Description of the invention (10) (Please read the note on the back? Matters before filling out this page) Lamination between thin films that are not highly barrier to each other 'or have When laminating a highly gas-barrier film and a low-gas barrier film, the carbon dioxide gas generated by such a hydroxy-cyanate-based two-liquid curing urethane-based adhesive will Escape from both sides or one side of the adhesive layer. However, in the case of laminating the films which are mutually highly gas barrier with this kind of adhesive, because the carbon dioxide gas has nowhere to escape, the foaming phenomenon will spread to the entire adhesive layer, and the Foam dishes have become the cause of poor appearance. Not only that, because the cohesive strength of the adhesive is reduced due to foaming, the most important adhesive strength is reduced. In addition, although the detailed reason is unknown, the fact that the gas barrier property itself is also reduced is known. On the other hand, if the adhesive contains a polyurethane resin and a polyepoxide compound having an amine group, it will not occur due to the hardening caused by the reaction between the amine group and the epoxy group, including such carbon dioxide gas. Foaming of the adhesive layer occurred. Therefore, in the production of the laminated body of the present invention, which is bonded to the same films having particularly high gas barrier properties, an adhesive containing a polyurethane resin having an amine group and a polyepoxide compound is used.

Description of the invention (17 The lamination method of the laminated body and hot-melt plastic of the present invention is preferably made with an adhesive. Film-like dry-laminating method for hot-melt plastics. However, it is also known that conventionally well-known adhesives can be laminated by melting the hot-melt plastics and forming a thin film. Adhesives, such as two-component hardened urethane-based adhesives, but it is best to use adhesives containing polyurethane resins and polyepoxides with the aforementioned amine groups. In some cases, corona treatment, plasma treatment, and flame treatment may be applied to the surface of the heat-fusible plastic film (ie, the adhesive surface) before lamination. The laminated body and the heat-adhesion of the present invention The lamination of plastics can be carried out in the same way as the lamination of the surface-treated PET film and the surface-treated pVA previously described. Furthermore, it may be advisable to place between the films, or between heat-fusible plastic and EL elements. Interlayer laminated hydrophilic films of nylon, polyvinyl alcohol, celluloid, ethylene vinyl alcohol copolymer saponification, etc. Especially in the case of laminated nylon, trapped moisture is trapped to improve the prevention of deterioration of the display element The effect is very ideal. By using the laminated body of the present invention, a display element package structure (100) as shown in FIG. 1 can be produced. Specifically, it can be formed on the barrier substrate (8). The light-emitting surface can be arranged outside the barrier substrate (that is, the layered body of the present invention can be laminated in the light-emitting direction of the light-emitting element). The display is formed by stacking inorganic EL elements, organic elements, and liquid crystal display elements.

Moreover, it is also ideal to use the laminated body of the present invention as a barrier substrate. Barrier properties around (around) the display element The method of adhesion between the substrate and the laminated body is not limited. Generally, thermal lamination or thermal compression can be used, but it is also advisable to use an adhesive for adhesion. In this case, the area of the multilayer body and the barrier substrate must be larger than the area of the display element. This is because the area of the laminated body or the barrier substrate is smaller than the area of the display element. The periphery of the display element will not be completely adhered and the display element is exposed from the laminated body so that packaging cannot be performed. The laminated body of the present invention is particularly suitable for encapsulation of an EL element because it has a very high water vapor barrier property which is not available in conventional thin films. The inorganic EL element consists of a light-emitting layer containing zinc sulfide (element symbol 4 in the figure), an insulating layer (5) using barium titanate, and a transparent conductive film (3) with a transparent electrode layer on the surface of IT0 ^ ), Which is formed using a backside film-forming electrode layer (6) such as carbon and a moisture-absorbing layer (not shown), but it is not particularly limited. ^ 'Organic EL elements form a layer of bite between the anode and cathode' paper size applies to Chinese National Standard (CNS) A4 (210 X 297 mm) 3Π31T (Please read the note on the back before filling in this (Page) I-------- r I--Order --------- line. 1 ^ 1 丨 '-
