Outline of Final Research Achievements

We have designed several new type photo-alignment polyimide films forming intermolecular charge transfer complexes, and developed the liquid crystal devices. Additionally, we designed an electronic circuit for evaluating the driving characteristics of the fabricated liquid crystal device in several driving modes. We systematically investigated liquid crystal device from material to driving electronic circuit.
