A display unit has a light source, an indicia bearing diffusion sheet or transparent having masked, transparent and translucent areas and a series of refractive layers are placed over the diffusion sheet. On the light being lit, and the light rays passed outwardly through the transparent or translucent areas and through the refractive layers, the indicia are each surrounded with a penumbra of light which gives a three dimensional effect to the display of the indicia.
