LIQUID CRYSTAL DISPLAY ELEMENT AND PRODUCTION THEREOF

摘要

PURPOSE:To allow the application of a liquid crystal molecule oriented film with a uniform film thickness by forming the oriented film of a lyotropic liquid crystal polymer or thermotropic liquid crystal polymer having a mesogene group in the main chain or side chain. CONSTITUTION:The liquid crystal molecule oriented film is the water surface developed film of an org. high polymer and is constituted of the lyotropic liquid crystal polymer or thermotropic liquid crystal polymer having the mesogene group in the main chain or side chain. This high-polymer oriented film is crimped together with at lest a liquid crystal layer between a pair of electrode substrates at least one of which is light transparent. Problems such as generation of static electricity by a rubbing treatment, contamination of the boundary face of the oriented film and unequal display based on the nonuniformity in film thickness are eliminated in this way. Since the formation of the oriented film by the water surface development method is relatively easy and is highly mass productive, the easy mass production of the liquid crystal element is executed.
