摘要： A ferroelectric liquid crystal display device of the present invention includes: a pair of substrates; a ferroelectric liquid crystal layer provided between the pair of substrates; and an electrode for applying a voltage to the ferroelectric liquid crystal layer, wherein the ferroelectric liquid crystal layer has bent smectic layers, and an effective bend angle .theta.L of the bent smectic layers satisfies the relationship: .theta.Leff>.theta.L>0.degree. in a temperature range in which the ferroelectric liquid crystal display device is stored, where an effective bend angle of the smectic layers in a first state is .theta.Leff, the first state being obtained by cooling the ferroelectric liquid crystal layer from a temperature higher than a phase transition temperature of a chiral smectic C phase--a smectic A phase to a temperature not higher than a phase transition temperature of the chiral smectic C phase--the smectic A phase.

摘要： A liquid crystal display unit including a plurality of subpixels in each pixel provides superior gradation over a wide viewing angle, and is produced with no increase in manufacturing cost and no deterioration of desired properties (such as reduction in brightness, contrast and response). No additional manufacturing step is required since a control capacitor electrode is formed at the same time as source and drain electrodes constituting a thin-film transistor. By controlling the ratio of display area and the difference in applied voltage of the subpixels, preferable viewing angle properties are obtained. The display properties at the boundary of subpixels are improved by controlling the gap width and the direction of boundary of the subpixels, thus providing a bright display.
摘要翻译：在每个像素中包括多个子像素的液晶显示单元在宽视角上提供优异的等级，并且不会增加制造成本并且不会降低期望的性能（诸如亮度，对比度和响应的降低）。不需要额外的制造步骤，因为控制电容器电极与构成薄膜晶体管的源极和漏极同时形成。通过控制显示区域的比例和子像素的施加电压的差异，可以获得优选的视角特性。通过控制子像素的间隙宽度和边界方向来改善子像素边界处的显示特性，从而提供明亮的显示。
