Abstract:
1. A liquid crystal display device comprising: a vertical alignment liquid crystal layer; a first substrate and a second substrate, which face each other with the liquid crystal layer interposed between them; a first electrode, which is arranged on the first substrate so as to face the liquid crystal layer; a second electrode, which is arranged on the second substrate so as to face the liquid crystal layer; and at least one alignment film, which is arranged in contact with the liquid crystal layer, wherein a pixel region includes first, second, third and fourth liquid crystal domains in which liquid crystal molecules are tilted in first, second, third and fourth directions, respectively, around the center of a plane, and approximately at the middle of the thickness, of the liquid crystal layer in response to a voltage applied, the first, second, third and fourth directions being defined such that an angle formed between any two of the four directions is approximately equal to an integral multiple of 90 degrees, and wherein the first liquid crystal domain is located close to at least a part of an edge of the first electrode, the part including a first edge portion in which an azimuthal direction that is perpendicular to the part and that points toward the inside of the first electrode defines an angle greater than 90 degrees with respect to the first direction, and wherein the second liquid crystal domain is located close to at least a part of another edge of the first electrode, the part including a second edge portion in which an azimuthal direction that is perpendicular to the part and that points toward the inside of the first electrode defines an angle greater than 90 degrees with respect to the second direction, and wherein the third liquid crystal domain is located close to at least a part of still another edge of the first electrode, the part including a third edge portion in which an azimuthal direction that is perpendicular to the part and that points toward the inside of the first electrode defines an angle greater than 90 degrees with respect to the third direction, and wherein the fourth liquid crystal domain is located close to at least a part of yet another edge of the first electrode, the part including a fourth edge portion in which an azimuthal direction that is perpendicular to the part and that points toward the inside of the first electrode defines an angle greater than 90 degrees with respect to the fourth direction, and wherein each of the first, second, third and fourth liquid crystal domains is adjacent to another one of the liquid crystal domains, and wherein either the first substrate or the second substrate includes an opaque member, which includes an opaque portion for shielding an intersection between a boundary area of each of the first, second, third and fourth liquid crystal domains, which is adjacent to another one of the liquid crystal domains, and one of the first, second, third and fourth edge portions from incoming light.
