It is made to emit light, and is widely used as a backlight for display means of various devices and a display unit such as a liquid crystal.

両側に発光層と透明電極とを形成するようにしていた。Here, of the two electrodes described above, as the counter electrode,
Aluminum foil is used, a light emitting layer consisting of a dielectric layer and a phosphor layer is laminated on the aluminum foil, and a transparent conductor such as ITO is vapor-deposited on the transparent film on the light emitting layer. The element is manufactured by bonding the transparent electrodes formed by the means. In this way, since the opaque aluminum foil is used on one side of the element, it is usually structured to emit light only on one side, and when forming an electroluminescent element that emits light on both sides. The light emitting layer and the transparent electrode are formed on both sides of the aluminum foil with the aluminum foil sandwiched therebetween.

There are inconveniences such as an increase in the thickness of the element and the necessity of providing three terminals, which complicates the structure.

ために、かかる方式を採用することはできないのが現状
である。However, in order to form an element that emits light from both sides with one light emitting layer, it is conceivable to form the counter electrode with a transparent member as with the transparent electrode. However, the light emitting layer including the dielectric layer and the phosphor layer is It is formed by applying and forming a paste, and its surface is rough. Therefore, if the transparent electrode formed by forming the electrode on the transparent film is directly stuck on the light emitting layer having such a rough surface, the two cannot be completely adhered to each other, and the air between them cannot be completely adhered. Therefore, the emission brightness is significantly reduced. Therefore, in order to bring this transparent electrode into close contact with the light emitting layer, the surface of the light emitting layer must be subjected to a smoothing treatment such as heat roller processing, and the light emitting layer is laminated on the transparent electrode having the above-mentioned structure. If the heat roller processing is performed in this state, there is a disadvantage that the vapor deposition portion of the transparent electrode is deteriorated or deteriorated, and therefore such a method cannot be adopted under the present circumstances.

It is an object of the present invention to provide a method of manufacturing the transparent electrode, which does not have a possibility of being deteriorated, has excellent adhesion between the light emitting layer and the counter transparent electrode, and has a simple manufacturing process.

It becomes possible to superimpose the light emitting layer and the counter transparent electrode in a state in which the light emitting layer and the counter transparent electrode are extremely well adhered to each other without performing the heat roller processing and the like, and there is no possibility that air intervenes therebetween. Therefore, when an electric field is applied between both electrodes, it becomes possible to emit light on both sides of the electrode, and the emission brightness becomes good.

It becomes possible to deposit a conductive member that forms an electrode such as ITO on the
For example, a member similar to the counter transparent electrode may be formed by coating on a synthetic resin film. Further, as the binder resin that disperses the conductive powder of the opposing transparent electrode, a fluorine-based binder resin that has a low water vapor transmission rate and a high dielectric constant is used, so that deterioration of the electroluminescent element due to moisture is prevented. It can be suppressed and durability can be improved.

防止することができるようになる。Next, as shown in FIG. 3, a counter transparent electrode 9 is laminated on the above-mentioned dielectric layer 7. The counter transparent electrode 9 is made of indium oxide, a mixture of indium oxide and tin, or the like. A transparent conductor powder dispersed in a binder resin is used. Thus, as the binder resin, a fluorine-based resin such as a copolymer of propylene hexafluoride and vinylidene fluoride having a high dielectric constant and a low water vapor permeability is used.
