Abstract
A liquid crystal display device comprises a sandwich structure of support plates with a layer of liquid crystal filled therebetween. One support plate has an array of thin film transistors and thin film capacitors both formed thereon, while the other support plate has a counter electrode formed thereon. One of a pair of electrodes of each thin film capacitor on the one support plate is offset from the counter electrode at any area other than area where they form an effective capacitance element, the other the area where they form an effective capacitance element, the other capacitor electrodes serving as display electrodes.
