Abstract
An LCD (Liquid Crystal Display) including two substrates sandwiching an LC layer therebetween, and causing a plurality of different kinds of regions to coexist in the LC layer is disclosed. An electrode formed with an aperture is provided on at least one of the substrates. A second electrode is also provided on the same substrate as the above electrode in alignment with the electrode. A voltage higher than a voltage to be applied between the electrode with the aperture and a counter electrode facing it is applied between the second electrode and the counter electrode, thereby controlling the rising direction of LC molecules. The LCD is easy to produce and achieves a great viewing angle. In addition, the LC contains a polymer in order to fix the rising directions of the LC molecules.
