DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the nameplate according to the present invention will be described with reference to the drawings. Figure 1 shows entrance A with nameplate B
This is an example.

The nameplate B has a structure as shown in FIG. 2, for example. That is, 1 is electroluminescence (hereinafter simply referred to as EL) that emits light with low power consumption, 2 is a cover material, and 3 is a substrate. The EL 1 has a strip-shaped lead wire 4 as shown in the figure, and is sandwiched between the cover material 2 and the substrate 3.

The EL 1 is attached to the nameplate B and emits light when it is dark to improve visibility, thereby enhancing the presence of the nameplate B and facilitating confirmation of display. FIG. 2 shows an example in which the range of light emission to the outside is limited by using a transparent cover material 2 in which shaded portions other than the character portion of Tanaka are shielded, and the displayed surname is emitted in the dark. This is effective in facilitating the emphasis of the existence and the confirmation of the displayed contents.

The EL 1 may be anything that can be easily deformed and emits light with low power consumption. For example, the EL 1 emits light in response to an applied electric signal in the form of a thin and long sheet. Comprises a phosphor that is ground into fine particles and dispersed in a binder and dispersed in a thin layer between two plate or sheet electrodes, wherein at least one of the electrodes is substantially transparent. Things. When an electric signal is applied to the two electrodes, the fluorescent substance emits light, and a part of the light is transmitted to the outside through the substantially transparent electrode.

As an example of the structure of EL1, for example, a polyurea having excellent water resistance, durability and heat resistance is provided on an electroluminescent cathode composed of an anode, an organic compound film and a cathode on a substrate made of non-alkali glass. It is also possible to use a device having a protective film formed thereon and a device having a long life in which deterioration of the element due to corrosion of the cathode is prevented.

The EL1 is easy to deform and thin, and the wiring is simple, so that it is easy to assemble and attach. Further, since it has a sufficient amount of light emission with low power consumption, it has a low power consumption and the presence of a nameplate. Can be easily understood and the display can be easily understood. It should be noted that the outer side of the EL 1 may be coated with a fluorine film with a coating film or a film to enhance the acid resistance, waterproofness, and UV resistance.

The EL1 is thin and strip-shaped and freely deformable. For example, the EL1 has a driving voltage of 10 V or less and has a luminance of tens of thousands of cd / m ² , and has a structure such as an anode (ITO) / light-emitting layer / cathode. When the organic compound film has a single-layer structure of only a light emitting layer (comprising a polymer film or an oligomer film), the anode /
When an organic compound film such as a hole transport layer / light emitting layer / cathode or an anode / light emitting layer / electron transport layer / cathode has a two-layer structure of a hole transport layer and a light emitting layer, or a light emitting layer and an electron transport layer, There may be a three-layer structure of an anode / a hole transport layer / a light emitting layer / an electron transport layer / a cathode.

The hole transport layer of the organic compound film is represented by, for example, N, N'-diphenyl-N, N'-bis (3-methylphenyl) 1,1'-biphenyl4,4'-diamine. A thin film formed by vapor deposition of a low molecular dye having a hole transporting ability or a thin film formed by vapor deposition polymerization of a polymer film having a hole transporting molecular structure (polyamide, polyimide, polyazomethine, etc.) is used. Further, a low molecular dye having a hole transporting property may be deposited and dispersed in a polymer thin film.

The light emitting layer is made of, for example, a thin film formed by a vapor deposition method of a light emitting dye represented by 8-oxyquinolino aluminum complex (hereinafter referred to as Alq ₃ ) or a conjugated structure of stilbene, oxadiazole or the like. A thin film formed by depositing a polymer film (e.g., polyurea, polyimide, polyoxadiazole, etc.) by vapor deposition polymerization is used. Alternatively, a thin film in which a luminescent dye is deposited and dispersed in a polymer thin film may be used.

Further, as the electron transporting layer, for example, Al
depositing a thin film of q ₃ and an oxadiazole derivative is used,
Alternatively, a thin film of an anthraquinodimethane derivative or a diphenylquinone derivative can be used.

In the case where the EL1 has a two-layer structure as described above, for example, it is as shown in FIG. That is, a substrate 5 made of non-alkali glass, for example, an anode 6 made of an ITO film, a hole transport layer (or light-emitting layer) 7, a light-emitting layer (or electron transport layer) 8, and a cathode 9 made of, for example, an Mg-Ag alloy, It comprises a polyurea protective film 10 and an extraction electrode 11 made of Ag.

The electric power for emitting the EL1 is obtained by storing the electric power obtained by solar power generation in a battery or the like.
Light emission can be performed when necessary, and the use of the power-saving EL1 and solar power generation together can further promote improvement in economic efficiency.

The cover member 2 is, for example, in the form of a thin plate or a film, and its necessary portions are transparent or translucent, and portions other than characters are shielded from light. As the cover material 2, as a plate-like material, a thin plate-like member using a synthetic resin material such as an acrylic plate, or as a material when using a film,
