    • PURPOSE: A liquid crystal medium which is low in viscosity and has a shorter reaction time is provided, which is used in a liquid crystal display of an active matrix addressed system, in particular a liquid crystal display using an active matrix containing a thin film transistor or varistor. CONSTITUTION: The liquid crystal medium is a nematic liquid crystal medium and comprises (a) a dielectrically negative liquid crystal component which is one or more compounds of formula 1, (b) a dielectrically negative liquid crystal component of formula 2 and 3, and optionally (c) a dielectrically neutral liquid crystal component of formula 4, and optionally (d) a dielectrically positive liquid crystal component of formula 5. In formula, R11 is a 1-7C alkyl, 1-7C alkoxy or 2-7C alkenyloxy group; R12 is a 1-7C alkyl or alkoxy group or a 2-7C alkenyl, alkenyloxy or alkoxyalkyl group; one of Z11 and Z12 is OCF2 or CF2O and the other is a single bond; and n is 0 or 1.
    • 目的:提供一种粘度低,反应时间短的液晶介质,其用于有源矩阵寻址系统的液晶显示器,特别是使用含有薄膜晶体管的有源矩阵的液晶显示器 或压敏电阻。 构成:液晶介质是向列型液晶介质,并且包括(a)作为一种或多种式1化合物的介电负极性液晶组分,(b)式2和3的介电性负极性液晶组分,和任选地 (c)式4的介电中性液晶组分,和任选地(d)式5的介电阳性液晶组分。在式中,R11是1-7C烷基,1-7C烷氧基或2-7C烯氧基; R12是1-7C烷基或烷氧基或2-7C烯基,烯氧基或烷氧基烷基; Z11和Z12之一为OCF2或CF2O,另一个为单键; n为0或1。
