ABSTRACT:
The alignment of liquid crystal materials in cells utilized for devices is significantly enhanced through the use of materials such as polyamides, polyimides, nylons, and polyesters. This expedient for alignment of liquid crystal materials is useful for nematic and cholesteric liquid crystals, but finds particularly advantageous use for aligning smectic liquid crystals.
