TLDR
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 as discussed by the authors.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.read more

Patent
Liquid crystal cell with improved alignment
TL;DR: In a liquid crystal display device, the homogeneous alignment of twisted nematic liquid crystal molecules is accomplished by providing a first thin dielectric layer on the inner surfaces of each of the spaced apart glass plates covering complementary patterns of transparent electrode material.
Patent
Liquid crystal display incorporating positive and negative smectic material
TL;DR: In this article, a negative dielectric anisotropy smectic liquid layer is sandwiched between electroded plates treated to induce homeotropic alignment, application of an electric field turns the display from clear (black between crossed polarizers) to milky as the alignment changes from homeotropic towards homogeneous (metastable) degenerating to focal-conic.
