Abstract A single-domain, two-domain or four-domain homeotropic- or tilted homeotropic-alignment liquid crystal display device of either the transmissive-type or reflective-type having a high contrast ratio, a good display quality, and a high photo-stability (and a method of producing the same), includes a homeotropic- or tilted homeotropic-alignment layer which includes an oxide layer prepared by a single oblique evaporation of an activated oxide source. The angle between the evaporation direction and the substrate plane forms an angle from about +-20 DEG to about +-90 DEG , and the thickness of the oxide layer is from about 10 nm to about 200 nm. A method of homeotropic-alignment or tilted homeotropic-alignment of liquid crystals by a single oblique evaporation process is also provided.
