A phosphor layer 6 made of zinc sulfide or the like laminated above the outlet 2a; and electrodes 7 connected to the lower electrode layer 2 and the upper electrode layer 5, respectively. The writing unit 8 emits light by writing with an aqueous solvent over the lower electrode layer bulging portion 2a and above the upper electrode layer 5 with a solvent writing tool. That is, as is well known, the electroluminescent lamp used in the writing sheet of the electroluminescent lamp of the present invention has a back insulating layer 1 and a lower electrode layer 2.
And an intermediate insulating layer 3, an upper electrode layer 5, a phosphor layer 6, and the like, which are laminated and have flexibility. The one shown in FIG. 1 is exaggerated, Has an overall thickness of about 0.2 mm and emits an anti-glare light that is easy on the eyes. In addition, the basic colors are blue, green, purple, and white. Is used to make it possible to develop other multicolors. The back insulating layer 1 is formed of an insulating synthetic resin such as polyester in a sheet shape, and has a lower electrode layer 2 to be described later laminated on the upper surface. Next, the lower electrode layer 2 is made of silver ink or the like, and is laminated on the upper surface of the back insulating layer 1 by means of silk printing or the like. The lower electrode layer swelling portion 2a is regularly swelled, and in the embodiment of the lower electrode layer swelling portion 2a shown in FIG. 1 or FIG. The shape is not particularly limited,
In the embodiment, the diameter is about 0.5 mm to 1 mm. Next, the intermediate insulating layer 3 insulates the lower electrode layer 2 from the upper electrode layer 5, and is laminated on the upper surface of the lower electrode layer 2 in a sheet shape using an insulating synthetic resin or the like. However, a large number of columnar lower electrode layer swelling portions 2a which regularly swell on the upper surface of the lower electrode layer 2 penetrate upward. Further, as shown in FIGS. 1 and 4, the upper electrode layer 5 is laminated on the upper surface of the intermediate insulating layer 3, and the top surface of the lower electrode layer bulging portion 2a and the upper electrode layer 5 The upper surface of the lower electrode layer is made to be flush with the outer periphery of each of the plurality of lower electrode layer bulging portions 2a, and the lower electrode layer bulging portion 2a is laminated. Outgoing part 2a

Further, the phosphor layer 6 is made of zinc sulfide or the like, and is laminated so as to cover the upper surface of the writing sheet. As shown in FIG. 4 and the lower electrode layer 2 are laminated so as to cover the upper part of the lower electrode layer bulging portion 2a. The electrode 7 is connected to the lower electrode layer 2 and the upper electrode layer 5 to supply power from a power supply. The power supply may be a commercial power supply or a battery, and may be an inverter, a switch, or the like.
They are connected by a power cord or the like via connectors and terminals. The writing section 8 is an arbitrary figure or character drawn with an aqueous solvent such as water or an aqueous ink by a felt-shaped pen tip protruding from the tip of an aqueous solvent writing instrument. Are written so as to straddle over the lower electrode layer bulging portion 2a and above the upper electrode layer 5. For example, by attaching an aqueous solvent such as water as the writing portion 8 to the upper surface of the phosphor layer 6 as an arbitrary figure or character, the lower electrode layer 2, the phosphor layer 6, and the writing portion 8 are energized. An electrolysis field is formed in the writing section 8, the phosphor layer 6, and the upper electrode layer 5, and the writing section 8 shines when the phosphor layer 6 emits light. Next, the power supply and the lower electrode layer 2 are applied by the electrode 7.

The writing unit 8 is formed by writing a desired arbitrary figure or character. The writing sheet of the electroluminescent lamp of the present invention has the same color as the light emitted by the phosphor layer 6 when the writing section 8 is written with transparent water using a water pen to write any figure or character. When the water evaporates completely after a lapse of time, the written portion 8 that has been written disappears, and another arbitrary figure or character can be written on the phosphor layer 6 again. In addition, the writing portion 8 written with a colored water-based oil-based ink of a water-based oil-based pen has a writing portion 8 in which the color of the water-based oil-based ink and the color of the light emitting phosphor layer 6 are mixed. Yes, the writing portion 8 written with the water-based oil-based ink is in a state where the color of the water-based oil-based ink is left as it is, even when the water vaporizes after elapse of time,
Incidentally, among the oil-based inks of the oil-based pen, those containing no alcohol are inappropriate. The writing sheet of the electroluminescent lamp of the present invention has the above-mentioned structure, and the upper surface of the lower electrode layer bulging portion is flush with the upper surface of the lower electrode layer bulging portion. An upper electrode layer is laminated by providing an interval between the outer periphery of the lower electrode layer swelling portion and the lower electrode layer swelling portion of the lower electrode layer with an aqueous solvent using an aqueous solvent writing tool on the upper surface of the phosphor layer. By writing so as to straddle the upper part and the upper part of the upper electrode layer, an electric field is generated in the lower electrode layer, the phosphor layer and the writing part, and the writing part, the phosphor layer and the upper electrode layer, and the phosphor layer is formed. Is a unique one that illuminates the writing area by emitting light.It is unique to make it look as if it is emitting light by itself, and furthermore, the electrode for voltage driving can be freely connected, so it can be cut into the desired size and shape To be used in large sizes.
