  • Manufacturing method for organic electroluminescent panel and organic electroluminescent panel manufactured using the same
    Patent number: 9059429
    Abstract: A simple manufacturing method for an organic electroluminescent panel in which organic electroluminescent elements are arranged and sealed by a sealing adhesive. The electroluminescent panel has excellent sealing properties and excellent durability as a result of the organic electroluminescent elements being adhered to one another by a heat-curable adhesive. The manufacturing method is for an organic electroluminescent panel in which at least a first electrode, an organic functional layer containing a light-emitting layer, an organic electroluminescent element having a second electrode, and a sealing substrate are bonded together on a substrate by the heat-curable adhesive.
    Type: Grant
