Abstract
(EN)
A liquid crystal composition and a liquid crystal display containing same. The liquid crystal composition comprises: a compound of general formula (I) which occupies 1%-50% of the total weight of the liquid crystal composition; a compound of general formula (II) which occupies 1%-60% of the total weight of the liquid crystal composition; a compound of general formula (III) which occupies 1%-60% of the total weight of the liquid crystal composition; and a compound of general formula (IV) which occupies 0-50% of the total weight of the liquid crystal composition. The liquid crystal composition has a suitably wider nematic phase scope, a suitable optical anisotropy, a favourable low-temperature storage stability and a faster response speed, and can be used for outdoor work, the image display effect is good, and there is no streaking phenomenon.

L'invention concerne une composition de cristaux liquides et un écran à cristaux liquides la contenant. La composition de cristaux liquides comprend : un composé de formule générale (I) qui représente 1 à 50 % du poids total de la composition de cristaux liquides; un composé de formule générale (II) qui représente 1 à 60 % du poids total de la composition de cristaux liquides; un composé de formule générale (III) qui représente 1 à 60 % du poids total de la composition de cristaux liquides; et un composé de formule générale (IV) qui représente 0 à 50 % du poids total de la composition de cristaux liquides. La composition de cristaux liquides présente une étendue de la phase nématique plus large appropriée, une anisotropie optique appropriée, une stabilité au stockage à température basse favorable et une vitesse de réponse plus rapide, et peut être utilisée pour le travail en extérieur, l'effet d'affichage d'images est bon, et il n'y a pas de phénomène de stries.
