摘要： Each pixel region includes first, second, third and fourth liquid crystal domains that come to have first, second, third and fourth predetermined tilt directions, respectively, in response to a voltage applied. The first, second, third and fourth directions are 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 are arranged in two columns and two rows so as to define a matrix pattern and to be adjacent to each other. An extended portion of a 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. A contact hole has been cut through an insulating layer, where there is a contact portion between a drain extension line and a first electrode, and is located in a part of the central opaque portion that is closer to the liquid crystal layer.

摘要： Each pixel region includes two subpixel regions, in which different voltages are applied to a liquid crystal layer with respect to a signal voltage supplied from a source bus line by way of TFTs. A first substrate includes a first electrode provided for the two subpixel regions. A second substrate includes a second electrode that faces the first electrode with a vertical alignment liquid crystal layer interposed. A liquid crystal capacitor is provided for each of these subpixel regions. Each subpixel region includes at least one liquid crystal domain that produces a dark area, which looks darker than a gray scale tone being presented for a viewer located in front of the device, inside of, and substantially parallel to, an edge portion of the first electrode. At least a part of the edge portion of the first electrode is arranged so as to overlap with a gate bus line and selectively shield at least a part of the dark area. Two TFTs associated with the two subpixel regions have substantially equal drain-gate capacitances Cgd, thus providing a VA mode liquid crystal display device that achieves good display quality.
