Abstract
Each pixel electrode of a liquid crystal display device is divided into a plurality of subpixel electrodes, which are separated by a gap from each other, and a control capacitor electrode is provided opposite at least one of the subpixel electrodes through a first insulating film. The control capacitor electrode has a region extending the entire length of the gap so that a drive voltage can be applied to liquid crystal in the gap. The control capacitor electrode forms a control capacitor connected in series with a liquid crystal capacitor formed by the above-said at least one subpixel electrode between it and a common electrode corresponding thereto. An additional capacitor electrode, which is opposite the said at least one subpixel electrode through a second insulating film, is formed, by which is formed an additional capacitor equivalently in parallel to the liquid crystal capacitor.
