Abstract
The present invention provides a liquid crystalline compound having a low viscosity, a high elastic constant ratio, a good stability in humidity, heat and light, a good compatibility with other liquid crystalline compounds, a liquid crystal composition containing the same, and a liquid crystal display element using the liquid crystal composition. Liquid crystalline compounds having the formula (1), in which X represents fluorine atom bromine atom, chlorine atom, or Iodine atom, Ra represents a C2-C15 alkylene group in which any not-adjacent methylene group maybe replaced by line -CH=CH- or -C≡C-, Rb represents C2-C15 alkenyl group, rings A1-A4 independently represents trans -1,4-cyclohexyl or -1,4-phenylene in which one or more hydrogen on a six-member maybe replaced by fluorine atoms (S), Z1-Z3 independently represents a single bond, line -CF2O-, -OCF2-, -CH2O-, -CH2O-, -COO-, -OCO-, ethenylene group, butylene group, ethenylene group, or butenylene group, in which one or more hydrogen atom maybe replaced by fluorine atom (s), and m and n each independently represent 0 or 1, a liquid crystal composition containing the compounds, and liquid crystals display using the composition are provided.
