  • Publication number: 20050142382
    Abstract: An organic EL panel formed by interposing a resin layer between a sealing cover and a substrate on which an organic EL device section has been formed, making it possible to dispense with a hardening treatment of the resin layer, thereby avoiding an organic EL device deterioration possibly caused by the hardening treatment and at the same time simplifying the manufacturing process. A substrate on which an organic EL device section has been formed, is bonded with a sealing cover which if necessary is provided with a desiccating member, through the resin layer interposed therebetween. The resin layer is formed of a high molecular elastomer, making it possible to dispense with the hardening treatment of the resin layer.
