An improved mode of construction is provided for a display device of the kind comprising an array of triangular-section slats rotated in synchronism in 120 DEG steps to present repeatedly to view, in sequence, three compound display surfaces, each carrying a respective poster or the like. In embodiments of the invention, each slat has a respective bearing and driving module with a respective rotary member releasably drivingly engaging the slat and with a respective cam, driving the rotary member and driven in turn by a driving shaft, passing through the cams of the bearing and driving modules of all of the slats. The bearing and driving modules are received in a stack within a hollow extrusion which forms one side member of a frame of the display device. The opposite side member of the frame receives a stack of bearing members rotatably supporting the opposite ends of the respective slats.
