Abstract
A Liquid Crystal Display device has first and second transparent substrates with a liquid crystal material sealed therebetween; a centrally disposed optically active display region having a matrix of pixels and a first and second scanner, and a transparent common electrode formed on the inner surface of the first and second transparent substrates, respectively; and a power supply and data signal distribution region surrounding at least a portion of the optically active display region and near the first and second scanners. The power supply and data signal distribution region comprises (a) a groove, and (b) a plurality of parallel conductors, formed on the inner surface of the second and first transparent substrates, respectively, which conductors include a height extending into the groove to reduce each conductor's resistance. Conductor capacitance is reduced by (a) eliminating the transparent common electrode from the groove, and/or (b) providing an inert dielectric material or gas in the distribution region with a lower dielectric constant than the liquid crystal material.
