Abstract:
(EN) The present invention addresses the problem of: providing an n-type liquid crystal composition which has improved viewing angle characteristics while satisfying various properties required of so-called n-type liquid crystal compositions having negative dielectric anisotropy (Δε); and providing a liquid crystal display device using the n-type liquid crystal composition. Provided are: a liquid crystal composition having negative dielectric anisotropy, wherein the total content of a compound represented by general formula (i) is at least 3% with respect to the total amount of the composition, the total content of a compound represented by general formula (ii) is at least 3% with respect to the total amount of the composition, and the total content of the compound represented by general formula (i) is at least 20% with respect to the total amount of the compound represented by general formula (i), the compound represented by general formula (ii), and a compound represented by general formula (L); and a liquid crystal display device using the liquid crystal composition.
(FR) L’invention a pour objet de fournir une composition de cristaux liquides de type n qui tout en satisfaisant une anisotropie diélectrique (Δε) négative, dite caractéristique requise pour les compositions de cristaux liquides de type n, présente des caractéristiques d’angle de vision améliorées, et a pour objet, en outre, de fournir un élément d’affichage à cristaux liquides. Ainsi, l’invention fournit une composition de cristaux liquides d’anisotropie diélectrique négative, et un élément d’affichage à cristaux liquides mettant en œuvre cette composition. Ladite composition de cristaux liquides présente une teneur totale en composé représenté par la formule générale (i) supérieure ou égale à 3% pour la masse totale de composition, une teneur totale en composé représenté par la formule générale (ii) supérieure ou égale à 3% pour la masse totale de composition, et une teneur totale en composé représenté par la formule générale (i) supérieure ou égale à 20% pour la masse totale de composé représenté par la formule générale (i), de composé représenté par la formule générale (ii) et de composé représenté par la formule générale (L).
(JA) 本発明が解決しようとする課題は、誘電率異方性(Δε)が負のいわゆるn型液晶組成物に求められる諸特性を満たしつつ、視野角特性が改善したn型液晶組成物を提供し、あわせてこれを用いた液晶表示素子を提供することである。 組成物全量に対する一般式(i)で表される化合物の合計の含有量が3%以上であり、組成物全量に対する一般式(ii)で表される化合物の合計の含有量が3%以上であり、一般式(i)で表される化合物、一般式(ii)で表される化合物及び一般式(L)で表される化合物全量に対する一般式(i)で表される化合物の合計の含有量が20%以上である誘電率異方性が負の液晶組成物を提供し、あわせてこれらを使用した液晶表示素子を提供する。
