Is provided under the collar 1b, and further below the collar 1b.
A pair of electrode terminals consisting of c and the long hand 1d are provided. The long hand 1d is covered with the insulating film 1e from the flange 1b to a position beyond the tip of the short hand 1c.

FIG. 3 is a side cross-sectional view of the electrode plate 2, showing a surface insulating layer 2a, a positive electrode layer 2b, and an internal insulating layer 2 from the front side.
c, the negative electrode layer 2d and the back surface insulating layer 2e are stacked in this order. The front surface insulating layer 2a, the internal insulating layer 2c, and the back surface insulating layer 2e are made of an insulator, and the positive electrode layer 2b and the negative electrode layer 2d are made of a conductor.

Each of the layers 2a to 2e of the electrode plate 2 is made of a material into which the short hand 1c and the long hand 1d of the light emitting body 1 can be inserted. As shown in FIG. The insertion depth is regulated by the flange 1b, and the tip of the short hand 1c is connected to the plus electrode layer 2b, and the tip of the long hand 1d is connected to the minus electrode layer 2d. At this time, the long hand 1d penetrates the positive electrode layer 2b, but since the portion of the long hand 1d is covered with the insulating film 1e, the long hand 1d and the positive electrode layer 2b do not conduct.

When the luminous body 1 is inserted into the electrode plate 2 and the plus electrode layer 2b is connected to the plus terminal of a DC power supply (not shown) and the minus electrode layer 2d is connected to the minus terminal of the DC power supply, an electric The light emitting element built in the light emitting unit 1a emits light.

Thus, by inserting a plurality of luminous bodies 1 at desired positions of the electrode plate 2, desired characters, figures, etc. can be displayed on the electrode plate 2, and if unnecessary, the electrode plate 2 can be displayed. Since the luminous body 1 can be easily extracted from the display, the display content can be easily changed.
