Zusammenfassung:	The present invention relates to a liquid crystal composition and a liquid crystal display device. The liquid crystal composition has excellent low-temperature stability and a high phase transition temperature, and can exhibit a low rotational viscosity while exhibiting sufficient refractive index anisotropy and dielectric anisotropy. Therefore, by using the liquid crystal composition, a liquid crystal display device having a low threshold voltage, enabling a fast response, and capable of operating in a wide temperature range can be provided. La présente invention concerne une composition de cristaux liquides et un dispositif d'affichage à cristaux liquides. Cette composition de cristaux liquides possède une excellente stabilité à basse température et une température de transition de phase élevée, et peut présenter une viscosité rotationnelle faible tout en présentant une anisotropie d'indice de réfraction et une anisotropie diélectrique, suffisantes. Par conséquent, en utilisant cette composition de cristaux liquides on peut obtenir un dispositif d'affichage à cristaux liquides présentant une faible tension de seuil, permettant une réponse rapide, et capable de fonctionner dans une large plage de températures. 본 발명은 액정 조성물 및 액정 표시 장치에 관한 것이다. 상기 액정 조성물은 우수한 저온 안정성 및 높은 상전이온도를 가지며 충분한 굴절률 이방성 및 유전율 이방성을 나타내면서도 낮은 회전점도를 나타낼 수 있다. 이에 따라, 상기 액정 조성물을 이용하면 낮은 문턱 전압을 가지며 고속 응답이 가능하고 넓은 온도 범위에서 동작할 수 있는 액정 표시 장치를 제공할 수 있다.
