Abstract
The liquid crystal display device of the present invention includes a first substrate, a second substrate and a vertically aligned liquid crystal layer interposed between the first and second substrate. The device has a plurality of pixels each including a first electrode formed on the first substrate, a second electrode formed on the second substrate, and the liquid crystal layer interposed between the first and second electrode, and a shading region provided around the pixels. A plurality of supports for defining the thickness of the liquid crystal layer are placed regularly on the surface of the first or second substrate facing the liquid crystal layer in the shading region. The liquid crystal layer forms at least one liquid crystal domain exhibiting axisymmetric alignment when at least a predetermined voltage is applied, and the tilt direction of liquid crystal molecules in the at least one liquid crystal domain is defined with inclined sides of the plurality of supports.
