The present invention relates to a liquid crystal composition, and specifically relates to a high-contrast negative liquid crystal composition containing phenylpropylthiophene and an application thereof. The liquid crystal composition comprises at least one compound among compounds represented by general formula I, at least one compound among compounds represented by general formula II, at least one compound among compounds represented by general formula III, and at least one compound among compounds represented by general formula IV. The liquid crystal composition has a high elastic constant and a low rotational viscosity, and when applied to a liquid crystal display, can increase contrast and achieve a quick response time. L'invention concerne une composition de cristaux liquides, et plus particulièrement une composition de cristaux liquides négatifs à contraste élevé, contenant du phénylpropylthiophène, ainsi que son application. La composition de cristaux liquides selon l'invention comprend au moins un co
