Abstract
In the construction of an electrode matrix having m.multidot.n columns and rows for use, for example, with a liquid crystal display, the number of data electrodes to which independent signals are applied is Nn and the number of scanning electrodes to which independent signals are applied is m/N, N being the interval between elemental cell electrodes connected along the same data electrode. The data electrodes are formed on a baseplate with a layer of insulation covering the data electrodes. Elemental cell electrodes are formed on the insulating layer, and a limited number of openings through the insulating layer allow for an electrical connection between selected cell electrodes and the adjacent data electrode. Scanning electrodes may be formed on the insulating layer and/or on a facing baseplate. Two baseplates are in opposition to form a completed m.multidot.n matrix. Data electrodes on opposite plates overlap in the plan view, and a close spacing of individually controlled cell electrodes is achieved.
