers are provided between the pair of transparent substrates. A plurality of pixel electrodes respectively provided with TFTs are disposed in a matrix form on the counter surface of one substrate opposing the other substrate, and the spacers for regulating the gap between the substrates are fixed, through resin films, to remaining regions of the counter surface of one substrate obtained by excluding pixel regions corresponding to the pixel electrodes from the region inside the seal member. A black mask is formed on the remaining regions of the counter surface of the other transparent substrate, and a flat counter electrode opposing the plurality of pixel electrodes is formed on the black mask. The polymer dispersed liquid crystal display device is obtained by injecting, into a cell in a vacuum state, a solution mixture of a photo-setting polymeric material and a liquid crystal material that are mixed in a formulating proportion not less than a solubility at a normal temperature and a normal pressure, increasing the temperature of the solution mixture to a temperature not less than the soluble limit temperature of the liquid crystal, and thereafter photo-setting the photo-setting polymeric material.

    • In a liquid crystal display device using color filters, the area of each of color filters arranged on the inner surface of one of substrates in correspondence with the pixel areas is set to be smaller than that of each pixel area to form non-colored light exit areas, and color pixels are displayed with non-colored light which is not transmitted through the color filters and colored light which is transmitted through the color filters. Since high-luminance color pixels are displayed with these colored light and non-colored light, the screen can be made brighter. The liquid crystal display device further includes a reflecting member for reflecting external light incident from the front side of the device and transmitted through the liquid crystal layer toward the front side. In addition, in the liquid crystal display device, reflecting films for reflecting light incident from the front side of the device toward the front side are arranged on the inner surface of the front-side substrate in correspondence with the areas between the respective pixel areas, thereby making the portions between the respective pixel areas bright and further increasing the overall brightness of the screen.
    • 在使用滤色器的液晶显示装置中,将与像素区域对应地配置在一个基板的内表面上的各滤色器的面积设定为小于各像素区域的面积,形成无色光出射 区域和彩色像素以不透过滤色器的非彩色光和通过滤色器透射的彩色光显示。 由于利用这些彩色光和非彩色光显示高亮度彩色像素,因此可以使屏幕变亮。 液晶显示装置还包括反射构件,用于反射从装置的前侧入射的外部光并透过液晶层朝向前侧。 此外,在液晶显示装置中,对应于各像素区域之间的区域,在前侧基板的内表面上配置用于将从装置的前侧入射的光反射到前侧的反射膜, 从而使各个像素区域之间的部分变亮,并进一步增加屏幕的整体亮度。

    • One frame of a video signal is separated to a plurality of display frames. To display a color specified by the video signal by mixing display colors of a plurality of display frames, the video signal is converted to data indicative of a voltage to be applied to each pixel over the display frames by using a conversion table. A voltage corresponding to the converted data is applied to a birifringence control type liquid crystal display device to drive the liquid crystal display device multiple times in one frame period of the video signal. When the response speed of the liquid crystal is fast, a color obtained by mixing the display colors of a plurality of display frames is recognized by an observer. When the response speed of the liquid crystal is slow, a color corresponding to an average value of the voltages applied to a plurality of display frames is recognized by the observer. When the liquid crystal has an intermediate response speed, a color obtained by visually mixing a series of display colors displayed during the transition of the alignment state of the liquid crystal is recognized by the observer.
    • 一帧视频信号被分离成多个显示帧。 为了通过混合多个显示帧的显示颜色来显示由视频信号指定的颜色,通过使用转换表将视频信号转换为指示要施加到显示帧上的每个像素的电压的数据。 将对应于转换数据的电压施加到双向控制型液晶显示装置,以在视频信号的一个帧周期内多次驱动液晶显示装置。 当液晶的响应速度快时,由观察者识别通过混合多个显示框的显示颜色而获得的颜色。 当液晶的响应速度慢时,与观察者识别对应于多个显示框的电压的平均值相对应的颜色。 当液晶具有中间响应速度时,通过视觉上混合在液晶的取向状态的转变期间显示的一系列显示颜色而获得的颜色被观察者识别。

    • This invention relates to an optical card having a preformat portion comprising a low reflectance area having an excellent contrast to high reflectance area. An optical card original plate whose portions corresponding to preformat portions 4, 5 of an optical card 1 each have a stereostructure of an inverted pyramidal shape is prepared. An optical card is duplicated from this optical card original plate. The stereostructure in an inverted pyramidal shape can be formed by the anisotropic etching of a single crystal substrate. An original plate free from defects and surface roughnesses and ensuring a sufficiently low reflectance is obtained. An optical card produced from this original plate has a preformat portion comprising a low reflectance area with a satisfactory contrast to a high reflectance area. A replica duplicated using a molding resin from the original plate can be used as a resin original plate. Furthermore, a replica duplicated from this resin original plate by use of a molding resin can be used as a stamper for production of an optical card.
