    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： We have found that liquid crystals can be aligned on a polyimide surface exposed to a low energy and neutral Argon ion beam. The energy of the incident ions were varied between 75 and 500 eV, the integrated current density from 100 .mu.A/cm.sup.2 to 500 mA/cm.sup.2, and the angle of incidence over which alignment was measured was between 10 and 20 degrees. The pretilt angle of the liquid crystals could be varied between 0 and 8 degrees, by controlling the processing conditions. Degradation of the polyimide, which leads to charge migration, can be avoided by operating at low accelerating voltages.

    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.
