摘要： The present invention includes a method of preparing a dry deposited liquid-crystal alignment layer using one of a mechanical mask, photo-resist, UV treatment, and ridge and fringe field methods. The present invention further provides a multi-domain, wide viewing angle liquid-crystal display, comprising: a bottom substrate; a first transparent conductive layer; a top substrate; a color filter layer; a second transparent conductive layer; a first dry deposited liquid-crystal alignment layer; a second dry deposited liquid-crystal alignment layer, the second dry deposited liquid-crystal alignment layer being spaced adjacent to and facing the first dry deposited liquid-crystal alignment layer; spacers; and a liquid-crystal material. Each of the first alignment layer and the second alignment layer is divided into a plurality of pixels each having a boundary and at least two domains and the domains of each of the multi-domain, dry deposited liquid-crystal alignment layers is obtained by a method selected from the group consisting of: a mechanical mask, photo-resist, UV treatment, and ridge and fringe field. The multi-domain, wide viewing angle liquid-crystal display of the present invention can be operated in the in-plane switching mode, which results in reduced image sticking.

摘要： Multi-domain liquid crystal cells having twist angles less than 90 degrees, and LCDs containing such liquid crystal cells, are provided. Such liquid crystal cells are stable, particularly at zero and high fields, and provide wide viewing angles. Also provided are methods of using an adjustable particle beam in combination with a mask to generate multi-domains alignments. Such methods are useful for producing liquid crystal cells in general, and for producing the novel multi-domain low twist angle liquid crystal cells of the present invention in particular.

摘要： An apparatus for depositing and aligning an amorphous film in a single step, a method of forming an aligned film on a substrate in a single step by combining the deposition and alignment of an alignment layer into a single-step using ion beam processing and an amorphous film having an aligned atomic structure prepared by a method in which an aligned film is deposited and aligned in a single step are provided. The film is deposited and aligned in a single step by bombarding a substrate with an ion beam at a designated incident angle to simultaneously (a) deposit the film onto the substrate and (b) arrange an atomic structure of the film in at least one predetermined aligned direction.
