50.2: Cholesteric Liquid Crystal Micro-Capsules with a Perpendicular Alignment Shell for Photo-Addressable Electronic Paper

Cholesteric liquid crystal micro-capsules (CLC-MCs) with a perpendicular alignment shell were investigated. The CLC-MC cell showed high contrast ratio up to 17:1, reflectance over 30% and uncolored white appearance in bright state. A photo-addressable electronic paper using the CLC-MC and an organic photoconductor was also demonstrated.

4.3: Novel Flexible Display using Ferroelectric Liquid‐Crystalline Polymer and Plastic Film Substrates

A novel flexible LCD has been developed by combining plastic film substrates with a FLCP mixture. Its optical response time has been improved by using a newly developed FLC polymer, particular polysiloxane typed structure. Good toughness against external shock has been achieved by arranging columns of UV-cure resin in the FLC layer. Manufacturing process of this LCD is simple and very unique. Coating the FLCP mixture on a plastic substrate and aligning molecules by bending method are used in the process. This LCD enables to realize a lightweight and flexible document reader called electric-paper by means of good memory effect and good mechanical durability.
