Abstract

A method of manufacturing a liquid crystal display device capable of easily giving a pre-tilt angle to a homeotropic orientation, the method having the steps of: forming a film of homeotropic orientation material on the surface of a substrate, the material being sensitive to ultraviolet ray and having a property of orientating liquid crystal molecules, on an average, vertically to the surface of the film; and applying ultraviolet rays to the film of homeotropic orientation material along a direction tilted from the normal to the surface of the film.
