Abstract:
1. A continuous domain vertical alignment liquid crystal display, comprising: a first substrate and a second substrate, and liquid crystal molecules interposed therebetween, and a plurality of ridge-shaped first protrusions and a plurality of ridge-shaped second protrusions disposed at insides of the first substrate and the second substrate respectively, wherein each of the first protrusions is curved along a length thereof, each of the second protrusions is curved along a length thereof, and the curvature of each of the second protrusions corresponds to the curvature of a nearest one of the first protrusions; and a maximum width of each first protrusion is less than 10 microns, and a maximum width of each second protrusion is in the range from 5˜7.5 microns; wherein a path defining the curvature of each of the first and second protrusions satisfies the following equation: wherein x and y are Cartesian coordinates of any point along the path, ‘A’ is a constant number being the interval between each adjacent first protrusion and second protrusion, and ‘L’ is the length of the first protrusion or the second protrusion along the Y axis.
