ABSTRACT:
An object of the invention is to provide a method of introducing sightly tilting homeotropic orientation into a liquid crystal layer by oblique evaporation of inorganic material by one step, and a further object is to apply this method to provide a reliable liquid crystal electro-optical device or a liquid crystal light valve.
FIG. 1 shows an example of the method to introduce the slightly tilting homeotropic orientation into the liquid crystal layer by the one step of the oblique evaporation of the inorganic material. The orientation film is formed by the one step oblique evaporation. An incident angle is set from 45.degree. to 70.degree. relative to a parallel direction of the substrate, and a film thickness is set to 20 nm through 500 nm measured during the film deposition by a film thickness gage disposed at a vertical distance equal between the evaporation source and the substrate. The orientation film is used in the liquid crystal electro-optical device or the liquid crystal light valve.
