ABSTRACT:
A liquid crystal display includes a first substrate having a plurality of pixel areas. At least one pair of first and second protrusions is formed at each pixel area. A pixel electrode is formed at each pixel area. The pixel electrode has an opening pattern exposing the first protrusion while covering the second protrusion. A second substrate faces the first substrate. A common electrode is formed at the second substrate. Alternatively, the opening pattern and the protrusions may be formed in parallel.
