<p>A panel for displaying images in relief and/or moving images comprises a faceplate (23) comprising alternating opaque zones (24) and transparent zones (25), a backplate comprising a plurality of patterns (M,,) visible by transparency and organized according to an arrangement corresponding to that of the transparent zones of the other plate, said plates being separated by a transparent medium, so that depending on the axis of incidence of vision on the panel (1), an observer perceives one of several different images when the light (30) passes through the panel (1) from the rear. According to the invention, the faceplate and the backplate are embodied in the form of front (21) and rear (22) flexible sheets spaced apart (23), held essentially by edge regions in a relationship of mutual parallelism or quasi-parallelism, and in that the opaque zones of the front sheet and the patterns of the rear sheet are made by machine printing.</p> |
