A display device comprising a plurality of display members each having at least three display segments being pliably attached to or integral with one another to form an open ended tubular structure, with the walls being displaceable in a closed track defined thereby about an axis between consecutive display states in each of which one or two duty display segments lie on a corresponding one or two display plane(s) of the device. The axes of all display elements are parallel and the track of all elements is simultaneously displaceable. Each display element is associated with a displacement mechanism comprising at least one engagement unit engaging the duty display segment at its two side edges, and axially revolvable while continuously engaging an edge of the duty display segment so as to drag the track until a consecutive display segment comes to lie on the display plane to constitute a consecutive duty display segment.
