PROBLEM TO BE SOLVED: To reliably separate the illumination light sources from one another in a simple configuration not requiring special holders for them. SOLUTION: The illumination objects 22 are arranged on a panel 10. A circuit board 12 is disposed on the rear side of the panel 10 and illumination light sources 24 are mounted on this circuit board 12 to illuminate the objects 22. In order to prevent the light of those light sources 24 from crossing one another, barrier walls 26 are formed on the rear side of the panel 10 and an elastic sheet 30 is formed on the circuit board 12 on its surface facing the panel 10. The barrier walls 26 are positioned between the adjoining light sources 24 and project from the rear surface of the panel 10 toward the circuit board 12. The edges of those barrier walls 26 are in close contact with the elastic sheet 30 by deforming it. Thus the illumination light sources 24 are separated from one another. COPYRIGHT: (C)2009,JPO&INPIT
