Abstract

Abstract A liquid crystal display has a liquid crystal layer supported by a pair of substrates therebetween; a transparent common electrode formed inside at least one of the substrates; and a plurality of transparent picture element electrodes respectively formed inside the at least one of the substrates and connected to each other through at least one active device; the transparent common electrode being disposed below one of the transparent picture element electrodes through an insulator layer; and the transparent common electrode being electrically connected to the transparent picture element electrodes adjacent to the one of the transparent picture element electrodes through the at least one active device. The transparent picture element electrodes are disposed such that the transparent picture element electrodes do not overlap the transparent common electrode.
