A new liquid crystal compound comprises two condensed and substituted rings. The ring preferably is a five-membered heterocyclic ring. The heterocyclic ring is preferably condensed with benzene ring or an aromatic six-membered heterocyclic ring. The benzene ring or the aromatic six-membered heterocyclic ring is preferably substituted with a group comprising a cyclic structure and a chain structure. The liquid crystal compound is advantageously used in preparation of a thin phase retarder, such as a wide-ranged l/4 plate, which gives inverse wavelength distribution. The phase retarder can be easily produced according to a simple process by using the new liquid crystal compound.
一种新的液晶化合物包括两个凝缩和取代的环。该环最好是一个五元杂环。该杂环最好与苯环或芳香六元杂环凝缩。苯环或芳香六元杂环最好取代为一个包含环结构和链结构的基团。该液晶化合物有利地用于制备薄相位延迟器,如宽范围的1/4波片,其提供反向波长分布。根据使用新的液晶化合物可以通过简单的工艺容易地生产相位延迟器。
