PCT No. PCT/HU94/00023 Sec. 371 Date Feb. 29, 1996 Sec. 102(e) Date Feb. 29, 1996 PCT Filed Jun. 24, 1994 PCT Pub. No. WO95/01620 PCT Pub. Date Jan. 12, 1995A signal display device with passive components is disclosed, in particular for displaying characters which consist of a plurality of matrix-arranged picture elements. The device has an information-carrying base plate, suitable in particular for color information. Display elements made of generally cylindrical bodies can preferably swivel around an axis that coincides with their centroidal axis. Said display elements are provided with at least one signal display surface which can swivel in the direction of the information display surface of the base plate and which is suitable for carrying information, preferably information that differs from the information carried by the base plate. The invention is characterized in that the display elements are provided with three such parts which are mutually offset in the direction of their axes and of which two front faces are arranged perpendicularly to the axis and are secured to each other forming a single piece with the signal display surface. Magnetic bodies having faces with a section perpendicular to the axis and preferably a cross-section perpendicular to the same axis have axial dimensions which are substantially smaller than the distance between the faces and which reach at the most half the distance between the faces. Said magnetic bodies ar arranged in the vicinity of the one or the other face of the display elements, preferably on one or the other face of the display elements.
