An illuminated advertising display device produces changing visual effects by placing a panel having a pattern of holes at the front of a light box with some of the holes defining alpha-numeric characters, and reciprocating behind the panel a shutter which has a pattern of transparent spots each of which registers with a hole in the panel at some point in the reciprocation of the shutter, with some of the spots registered simultaneously with all the holes that define the alpha-numeric characters. The panel has a forwardly facing reflective surface, and spaced forwardly of the panel is a light transmitting reflective sheet. If desired, the transparent spots may be tinted in several different colors.
