Patent ID: 7098978

Claim:
A wide-viewing angle liquid crystal (LCD) comprising a plurality of pixel units, each comprising: a first substrate: and a second substrate disposed opposite each other with a liquid crystal layer interposed therebetween; first electrode formed on an interior of the first substrate: a first protrusion structure with a first pattern formed on the first electrode: a second electrode formed on an interior of the second substrate; and a second protrusion structure with a second pattern formed on the second electrode; wherein the first and second patterns constitute a third pattern with at least one intersection; wherein the first pattern comprises sequential combinations of a first line segment, a second line segment and a third line segment, the first and third line segments are parallel but not opposite to each other, and the second line segment is not parallel and not perpendicular to the first and third line segments; wherein the second pattern comprises sequential combinations of a fourth line segment, a fifth line segment and a sixth line segment, the fourth and sixth line segments are parallel but not opposite to each other, and the fifth line segment is not parallel and not perpendicular to the fourth and sixth line segments.
