Title:
LIQUID-CRYSTALLINE COMPOUNDS HAVING BICYCLO[1.1.1]PENTANE STRUCTURE, LIQUID-CRYSTAL COMPOSITION, AND LIQUID-CRYSTAL DISPLAY ELEMENT
Document Type and Number:
WIPO Patent Application WO/1998/035924
Kind Code:
A1
Abstract:
Novel liquid-crystalline compounds which can impart desirable properties to liquid-crystal compositions mainly for use in the TFT, STN, and TN display systems, in particular liquid-crystalline compounds having excellent compatibility at low temperatures, capable of low-voltage operation or high-speed response in various display systems according to substituent selection, capable of giving a highly reliable liquid-crystal composition and having a bicyclo[1.1.1]pentane structure represented by general formula (1), a liquid-crystal composition containing the same; and a liquid-crystal display element prepared from the composition.
