PROBLEM TO BE SOLVED: To fix a plurality of boards each mounting display elements surely through a simple structure. SOLUTION: A board 11 mounting display elements is secured, at the opposite side edges thereof, between a pair of frames. Each side edge is fitted with an insulating material 12 and inserted into the groove 14 of a frame provided with an elastic member 15. The display element is provided on the same side of each board 11 while directing a specified direction. Since no screw is employed, fixing position can be selected freely and adjusted finely. When a plurality of boards are fixed, vertical interval can be set freely and the degree of freedom of fixing work is increased. Furthermore, screw hole and tapping work can be eliminated and the board can be fixed surely because it is not fixed with screws but fixed in a groove using an elastic member.
