Abstract:
A process for producing a liquid crystal composition comprising steps of:(a) selecting liquid crystalline compounds and their content by using, as a parameter, the number of carbon atoms in the portions of acyclic hydrocarbon in liquid crystalline compounds from which said liquid crystal composition is composed, in the range wherein the total number of carbon atoms in the portions of acyclic hydrocarbon in the liquid crystalline compounds is 4 to 24, and the average value of the total number of carbon atoms in the portions of acyclic hydrocarbon in the liquid crystalline compounds in the liquid crystal composition is 5 or more, so that the voltage holding ratio of a cell of said liquid crystal is a prescribed value or higher when the cell of said liquid crystal was prepared by filling said liquid crystal composition, and(b) combining said liquid crystalline compounds.
