摘要： A polycyclic compound of general formula (I): R - X - [A - X ] - [A - X ] - R (=wherein R is C6-C16 (halo)alkyl; X is -O- or a single bond; A is biphenylene, phenylene or the like; A is 1-fluoro-3,4-dihydronaphthalene or the like; X and X are each -COO-, a single bond or the like; and R is an optically active group having at least one asymmetric carbon atom and 4 to 20 carbon atoms); a liquid-crystal material composed of the above polycyclic compound; and a liquid-crystal composition and a liquid-crystal device containing the material. This novel polycyclic compound is optically active, exhibits a smectic phase over a wide temperature range including room temperatures, and can be used as a ferroelectric or antiferroelectric liquid-crystal material. The use of the liquid-crystal material makes it possible to produce a liquid-crystal device exhibiting a rapid response over a wide temperature range.

摘要： A smectic liquid-crystal composition according to the first embodiment is characterized in that a voltage gradation parameter L(=SH/SO) is less than 0.6, when a voltage is impressed upon a liquid-crystal cell that is filled with this composition and is put between a pair of polarizing plates placed at the position of crossed nicols to prepare a hysteresis curve relating to the voltage and light transmittance, and the tangent IR of the curve where the transmittance steeply increases as the voltage is impressed intersects at the point P with the tangent IF of the curve adjacent to the above curve on the high-voltage side. A liquid-crystal composition according to the second embodiment is characterized in that a parameter G as defined by the equation (B) is 0 to 0.3 (wherein S represents the area of the region surrounded by the hysteresis curve, Tmin represents the minimum value of the transmittance, and To represents the transmittance when no voltage is impressed), when the transmittance reaches the maximum value Tmax as the absolute value |V| of the impressed voltage is increased to exceed a given value |V|min.
摘要翻译：根据第一实施方案的近晶型液晶组合物的特征在于，当将电压施加到填充有该组合物的液晶单元时，电压灰度参数L（= SH / SO）小于0.6，并且是放置在位于正交尼科尔位置的一对偏振板之间，以制备与电压和透光率有关的滞后曲线，并且随着电压的增加，透射率急剧增加的曲线的切线IR在点P处相交，在高压侧与上述曲线相邻的曲线的切线IF。根据第二实施方案的液晶组合物的特征在于，由式（B）定义的参数G为0至0.3（其中S表示由滞后曲线包围的区域的面积，Tmin表示透射率，To表示没有施加电压时的透射率），当透射率达到最大值Tmax时，绝对值| V | 外加电压增加到超过给定值| V | min。
