2. Description of the Related Art Today, display devices such as signboards and display boards are known in which light sources are displayed using LEDs (light emitting diodes) instead of fluorescent lamps. Among these, the display panel and the light guide panel are incorporated into the front and back layers in the vertical and horizontal frames, and the LED is installed in any one of the vertical and horizontal frames so as to illuminate the edge of the light guide panel, and The display panel is illuminated by the light emitted from the light guide panel that receives the light emitted from the LED, and the display panel is configured to display. By incorporating this display device into the opening of a building such as a commercial building or a station building, it also saves energy. However, it has been proposed to increase the appeal of the display.
However, in the conventional display device incorporating the LED, when performing maintenance such as replacement of the LED incorporated in the frame, the display panel and the light guide panel are removed to expose the LED, so the frame itself is completely disassembled. Therefore, there is a problem that the maintenance work becomes complicated and time and labor are required.
Further, when replacing the panel itself, it is necessary to disassemble not only the panel but also the entire frame, and there is a problem that time and labor are similarly required.

  Therefore, a long board or panel with an LED attached is assembled so that it can be freely inserted and removed from the end of the frame, and at the time of maintenance, the board or panel is removed by removing the frame attached to the end of the frame incorporating the LED. There are known ones that can be taken out (see, for example, Patent Documents 1 and 2) and those that have an opening / closing door provided on a frame so that a substrate or panel can be taken out (for example, see Patent Document 3). ing.
