Abstract
A VVA mode LCD has a liquid crystal (LC) layer of a negative dielectric anisotropy between lower and upper substrates. A pixel electrode is formed on the lower substrate. A color resin layer is formed on the upper substrate and has a V-shaped valley and jagged valleys, which are perpendicular to and shallower in depth than the V-shaped valley. A counter electrode is formed on the color resin layer and has a V-shaped valley and jagged valleys perpendicular to the V-shaped valleys. A first vertical orientation layer is formed between the pixel electrode and the LC layer. A second vertical orientation layer is formed between the counter electrode and the LC layer. First and second polarizers are attached to the outer and inner faces of the upper and lower substrates, respectively. The polarization axis of each intersects. The jagged valleys are provided to the V-shaped valleys via halftone exposure.
