ABSTRACT:
A first substrate includes, on one side thereof that is closer to a liquid crystal layer, a picture element electrode provided for each picture element region, a switching element, and a bus line. A second substrate includes a counter electrode opposing the picture element electrode. The picture element electrode includes a plurality of openings and a solid portion that includes a plurality of unit solid portions. In each picture element region, the liquid crystal layer takes a vertical alignment in the absence of an applied voltage, and forms a plurality of liquid crystal domains, each of which takes a radially-inclined orientation, in the plurality of openings and the solid portion by inclined electric fields produced at respective edge portions of the plurality of openings of the picture element electrode in response to an applied voltage. In each picture element region, at least one of the plurality of openings of the picture element electrode that is located along the bus line and located between two adjacent ones of the plurality of unit solid portions is superposed on the bus line.
