A display plate 2 is formed with fine meshes by lattices, parallel lines, radial lines or their combinations in ground colours or background colours, and a shading plate 5 to be overlapped over the rear side of the display plate is also formed with the same or different meshes at the corresponding parts of said meshes. If the display plate and the shading plate are moved relatively, Moiré phenomena are caused in the meshes of the display plate in accompaniment with the position discrepancy between both meshes, so that blinking or winking are effected in the display plate. The display device may use flat plates moved by linkages (Figs 2, 3, not shown); alternatively, the device may use cooperating belts, cylinders or cones (for lampshades, Figs 7, 8, not shown) or use cooperating discs (for clockfaces, Figs 11, 12, not shown). <IMAGE> |
