摘要： As a liquid crystal compound, a dicyclohexylethylene derivative, which has a wide liquid crystal phase temperature range, a low viscosity, a large .DELTA..epsilon. value, a high stability, and an excellent compatibility with other liquid crystal compounds. The dicyclohexylethylene derivative is represented by general formula (I), ##STR1## wherein R represents C.sub.1 -C.sub.10 linear alkyl; and X represents fluorine or trifluoromethyl. This compound can widen the working range of a liquid crystal display element because of its high NI point, can improve the response speed of the display element because of its low viscosity, and can lower the voltage for driving the display element because of its high positive .DELTA..epsilon. value. Furthermore, it is so stable against changes in environmental factors that it can be used in various liquid crystal display elements of, for example, active matrix drive type using TFT.
