P‐98: Red and White EL Materials Based on a New Fused Aromatic Ring

Excellent organic electroluminescent materials are needed to realize color EL devices with high performance. We have succeeded in realizing bright and efficient devices with long lifetime in red and white color regions, based on a new fused aromatic ring derivative.

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.
