Abstract
An electromagnetic display device has a rotor rotatable between limiting positions and in said limiting positions to display contrasting faces in the viewing direction. The drive for the rotor uses a permanent magnet mounted on the rotor eccentrically of the rotary axis and a stator core mounted behind the rotor and on a line intersecting the rotor axis and parallel to the viewing direction.
