A display element is adapted to be arranged together with other similar elements in rows and columns for displaying signs and comprises a housing (2), a surface element (6) connected to said housing and movable between two positions for displaying different surface information (4, 5), as well as a coil (9) optionally magnetisable in opposite directions, connected to the housing and adapted to actuate the surface element to occupy one or the other of said positions depending upon the direction of said magnetizing. The display element is adapted to be selected to magnetize the coil thereof by activating the column or row to which it belongs through lines interconnecting all display elements arranged in a column and a row, respectively. Means (18, 19) are integrated with the housing (2) and arranged to block magnetizing of the coil of the display element on activation of an interconnecting line (15 and 16, 17, respectively) belonging to the row of the element last mentioned if the interconnecting lines (16, 17 and 15, respectively) belonging to the column of this element are at the same time unactivated and conversely.
