A display device for the electro-optical display of Indian numerals, wherein a plurality of display-active regions are disposed in patterns and electrically individually operated in combination, with predetermined display active regions of a pattern representing an individual numeral. In one embodiment, each display pattern for each Indian numeral consists of seven display-active regions disposed in the form of a frame which consists of an upper bar and a lower bar which both extend approximately horizontally, and a total of four side bars of approximately equal length, together with a planar display active region situated in the middle of the frame and whose length is approximately equal to its width, the side bars each have an end extending at least approximately in the direction of the planar display-active region. Other embodiments include an Indian numeric display employing as many as ten display-active regions.
