Abstract

An alignment structure useful in a liquid crystal display device comprising a substrate having disposed thereon an oriented layer of a chromonic liquid crystalline material, wherein the chromonic liquid crystalline material comprises a chromonic material, a pre-tilt additive, and/or a cross-linking agent. The structure can be made by coating the chromonic liquid crystalline material onto the substrate and then drying or curing the coated substrate. The alignment structure can also include one or more polarizing dyes or other additives and can thus be made to perform polarizing, retarding and/or color filtering functions in addition to alignment and orientation functions. Liquid crystal displays containing such alignment structures and methods of making such displays are also described.
