Abstract
An edge lighted display in which light is transmitted through a translucent planar panel to be refracted by the presence of indicia, such as a crayon marking to provide a luminescent appearance. In the disclosed embodiment, the translucent panel which is made of synthetic resinous materials is provided with a thin coating on an outer surface thereof of a harden silicate material, whereby light rays pass in the plane of the junction between the outer surface of the panel and the inner surface of the coating prior to refraction for improved brilliance.
