摘要： A pixel electrode is configured of one comb tooth portion and a contact portion whose width is widened from the end portion of the comb tooth portion in a first direction that is the extending direction of a scanning line. The width of the contact portion is not expanded in a direction opposite to the first direction, and the production of a domain is prevented. A picture signal line is bent in the direction in which the width of the contact portion of the pixel electrode is widened, so that the comb tooth portion of the pixel electrode can be disposed in the center between the picture signal lines, and the width of the contact portion can be formed in a sufficient width in the direction in which the picture signal line is bent. Thus, the contact margin of the pixel electrode can be provided.

摘要： In an LCD device having wall electrodes, four kinds of pixels are used that impart different alignment properties to the liquid crystal molecules. Specifically, the LC molecules are aligned such that: the LC molecules in first pixels twist clockwise and rise in a plus direction; the LC molecules in second pixels twist clockwise and rise in a minus direction; the LC molecules in third pixels twist counterclockwise and rise in the plus direction; and the LC molecules in fourth pixels twist counterclockwise and rise in the minus direction. The pixels of the same type are arranged in rows such that their long sides are adjacent to one another.
