ABSTRACT:
A method of fabricating a liquid crystal display device including vertical alignment layers formed on the substrates. The alignment layer having a polymer realizing vertical alignment is formed on the substrate an unpolarized ultraviolet light is then irradiated in the oblique direction at an angle not more than 45 degrees with respect to the surface of the alignment layer. The ultraviolet light has an exposure energy of 30 to 120 mJ/cm2 per percent of the polymer content realizing the vertical alignment of the alignment layer. The liquid crystal can thus align substantially vertically to the surface of the alignment layer, with a pretilt, and such an alignment is realized by the irradiation of the ultraviolet light, without rubbing.
