[Problems to be solved by the device]

 However, in the conventional guide display flat plate shown in FIG. 4, since the light emitting diode b ′ emits light of a point, a large number of light emitting diodes b ′ are required depending on the character, figure or symbol to be displayed. Moreover, since each light emitting diode b'has to be embedded in the flat plate body a ', the manufacturing cost and the material cost are high. In addition, the wiring such as the lead wire from the light emitting diode b'is complicated, and it takes a lot of time and labor for manufacturing and assembling. Moreover, rainwater or the like is likely to enter the electrical connection between the light emitting diode and the lead wire, which causes a short circuit.

In addition, in the display guide flat plate shown in FIG. 5, the fluorescent lamp b ″ occupies a large size, and the fluorescent lamp b ″ has to take a sufficient heat radiation space at the time of its light emission. Since the s ″ itself has a large volume, the thickness of the display guide flat plate itself increases. Therefore, when laying the display guide flat plate, it is necessary to bury the storage box s ″ deep in the ground, which is troublesome. In addition, it required a lot of installation space for transportation and storage. In addition, since the fluorescent lamp itself has a short life, maintenance and management such as replacement of parts are troublesome, which is uneconomical. Further, since a fluorescent lamp is used as the light emitting body, uneven light emission occurs on the light emitting surface. For this reason, there is an inconvenience that the characters and the like displayed on the translucent plate cannot be clearly recognized especially by the elderly and the low vision.

Therefore, the present invention can easily and reliably perform manufacturing and assembling, wiring processing, and the like without much time and labor, and can be made thin, and maintenance such as laying work and parts replacement can be performed.
