摘要： Provided is a twisted nematic liquid crystal display device which is improved on viewing characteristics of a display contrast, gray-scale characteristics and a display color.
The twisted nematic liquid crystal display device includes a liquid crystal display comprising a liquid crystal cell of a TN type for driving sandwiched by a pair of upper and lower polarizing plates in which, at least one compensating film, which is essentially constituted of a liquid crystalline polymer which optically shows a positive uniaxiality and which is fixed in a nematic hybrid orientational order, is inserted between the liquid crystal cell and the upper polarizing plate, or between the liquid crystal cell and the lower polarizing plate, or at least two compensating films, each of which is essentially constituted of a liquid crystalline polymer which optically shows a positive uniaxiality and which is fixed in a nematic hybrid orientational order, are respectively inserted between the liquid crystal cell and the upper polarizing plate, and between the liquid crystal cell and the lower polarizing plate; and an angle between a tilt direction of a compensating film and a pretilt direction on a liquid crystal cell substrate opposed to a substrate for the liquid crystal cell for driving closest to the compensating film is in the range of 165 to 195 degrees.摘要翻译： 提供了扭曲向列型液晶显示装置，其在显示对比度，灰度特性和显示颜色的观看特性方面得到改进。 该扭曲向列型液晶显示装置包括液晶显示器，该液晶显示器包括用于驱动的TN型液晶盒，该液晶盒被一对上和下偏振片夹在中间，其中至少一个补偿膜基本上由液晶 在液晶单元和上偏振片之间，或者在液晶单元和下偏振片之间或者至少两个补偿膜之间插入光学显示正单轴性并且以向列混合取向顺序固定的聚合物， 其每一个基本上由光学显示正单轴性并且以向列混合取向顺序固定的液晶聚合物构成，分别插入在液晶单元和上偏振板之间以及液晶单元和液晶单元之间 下偏光板; 并且补偿膜的倾斜方向和与驱动用液晶盒的基板相对的液晶单元基板上的预倾方向之间的角度最接近补偿膜的角度在165至195度的范围内。
