Abstract

A liquid crystal display device has a pair of opposing substrates (1, 2) with liquid crystal material therebetween, having respectively segment electrodes (4, 11) and common electrodes (6, 7, 13). The common electrode (6) is formed over a segment electrode (4) on the substrate (1) and defines an effective area of the segment electrode. A display pattern is formed by applying between voltage to a combination of a segment electrode (4) and common electrode (6) on one substrate and a segment electrode (11) on the other. Common electrode (13) differs in voltage from electrodes (4) and (6) by less than threshold. Two different display modes are available by choice of substrate for the segment electrodes. Applications to a timepiece are discussed. <IMAGE>
