摘要： A liquid crystal display device is provided which has a pair of substrates and a liquid crystal layer sandwiched between the pair of substrates, in which liquid crystal molecules are vertically aligned with respect to the substrates when no voltage is applied between the substrates and the liquid crystal molecules tilt in a plurality of directions to be almost parallel to the substrates by applying a voltage between the substrates. In the liquid crystal layer, when the voltage is applied, a proportion of a region where the liquid crystal molecules tilt in a direction of 0 degrees to 180 degrees is different from a proportion of a region where the liquid crystal molecules tilt in a direction of 180 degrees to 360 degrees with the angle being defined counterclockwise with the right direction on a screen being 0 degrees.

摘要： 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.
