Abstract
A panel for a liquid crystal display (LCD) includes a substrate having a plurality of pixel areas defined thereon. A first alignment layer is formed on the substrate, the first alignment layer providing a first pretilt angle for a liquid crystal material. A plurality of spaced apart second alignment regions is formed on the first alignment layer, the second alignment regions providing a second pretilt angle for the liquid crystal material, respective second alignment regions being separated by a portion of the first alignment layer such that a respective pixel area is covered by the first alignment region and partially covered by a second alignment region. Portions of the first alignment layer and the second alignment regions covering respective adjacent pixel areas have grooves formed therein which are substantially aligned along respective first and second directions. The first and second directions preferably are perpendicular. The pixel areas may be rectangular, and the portion of a respective pixel area covered by a second alignment region may include approximately one-half of the pixel area. The approximately one-half of the pixel area may include a rectangular portion of the pixel area. Preferably, the second pretilt angle is greater than the first pretilt angle.
