ABSTRACT:
A liquid crystal display device includes a plurality of picture element regions each including a first electrode provided on one side of a first substrate that is closer to 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 therebetween. The first electrode includes, in each picture element region, a solid portion including a plurality of unit solid portions, whereby the liquid crystal layer takes a substantially vertical alignment in the absence of an applied voltage between the first electrode and the second electrode, and forms a liquid crystal domain taking a radially-inclined orientation in a region corresponding to each unit solid portion of the first electrode by an inclined electric field produced around the unit solid portion in response to a voltage applied between the first electrode and the second electrode. Each unit solid portion includes four acute angle corner portions that are pointing respectively in upward, downward, leftward and rightward directions of a display plane.
