Abstract
An LCD panel having a novel substrate structure, which has optical characteristics that extend the range of horizontal viewing angles with improved contrast ratio, and that extend range of vertical viewing angles with reduced grayscale inversion effect. In one aspect, the substrate structure includes an alignment layer provided with a plurality of first alignment grooves that are aligned at an angle close to an axis parallel to one edge of the display area. The angle may be 0.degree. or ranges from +20.degree. to -20.degree. relative to the edge of the display area. The LCD panel comprises two opposing substrate structures, with the alignment grooves orthogonal to each other.
