Abstract: Homeotropic liquid crystal displays, and methods for their production and use, are provided. The alignment layers of the subject displays have at least one alignment structure rising from a planar substrate. At least a portion of the wall has a bond anisotropy sufficient to align liquid crystal molecules substantially vertical to the planar substrate of the alignment layer. The subject displays find use in a variety of different applications, including in monitors for use in laptop computers, desktop computers, televisions, and the like.

Abstract: A method for producing a multi-domain alignment layer, as well as multi-domain alignment layers produced thereby and liquid crystal displays comprising the same, are provided. In the subject method, an alignment layer is produced on an alignment surface by directing an ion beam or ion beams at the surface at an angle not equal to 90°, so that the ions contact the surface at non-normal incidence. The substrate may be rotated or the ion beam(s) re-directed or the ion beam source moved so that the surface may be bombarded from different directions in different regions resulting in multiple alignment layer domains with differing alignment. In an alternative embodiment, two ion beams with different angles of incidence may be directed at the surface simultaneously or sequentially, thereby creating multiple alignment layer domains without need for rotation of the substrate. The resultant multi-domain alignment layers find use in liquid crystal display devices.
