Abstract
The liquid crystal display device of this invention includes a first substrate, a second substrate, and a vertical alignment type liquid crystal layer including liquid crystal molecules having negative dielectric anisotropy disposed between the two substrates. In each of a plurality of picture-element regions, the liquid crystal layer has a plurality of liquid crystal regions different in the direction in which liquid crystal molecules tilt upon application of a voltage. At least one of the first and second substrates has a light-shield layer overlapping at least part of boundary region defined as regions separating the plurality of liquid crystal regions from each other. The part of the boundary region overlapping the light-shield layer is a region permitting liquid crystal molecules surrounding the region to tilt so that the ends of the liquid crystal molecules closer to the substrate having the light-shield layer go away from the region upon application of a voltage.
