Zusammenfassung:	The present invention relates to a liquid crystal composition with a large elastic constant of a negative liquid crystal compound having a methoxy bridge bond and the use thereof. The liquid crystal composition comprises at least one or more compounds represented by general formula I, one or more compounds represented by general formula II and one or more compounds represented by general formula III. The liquid crystal composition of the present invention has a large elastic constant and a fast response time, and can improve the contrast of a liquid crystal display when used in the liquid crystal display. (I), (II), (III) La présente invention concerne une composition de cristaux liquides ayant une grande constante élastique d'un composé cristallin liquide négatif ayant une liaison en pont méthoxy et une utilisation associée. La composition de cristaux liquides comprend un ou plusieurs composés représentés par la formule générale I, un ou plusieurs composés représentés par la formule générale II et un ou plus
