A ferrielectric liquid crystal compound of thengeneral formula (1),n n wherein R is a linear alkyl group having 6 ton12 carbon atoms, either each of X and Y is a hydrogennatom or one of X and Y is a hydrogen atom and the othernis a fluorine atom, m is an integer of 1 to 2, n is 1nand C* is an asymmetric carbon. n The above liquid crystal compound shows anferrielectric phase in a wide temperature range andnexhibits a fast response in spite of its smallnspontaneous polarization, and it is therefore remarkablynuseful for an active-matrix liquid crystal displayndevice. |
