Abstract
(EN)
The present invention relates to: a positive liquid crystal composition which has a dielectric anisotropy (∆ε) useful as a liquid crystal display material; and a liquid crystal display element which uses this positive liquid crystal composition. A liquid crystal composition of the present invention has a liquid crystal phase of a wide temperature range, low viscosity, good solubility at low temperatures, high resistivity, high voltage holding ratio, and stability with respect to heat and light. A liquid crystal display element which has excellent display quality and is not susceptible to display defects such as screen burn-in and dropping marks can be achieved by using this liquid crystal composition. This liquid crystal display element which uses a liquid crystal composition of the present invention is useful as a liquid crystal display element for active matrix driving, and is applicable to liquid crystal display elements of TN mode, IPS mode, FFS mode and the like.

La présente invention concerne une composition de cristaux liquides positifs, qui a une anisotropie diélectrique (∆ε), utile en tant que matériau d'affichage à cristaux liquides ; et un élément d'affichage à cristaux liquides utilisant cette composition de cristaux liquides positifs. Une composition de cristaux liquides de la présente invention a une phase cristalline liquide sur une large gamme de températures, une faible viscosité, une bonne solubilité aux basses températures, une résistivité élevée, un taux élevé de maintien de la tension, et une stabilité vis-à-vis de la chaleur et de la lumière. Un élément d'affichage à cristaux liquides qui a une excellente qualité d'affichage et n'est pas susceptible d'afficher des défauts tels qu'une image gravée et des marques blanches, peut être réalisé par utilisation de cette composition de cristaux liquides. Cet élément d'affichage à cristaux liquides, qui utilise une composition de cristaux liquides de la présente invention, est utile en tant qu'élément d'affichage à cristaux liquides pour la commande d'une matrice active, et s'applique aux éléments d'affichage à cristaux liquides en mode TN, en mode IPS, en mode FFS et analogues.
