Abstract:
1. A method for producing a liquid crystal display device comprising a pair of spaced and opposed substrates, a first electrode formed on one substrate, a second electrode formed on the other substrate, and liquid crystal molecules filled between said pair of substrates, comprising: providing alignment layer material exhibiting a vertically orienting property for a selected one of said substrates, aligning a mask having permeable portions and impermeable portions over a selected substrate, irradiating the mask with ultraviolet rays in a first inclined azimuthal direction; and simultaneously irradiating the mask from a second inclined azimuthal direction which is substantially 180 degrees different from the first inclined azimuthal direction, wherein the azimuthal direction of the alignment of liquid crystal molecules in a first region of the substrate is substantially 180 degrees different from the azimuthal direction of the alignment of liquid crystal molecules in a second region of the substrate.
