摘要：
A liquid crystal compound of the formula (1) ##STR1## wherein R is a linear alkyl group having 6 to 12 carbon atoms, both X and Y are hydrogen atoms or one of X and Y is a fluorine atom and the other is a hydrogen atom, A is --CF.sub.3 or --C.sub.2 F.sub.5, m is an integer of 2 to 4, n is an integer of 2 to 4, and C* is an asymmetric carbon, having a ferrielectric phase in its phase sequence, or a ferrielectric liquid crystal composition containing the liquid crystal compound of the formula (1) having a ferrielectric phase, may be injected between substrates provided with nonlinear active elements, such as thin film transistors or diodes formed on each pixel, to form an active matrix liquid crystal display device.
