To provide liquid-crystalline compounds.SOLUTION: The invention provides compounds of the formula I, a process for preparation thereof, liquid-crystalline media comprising at least one compound of the formula I, and electro-optical displays containing a liquid-crystalline medium of this type. The compounds of the formula I include, as a structural element, a combination of a 1,4-substituted cyclohexene ring besides a dioxane or tetrahydropyran ring and a substituted biphenyl group. (In the formula, Y1 denotes -O- or -CH2-, and the groups R1, L1 to L6 and X1 have the meanings indicated in claim 1.)SELECTED DRAWING: None 【課題】液晶化合物を提供する。【解決手段】式Ｉの化合物。その調製方法、少なくとも１種類の式Ｉの化合物を含む液晶媒体、およびこのタイプの液晶媒体を含む電気光学的ディスプレイ。式Ｉの化合物は構造要素として、ジオキサンまたはテトラヒドロピラン環および置換ビフェニル基の他に１，４−置換シクロヘキセン環の組合せを含む。（式中、Ｙ１は−Ｏ−または−ＣＨ２−を表し、基Ｒ１、Ｌ１〜Ｌ６およびＸ１は請求項１で示される意味を有する。）【選択図】なし
