Abstract:
Disclosed is a liquid crystal display element which is composed of a pair of substrates (1) at least one of which is transparent. The liquid crystal display element comprises, between the pair of substrates, a transparent electrode (2), an aligning agent (3) that contains at least reactive monomers and/or oligomers (5), and a liquid crystal layer. The liquid crystal display element is characterized in that an alignment layer is obtained by polymerizing the reactive monomers or oligomers contained in the aligning agent, and the liquid crystal layer is composed of a liquid crystal composition that contains a compound (4) having at least one benzene ring in each molecule, said benzene ring containing at least one fluorine atom and being disubstituted by halogen atoms.
