ABSTRACT:
A display unit incorporating a light guiding plate. The light guiding plate formed of a transparent plate has on at least a part of its reverse side a reflection surface made of a minutely uneven surface. Immediately behind the light guiding plate disposed is a viewing object display on which an object to be viewed is drawn. The viewing object display is at least partially drawn with a visible light conversion reflection material capable of reflecting invisible light such as ultraviolet light in the form of visible light. The portion drawn with the visible light conversion reflection material is positioned correspondingly behind the reflection surface of the light guiding plate. A light source for emitting invisible light and a light source for emitting visible light are provided. At least the invisible light emitting source is located on at least a part of one lateral edge of the light guiding plate. Thus, the object to be viewed drawn with the visible light conversion reflection material can be selectively viewed through the light guiding plate, by receiving some invisible light which has passed the reflection surface.
