A liquid crystal display element includes a cholesteric phase liquid crystal component and a space holding member held within a pair of substrates, wherein at least one of which is transparent. The liquid crystal component is a chiral-nematic liquid crystal material containing a liquid crystal pyrimidine compound having fluorine in the molecule, liquid crystal diphenylacetylene having fluorine in the molecule, and a chiral component. The liquid crystal component may also contain a liquid crystal phenylcyclohexane compound, a liquid crystal cyanobiphenyl compound, and a liquid crystal alkenyl compound. In the present invention, characteristics such as color purity and reflectivity are improved, contrast is increased, and the drive voltage can be reduced by including in the nematic liquid crystal component a liquid crystal pyrimidine compound having fluorine within the molecule, and a liquid crystal diphenylacetylene compound containing fluorine within the molecule.
A liquid crystal display element comprising:
A liquid crystal component which exhibits a cholesteric phase at room temperature, said liquid crystal component comprising:
A method for making a liquid crystal component which exhibits a cholesteric phase at room temperature, said method comprising the steps of:
