Abstract:
1. A liquid crystal display device, comprising a first substrate, a second substrate, a liquid crystal layer provided between the first substrate and the second substrate, and a plurality of picture element regions for producing a display, wherein: the first substrate includes, on one side thereof that is closer to the liquid crystal layer, a picture element electrode provided for each of the plurality of picture element regions, a switching element electrically connected to the picture element electrode, and a bus line including a gate bus line and a source bus line that are electrically connected to the switching element; the second substrate includes a counter substrate opposing the picture element electrode via the liquid crystal layer; the picture element electrode includes a plurality of openings and a solid portion that includes a plurality of unit solid portions; in each of the plurality of picture element regions, the liquid crystal layer takes a vertical alignment in the absence of an applied voltage between the picture element electrode and the counter electrode, and forms a plurality of liquid crystal domains 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 a voltage applied between the picture element electrode and the counter electrode, each of the plurality of liquid crystal domains taking a radially-inclined orientation, and an orientation of each of the plurality of liquid crystal domains changing according to the applied voltage, thereby producing a display; and in each of the plurality of picture element regions, 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 overlaps the bus line.
