Abstract
The liquid crystal display device of this invention includes a plurality of picture element regions each defined by a first electrode provided on a face of a first substrate facing a liquid crystal layer and a second electrode provided on a second substrate so as to oppose the first electrode via the liquid crystal layer sandwiched therebetween. In each of the picture element regions, the first electrode has a plurality of openings and a solid portion, the liquid crystal layer is in a vertical orientation state when no voltage is applied between the first electrode and the second electrode, and when a voltage is applied between the first electrode and the second electrode, a plurality of liquid crystal domains each in a radially-inclined orientation state are respectively formed in the plurality of openings and the solid portion by inclined electrode fields generated at respective edge portions of the openings of the first electrode.
