Abstract
Two electroluminescent substrates, each emitting light having different color, are laminated and bonded together with adhesive layer interposed therebetween. An insulation film such as an epoxy film is placed between two substrates and deformed into an adhesive layer under pressure and heat. The adhesive layer serves as a bonding material and a humidity-protection layer as well. Electrical connection between electrodes of the electroluminescent substrates and outside driving circuits is made at the same time two substrates are bonded by the adhesive layer by bonding wiring sheets together. To further improve the humidity-protection ability of the adhesive layer, the surface of the electroluminescent substrates may be covered by resin which is hardened by radiating ultraviolet light at the same time the insulation film is deformed into the adhesive layer. Thus, the electroluminescent display panel having two substrates can be manufactured in a simple and inexpensive manufacturing process.
