Design of polyimides for liquid crystal alignment films

Recent developments in the chemistry of polyimides (PIs) for liquid crystal (LC) alignment films are reviewed. Some important properties, such as low temperature curing, generation of pretilt angles, and electrical properties, are summarized with respect to the chemical structures of the PI materials. In addition, the future prospect of alignment films for enhanced LC display is also described. Copyright © 2000 John Wiley & Sons, Ltd.
