Zusammenfassung:The present invention relates to a liquid crystal compound represented by chemical formula 1 below. More specifically, according to the present invention, the liquid crystal compound has high refractive anisotropy, and thus can provide a liquid crystal composition optimized for various liquid crystal display devices, particularly, VA, MVA, PVA, PS-VA, PALC, FFS, PS-FFS, IPS or PS-IPS mode liquid crystal display devices requiring quick response time. (1) In the formula, R1 to R3, A, L1, L2, X1 to X3 and n are the same as those defined in the description. La présente invention concerne un composé à cristaux liquides représenté par la formule chimique 1 ci-dessous. Plus particulièrement, selon la présente invention, le composé à cristaux liquides présente une anisotropie de réfraction élevée et permet ainsi d'obtenir une composition de cristaux liquides optimisée pour divers dispositifs d'affichage à cristaux liquides, en particulier des dispositifs d'affichage à cristaux liquides en mode VA, MVA, PVA, PS-VA, PALC, FFS, PS-FFS, IPS ou PS-IPS nécessitant un temps de réponse rapide. (1) Dans la formule, R1 à R3, A, L1, L2, X1 à X3 et n sont les mêmes que ceux définis dans la description. 하기 화학식 1로 표시되는 액정 화합물에 관한 것이다. 보다 상세하게는, 본 발명에 따른 액정 화합물은 고굴절률 이방성을 가지며, 따라서 다양한 액정 표시 소자, 특히 신속한 응답 시간을 요구하는 VA, MVA, PVA, PS-VA, PALC, FFS, PS-FFS, IPS 또는 PS-IPS 모드의 액정 표시 소자에 최적화된 액정 조성물을 제공할 수 있다. (1) 상기 식에서, R1 내지 R3, A, L1, L2, X1 내지 X3 및 n은 명세서 내에 정의한 바와 같다.
