Title (EN) COMPOUND HAVING TETRAHYDRONAPHTHALENE SKELETON AND LIQUID CRYSTAL COMPOSITION CONTAINING THE SAME
(FR) COMPOSE PRESENTANT UN SQUELETTE TETRAHYDRONAPHTALENE ET COMPOSITION DE CRISTAUX LIQUIDES CONTENANT CE COMPOSE
Abstract: front page image
(EN)A tetrahydronaphthalene derivative represented by general formula (I) and a liquid crystal composition containing the same. The compound having general formula (I) has not only excellent properties as a liquid crystal, but also excellent compatibility with a liquid crystal compound or composition being currently used, and further the addition thereof to such a compound or composition allows the marked reduction of a threshold value for voltage with little detriment to response characteristics. The above compound can be commercially produced with ease, and is colorless and chemically stable. Accordingly, a liquid crystal composition containing the compound is a practical liquid crystal which is extremely useful for a liquid crystal display which requires a wide working temperature range, an operation at a low voltage and a fast response.
(FR)L'invention concerne un dérivé de tétrahydronaphtalène représenté par la formule générale (I), ainsi qu'une composition de cristaux liquides contenant ce dérivé. Le composé de formule générale (I) possède non seulement d'excellentes propriétés en tant que cristal liquide, mais également une excellente compatibilité avec un composé ou une composition de cristaux liquides. L'ajout du composé de l'invention au composé ou composition de cristaux liquides permet la réduction sensible d'une valeur de seuil de tension, sans nuire sensiblement aux caractéristiques de transfert. Le composé de l'invention, qui est incolore et chimiquement stable, peut être produit commercialement avec facilité. L'invention concerne également une composition de cristaux liquides contenant ledit composé qui constitue un cristal liquide extrêmement utile pour un affichage à cristaux liquides nécessitant un large gamme de températures d'emploi, un fonctionnement avec une faible tension et une réaction rapide.
