-The invention relates to a seven-faced device for display and signalling by rotating prisms. -The subject of the invention is a device characterised in that it consists of a display-signalling body (2) presenting a façade delimiting a window (6) for exposing a message, and of a carousel (7) arranged in the said body so as selectively to present one of three faces, in line with the said window (6), one of which faces is neutral (28) and the other two of which are each defined by a conventional panel with side-by-side prisms (19, 20) mounted so as to rotate in synchronism, the said panel being capable of presenting three different messages, so that, in the said exposure window (6), one of six different messages or the said neutral face (28) can be displayed selectively. -Application to display, especially to roadsigns.
