Patent ID: 8334954

Claim:
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; 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 between the first and second electrodes, 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, the first, second, third and fourth liquid crystal domains being arranged in two columns and two rows so as to define a matrix pattern and to be adjacent to each other, and wherein the first substrate further includes a TFT, a gate bus line, a source bus line, a drain extension line, a storage capacitor line, and an insulating layer that is arranged between the drain extension line and the first electrode, and wherein an extended portion of the storage capacitor line defines at least a part of a central opaque portion that selectively shields at least a part of a boundary area, where each of the first, second, third and fourth liquid crystal domains contacts with another one of the liquid crystal domains, from incoming light, and wherein a contact hole has been cut through the insulating layer, where there is a contact portion between the drain extension line and the first electrode, and is located in a part of the central opaque portion that is closer to the liquid crystal layer, and wherein the contact portion is located at the center of a cross boundary area, which is defined by the first, second, third and fourth liquid crystal domains that are arranged in two columns and two rows so as to define a matrix pattern.
