Two kinds of light sources 2 are composed of a fluorescent lamp for visible light source 4 and a fluorescent lamp for near UV light source 5. Changeovers between both fluorescent lamps 4, 5 are performed by a switch 6. In the decorative plate 3, patterns, etc., by a first and second color developing layers 7, 8 are separately formed on the plate by properly using a colorant developing by visible rays and a colorant developed by near UV rays.
