A liquid crystal display device comprises a pair of substrates (101, 101') whose spacing is determined by spacers (1412, 1711) placed in a non-displaying region, a liquid crystal layer (106) filled in the space between said pair of substrates, a set of electrodes (102, 103) formed on the surface of one of the substrates of said pair of substrates for applying an electric field to said liquid crystal layer, and a pair of optical polarizers (109, 109') placed so that they enclose said liquid crystal layer and with their axes of polarization almost at right angles to each other. The liquid crystal layer contains 40% or more weight percentage or 100% or less weight percentage of a constituent component with a dielectric anisotropy of Δε ≤ 1, and the directions of controlled orientation of liquid crystal molecules at the two surfaces between said liquid crystal layer and said pair of substrates is almost parallel. The axis of polarization of one of the polarizers is almost aligned with the direction of controlled orientation of liquid crystal molecules at said surfaces.
一种液晶显示设备包括一对基板(101,101'),其间距由放置在非显示区域的隔板(1412,1711)决定;一个液晶层(106),填充在所述一对基板之间的空间;一组电极(102.103.103),形成于所述一对基板中的一个基板表面,用于向所述液晶层施加电场;以及一对光学偏振器(109,109'),放置于所述一对基板中的一个基板表面,以便将它们包围起来、103),以及一对光学偏振器(109,109'),放置的位置使它们包围所述液晶层,并且它们的偏振轴几乎互成直角。液晶层含有 40% 或更高重量百分比或 100% 或更低重量百分比的介电各向异性为 Δε ≤ 1 的成分,液晶分子在所述液晶层和所述一对基板之间的两个表面上的受控取向方向几乎平行。其中一个偏振器的偏振轴几乎与所述表面上液晶分子的受控取向方向一致。
