The present invention relates to a compound represented by chemical formula I, wherein, in the chemical formula I, Y^1 represents -O- or -CH_2-, and each of R^1, L^1-L^6 and X^1 is the same as defined in claim 1. The present invention also relates to a method for preparing a compound represented by the chemical formula I, a liquid crystal medium including at least one compound represented by chemical formula I, and an electro-optical display including the liquid crystal medium. The compound represented by the chemical formula I includes, as a structural element, a combination of a 1,4-substituted cyclohexene ring with a substituted biphenyl group, in addition to a dioxane or tetrahydropyran ring. 하기 화학식 I의 화합물이 본원에 개시된다:상기 식에서, Y은 -O- 또는 -CH-이고, 기 R, L내지 L및 X은 제1항에 정의된 바와 같다. 화학식 I의 화합물의 제조 방법, 하나 이상의 화학식 I의 화합물을 포함하는 액정 매질, 및 이러한 유형의 액정 매질을 포함하는 전기-광학 디스플레이가 본원에 개시된다. 화학식 I의 화합물은 구조적 요소로서 다이옥산 또는 테트라하이드로피란 고리 외에 1,4-치환된 사이클로헥센 고리와 치환된 바이페닐 기의 조합을 포함한다.
