Abstract

A display device comprises a frame 150 supporting in parallel spaced apart relationship a sheet of reflective glass 130 and a mirror 120. The mirror 120 is etched to define the outline of matter to be displayed. A lighting unit 170 which is encased in a housing 160 fixed to the frame 150 is located on the side of the mirror 120 remote from the sheet of reflective glass 130. Light from the lighting unit 170 projects the matter to be displayed onto the sheet of reflective glass 130 so that when the display is viewed from the side of the sheet of reflective glass 130 remote from the mirror 120 there is produced a multiple reflection of matter to be displayed. A proportion of the matter to be displayed is printed onto a light diffuser sheet 167 provided between the mirror 120 and the lighting unit 170. A photographically produced colour a transparency 166 of the remainder of the matter to be displayed is secured between the diffuser sheet 167 and the mirror 120.
