Abstract:
A display panel comprising a front and a rear and a plurality of layers therebetween including a substrate layer (2), wherein said plurality of layers further include a first, at least partially transparent, layer (8) and a second layer (12), said first and second layers being associated with the substrate layer having an obverse surface (4) and a reverse surface (10), wherein means (6) are provided for furnishing said substrate layer with a partially transparent tinted appearance, wherein said first layer comprises a coating comprising a transparent carrier in which are supported non-opaque particulate light-splitting materials, said materials being capable of causing light-splitting effects in light falling on the obverse surface from the front and wherein said second layer provides said at least selected areas rearwardly of said first layer which are of predetermined size and shape, such that the light-splitting effect caused by said particulate material in said first layer and visible in ambient light is suppressed by the passage of light of greater intensity than the ambient light from the rear of the panel so that the presence of said at least selected areas become visible from the front of the panel.
