摘要： The present invention provides a monostable ferroelectric liquid crystal display apparatus includes a pair of substrates, each subjected to uniaxial orientation processing and arranged so that their orientation processing directions are approximately parallel to each other; and a ferroelectric liquid crystal material having the chiral smectic C phase filled between the substrates, the liquid crystal material being such that the projection component of the cone drawn by a liquid crystal molecule of the ferroelectric liquid crystal material projected onto the substrate and the projection component of the liquid crystal molecule itself projected onto the substrate in the molecule axis direction are respectively identical to the orientation processing direction of the substrates, which state is the initial state of the monostable configuration, wherein the ferroelectric liquid crystal contains a compound having a phenyl pyrimidine skeleton having one end connected to an alkoxyl chain and the other end connected to an alkyl chain, wherein sum of carbons in the alkoxyl chain and the alkyl chain is 15. This enables to realize a monostable mode with a sufficient stability even at low temperature and a sufficient analog tone and contrast ratio.
摘要翻译：本发明提供一种单稳态铁电液晶显示装置，包括：一对基板，各自进行单轴取向处理，并使其取向处理方向大致平行; 以及在基板之间填充有手性近晶C相的铁电液晶材料，液晶材料使得由突出于基板上的强电介质液晶材料的液晶分子拉出的锥体的投影分量和投影部件在分子轴方向上投射到基板上的液晶分子本身分别与基板的取向处理方向相同，该状态是单稳态结构的初始状态，其中铁电液晶含有具有苯基嘧啶的化合物骨架的一端连接到烷氧基链，另一端连接到烷基链，其中烷氧基链和烷基链中的碳的和为15.这使得即使在低温下也能实现具有足够稳定性的单稳态模式，足够的模拟音调和对比度。

摘要： A liquid crystal display device of a multi-domain vertical-alignment mode includes a driving substrate having a pixel electrode, a counter substrate opposing the driving substrate and having a counter electrode, and a liquid crystal sandwiched between the substrates. In the liquid crystal display device, molecules of the liquid crystal are aligned nearly perpendicularly to the substrates when no electric field is produced, and are aligned nearly horizontally by the application of a predetermined voltage. The counter substrate has an alignment center portion for orienting the molecules of the liquid crystal in all directions centered on a certain point when the voltage is applied. The area of the alignment center portion of the counter substrate is set to be less than or equal to 5% of the area of one pixel.

摘要： A liquid crystal display device where a liquid crystal section is vertically oriented with respect to both a first substrate capable of transmitting light and a second substrate which includes a reflecting region and a transmitting region. A pair of retardation films are disposed on both sides of the vertically oriented liquid crystal section, and have symmetrical phase characteristics over a visible wavelength region. Lagging phase axes of the pair of retardation films intersect each other, with an intersecting angle thereof being set in a range of from 90°±10°. Relative shifts in phase differences of the pair of retardation films are controlled within a range of ±30 nm. The reflective-and-transmissive liquid crystal display device makes it possible to provide, a high contrast and a high transmittance ratio in a transmission display mode and, a high contrast and a high reflection ratio in a reflection display mode.
