PROBLEM TO BE SOLVED: To enhance quality by improving laser cutting accuracy, and eliminating restrictions on the color of a topcoat layer and the possibility of a burning phenomenon. SOLUTION: An undercoat layer 3, composed mainly of a mixture of metal powder and binder resin, is formed on the display plane side of a light transmissive molding 2, and a topcoat layer 4 is formed on the undercoat layer 3. Parts, corresponding to a display part, of the undercoat layer 3 and topcoat layer 4 are cut laser beam to form display parts 5, and a light source 7 is disposed on the opposite side of the molding 2 to the undercoat layer 3 and topcoat layer 4.
