Title:
LIQUID CRYSTAL DISPLAY ELEMENT, LIQUID CRYSTAL COMPOSITION, ALIGNING AGENT, METHOD FOR PRODUCING LIQUID CRYSTAL DISPLAY ELEMENT, AND USE OF LIQUID CRYSTAL COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2011/055643
Kind Code:
A1
Abstract:
Disclosed is a liquid crystal display element in which reactive monomers are blended into an aligning agent and polymerized by applying a voltage thereto. By the use of a specific aligning agent, a specific liquid crystal composition or a combination thereof, the liquid crystal display element can have excellent properties such as particularly suppressed image burn-in and reduced dissolution of unreacted monomers into a liquid crystal layer from the aligning agent. Also disclosed are: a liquid crystal composition; an aligning agent; a method for producing a liquid crystal display element; and use of the liquid crystal composition. Specifically 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.
