動作の安定性に優れたものとなる。(Prior Art) Generally, an EL panel is made up of an EL element sealed with an insulating material and a back substrate, and this sealing is performed to ensure stable operation of the EL element over a long period of time. As shown in FIG. 2, a conventional EL panel has an EL element formed by laminating a transparent electrode 2, an EL thin film, and a back substrate 6 on a panel substrate 1 made of glass or the like, and a back substrate 10 processed into a concave shape. The structure is such that the EL element is sealed by sealing an insulating fluid 11 such as silicone oil into the gap created by the bonding. Note that the EL thin film is a double layer in which an EL light emitting layer 4 made of manganese-doped zinc sulfide, zinc selenide, etc. is sandwiched between a first dielectric layer 3 and a second dielectric layer 5 made of aluminum oxide, titanium oxide, etc. Those having an insulating structure have been developed, and thin-film EL panels obtained using such EL thin films have excellent dielectric strength, luminous efficiency, and operational stability.

ければならない点で繁雑なものであった。Incidentally, the filling of the insulating fluid 11 is carried out by bonding the back substrate 10 processed into an EL element, injecting the insulating fluid 11 from the injection hole 12 provided in the back substrate 10, and then filling the injection hole 12 with the insulating fluid 11. This is done by temporarily sealing the injection hole 12 with an aluminum piece 13, cleaning the area around the injection hole 12, and then adhering the sealing plate 14 to the injection hole 12 using an epoxy resin 15. However, the production of the above-mentioned EL panel is complicated in that it requires a step of filling an insulating fluid and processing a rear substrate.

However, in order to perform light-shielding coating on the back substrate to improve contrast,
The addition of a new process has made the EL panel manufacturing process even more complicated, and if EL panels that use colored insulating fluid are used in a stationary state for a long period of time, the dye will become unevenly distributed, making it difficult to There is a problem that a good light-shielding effect cannot be obtained, and the contrast decreases.

The element has a first curable insulating resin layer 7 covering the surface of the light emitting part of the EL element, and a second curable insulating resin layer 8 covering the entire surface of the resin layer, and a second curable insulating resin layer 8 covering the entire surface of the resin layer. A flat rear substrate 9 is disposed on a surface of the insulating resin layer 8 that is parallel to the panel substrate 1 . In the present invention, the light emitting part of the EL element is the first
The first insulating layer 3, EL light emitting layer 4, second insulating layer 5, and back electrode 6 shown in the figure are shown. At this time, the first curable insulating resin layer 7 acts as a protective layer for the EL element, and the second curable insulating resin layer 8 acts as a layer for bonding the back substrate 9. The curable insulating resin layer in the present invention is formed by applying a curable insulating material that can be cured by heating, irradiation with light, etc. using a screen printing method, roll coating method, etc. before curing. It can be formed by Further, the resin used to form the first curable insulating resin layer 7 is not particularly limited as long as it has excellent electrical insulation, does not generate by-products during curing, and has elasticity after curing. Examples include curable butyl rubber resins, styrene butadiene rubber resins, chloroprene rubber resins, fluorine resins, silicone resins, and the like. Among these, fluororesins and silicone resins are particularly preferred because they have excellent electrical properties after curing, can be used in a wide temperature range, and are chemically inert. Further, the resin used to form the second curable insulating resin layer is not particularly limited as long as it has excellent electrical insulation, moisture resistance, heat resistance, and adhesiveness, but for example, a curable fluorine-based resin Examples include resin, silicone resin, acrylic resin, and epoxy resin. Among these, epoxy resins are particularly preferably used because they have excellent electrical insulation and moisture resistance, exhibit sufficient adhesion to the rear substrate, and are low in cost.
本発明のＥＬパネルは、従来のＥＬパネルと比較して、

第１の硬化型絶縁性樹脂層はその硬化後に弾性を示し、
第２の硬化型絶縁性樹脂層で背面基板が接着されるので

くなる。Compared to conventional EL panels, the EL panel of the present invention has the following features:
Since the manufacturing process does not require an insulating fluid injection process or processing of the rear substrate, it can be easily obtained. Also,
The first curable insulating resin layer exhibits elasticity after curing,
Since the rear substrate is bonded with the second curable insulating resin layer, there is no problem of peeling of the rear substrate due to pressure, vibration, impact, or the like.
更に本発明のＥＬパネルは上記の第１及び／又は第２の

り従って、コントラストは向上する。Further, in the EL panel of the present invention, the first and/or second curable insulating resin layer has a light-shielding property, and this light-shielding property can be achieved by using a commercially available curable insulating resin having a light-blocking property, or by using a cured insulating resin layer. It is obtained by mixing a dye into the mold insulating resin layer. Since the curable resin layer in the EL panel of the present invention is cured, there is no reduction in the light shielding effect due to uneven distribution of the dye, and the contrast is improved.
