PROBLEM TO BE SOLVED: To find a stable novel liquid crystal compound or mesogen compound having a negative or slightly positive dielectric anisotropy, which is suitable for a liquid crystal medium component, in particular, a TFT and an STN display. Especially suitable as a component of the liquid crystal medium of the display based on the effect of twisted cell law, guest-host effect, effect of ordered phase deformation (DAP), electrically controlled birefringence (ECB), dynamic scattering effect Provided are a liquid crystal compound, a liquid crystal medium including the same, and a liquid crystal display device. A cyclohexane derivative of the general formula I: A specific example of a compound of general formula I is 4'-pentyl-4-propylbicyclohexyl-4-ol. |
