Abstract[English]
The present invention relates to the technical field of liquid crystal display, and provides a liquid crystal compound, a preparation method therefor and a use thereof. The liquid crystal compound has a structure as shown in general formula I. The liquid crystal compound provided by the present invention has a large negative dielectric anisotropy and a moderate rotational viscosity, and can effectively reduce the driving voltage of a liquid crystal display device to which the liquid crystal compound is applied, improve the response speed of the liquid crystal display device, and enable the liquid crystal display device to have a moderate optical anisotropy and a high charge retention rate.[French]
La présente invention se rapporte au domaine technique des écrans à cristaux liquides, et concerne en particulier un composé de cristaux liquides, son procédé de préparation et son utilisation. Le composé de cristaux liquides a une structure telle que représentée dans la formule générale I. Le composé de cristaux liquides selon la présente invention possède une grande anisotropie diélectrique négative et une viscosité rotationnelle modérée, et peut réduire efficacement la tension de commande d'un écran à cristaux liquides auquel le composé de cristaux liquides est appliqué, améliorer la vitesse de réponse de l'écran à cristaux liquides, et permettre à l'écran à cristaux liquides d'avoir une anisotropie optique modérée et un taux de rétention de charge élevé.[Chinese]
