    Abstract: A display device having a cell containing a liquid-crystal substance arranged between two opposing electrodes (3, 4, 5, 6). One of the opposing electrodes is subdivided into a plurality of selectively activatable adjacent display electrodes (4, 5, 6) forming bar graphs (9, 10, 11) while the other electrode is arranged opposite the display electrodes (4, 5, 6) as a common electrode (3).
