    • A double super twisted nematic (DSTN) liquid crystal display (LCD) is provided. The DSTN LCD includes: a liquid crystal display cell having first and second transparent substrates arranged parallel to each other, first and second orientation layers formed on opposing surfaces of the first and second transparent substrates, respectively, a liquid crystal sealed between the first and second transparent substrates, and indium tin oxide (ITO) electrodes formed on the opposing surfaces of the first and second transparent substrates while crossing each other; and a liquid crystal compensation cell having a third transparent substrate attached on the second transparent substrate, a fourth transparent substrate arranged in parallel to the third transparent substrate, third and fourth orientation layers formed on each opposing surface of the third and fourth orientation layers, and a liquid crystal sealed between the third and fourth orientation layers, wherein the pre-tilted angle of the liquid crystal sealed between the first and second orientation layers differs from the pre-tilted angle of the liquid crystal sealed between the third and fourth orientation layers such that the difference between changes in the refractive index anisotropies of the liquid crystals is compensated for.
    • 提供双超扭曲向列(DSTN)液晶显示器(LCD)。 DSTN LCD包括:具有彼此平行布置的第一和第二透明基板的液晶显示单元,分别形成在第一和第二透明基板的相对表面上的第一和第二取向层,密封在第一和第二透明基板之间的液晶 透明基板和形成在第一和第二透明基板的相对表面上的铟锡氧化物(ITO)电极,同时彼此交叉; 以及具有安装在第二透明基板上的第三透明基板的液晶补偿单元,与第三透明基板平行布置的第四透明基板,形成在第三取向层和第四取向层的每个相对面上的第三取向层和第四取向层, 密封在第三和第四取向层之间的液晶,其中密封在第一和第二取向层之间的液晶的预倾角与在第三和第四取向层之间密封的液晶的预倾斜角度不同, 补偿液晶的折射率各向异性变化的差异。
