Abstract:
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.
