Abstract:
1. A liquid crystal display panel comprising: a pair of substrates and a liquid crystal layer interposed therebetween, the liquid crystal layer including liquid crystal molecules with negative dielectric anisotropy, wherein the pair of substrates each include an electrode, at least one of the pair of substrates includes a vertical alignment film and a photopolymerized polymer, the electrode on one of the pair of substrates provides pinwheel alignment of the liquid crystal molecules upon application of a voltage and is provided with first, second, third and fourth openings defined therein for surrounding a singular point of the pinwheel alignment and keeping the singular point within the electrode, each of the first, second, third and fourth openings in the electrode being completely laterally surrounded by the electrode: gate wirings and source wirings arranged perpendicularly to each other as viewed in plane, the openings surround the center of the electrode in which the openings are formed, and wherein the first and second openings make up a first pair of openings, and the third and fourth openings make up a second pair of openings, each of said openings having an elongated shape having its longitudinal direction aligned toward the center of the electrode, and wherein the longitudinal direction of the first pair of openings is aligned at an azimuth parallel to the gate wirings and the longitudinal direction of the second pair of openings is aligned at an azimuth parallel to the source wirings.
