Title (EN) LIQUID CRYSTAL COMPOSITION AND LIQUID CRYSTAL ELEMENT
(FR) CRISTAUX LIQUIDES ET ELEMENT A CRISTAUX LIQUIDES
Abstract: front page image
(EN)A liquid crystal composition comprising a liquid crystal compound and at least one cyclic ether compound such as crown ether, azacrown, silacrown, cryptand, etc., and a liquid crystal element comprising said composition sandwiched in between two base plates at least one of which is provided with a transparent electrode. The invention is directed to providing a liquid crystal element undergoing less electrostatic hazards and a stable liquid crystal composition having a low resistivity for substantiating such an element.
(FR)Composition à base de cristaux liquides comprenant un composé de cristaux liquides et au moins un composé d'éther cyclique tel que de l'éther crown, azacrown, silacrown, cryptand, etc., et élément à cristaux liquides comprenant ladite composition en sandwich entre deux plaques de base, dont l'une au moins est pourvue d'une électrode transparente. L'objet de l'invention est la production d'un élément à cristaux liquides moins sensible aux perturbations électrostatiques, ainsi que d'une composition à base de cristaux liquides stable et présentant une faible résistivité, permettant de réaliser ledit élément.
