PROBLEM TO BE SOLVED: To facilitate the fitting of an LED unit and to make the product low-cost and lightweight by assembling the LED display device by inserting the flat plate part of an LED unit into a groove part of a frame. SOLUTION: The LED display device 10 is formed fixedly in a framwork with two grooved frames 11, two support angle steel members 12 arranged at both ends, and fixing screws 13. The grooved frames 11 are formed of an aluminum material by extrusion molding etc. The width of the groove part of the grooved frame 11 is properly selected according to the thickness of the flat plate part 14a of the LED unit 14 so that slide insertion will be possible. The LED unit 14 is slid and inserted into the groove parts of the frames 11 and abut against anchor metals 15a each arranged at one end of the angle steel 12, so that it is fixed. The LED unit 14 is fixed by being clamped with the anchor metals 15a at both the ends and also fixed vertically by the groove parts of the frames 11. |
