摘要： A liquid crystal display device includes an alignment layer with constituent materials. The constituent materials have a stoichiometric relationship configured to provide a given pretilt angle. Liquid crystal material is provided in contact with the alignment layer. A method for forming an alignment layer for liquid crystal displays includes forming the alignment layer on a substrate by introducing an amount of material to adjust a stoichiometric ratio of constituent materials wherein the amount is determined to provide a given pretilt angle to the alignment layer. Ions are directed at the alignment layer to provide uniformity of the pretilt angle.

The surface is bombarded with ions, and reactive gas is introduced to the ion beam to saturate dangling bonds on the surface. Another method for preparing an alignment layer surface provides a surface on the alignment layer. The surface is bombarded with ions and quenched with a reactive component to saturate dangling bonds on the surface.

摘要： A method is disclosed for forming an alignment layer for use in a liquid crystal cell layer for use in a liquid crystal cell using an ion beam source that includes the steps of: (1) providing a substrate having a surface; (2) providing an ion beam source that emanates an ion beam; (3) providing a mask layer disposed between the substrate surface and the ion beam source. The mask layer has at least two openings disposed between the ion beam source and the substrate surface. The shape and position of the openings reduce the irregularity of the beam exposure in a border region on the surface of the substrate resulting from the ion beam source. The present invention may be used in conjunction with substrate treatment using multiple sweeps with a single ion beam source, or with a substrate treatment using a single sweep with multiple ion beam sources. Also disclosed is an apparatus for practicing the disclosed method.

摘要： A liquid crystal display device includes cell wall structure and a chiral nematic liquid crystal material. The cell wall structure and the liquid crystal cooperate to form focal conic and twisted planar textures that are stable in the absence of a field. A device applies an electric field to the liquid crystal for transforming at least a portion of the material to at least one of the focal conic and twisted planar textures. The liquid crystal material has a pitch length effective to reflect radiation having a wavelength in both the visible and the infrared ranges of the electromagnetic spectrum at intensity that is sufficient for viewing by an observer. One liquid crystal material may be disposed in a single region or two or more liquid crystal materials may be used, each in separate regions even without the infrared reflecting layer. One aspect of the invention is directed to a photolithography method for patterning a substrate of the display. The display may also have multicolor capabilities by including separate layers of at least two or three liquid crystal materials that reflect visible light. A full color stacked display may be produced with grey scale capabilities.
