  • Patent number: 8310146
    Abstract: This invention provides an organic electroluminescent element that has a thin and compact sealing structure and is excellent in heat resistance in sealing, particularly a high-brightness organic electroluminescent element comprising a phosphorescence emitting substance, and a liquid crystal display device and lighting equipment using the same. The organic electroluminescent element comprises a substrate and a first electrode, one or more organic layers including a luminescent layer, and a second electrode provided on the substrate. An adhesive layer is disposed on the whole area of a light emitting surface and remote from the light takeout side in the organic electroluminescent element, and a flexible film having a barrier film is applied thereto to form the light emitting surface.

  • Publication number: 20110315977
    Abstract: Provided is an organic electronic panel wherein warping (deformation) of a metal member is suppressed when the metal member is used as a packaging board, an electrical short-circuit due to the warping is eliminated, and generation of light emission failure and deterioration of power generating performance are eliminated. In the organic electronic panel, the packaging board is composed of a metal foil, and a polymer film is laminated on the metal foil surface on the reverse side of the side having the adhesive layer. The thickness of the polymer film is not more than that of the metal foil, and heat is applied at the time of bonding/laminating the packaging board or at the time of hardening the adhesive layer.

  • Patent number: 8080277
    Abstract: A method of forming an organic compound layer for producing organic EL element exhibiting high quality and high productivity without increasing cost; a relevant process for producing an organic EL element. There is provided a method of forming an organic compound layer of organic EL element using production apparatus including supply section, coating•drying section and recovery section, characterized in that flexible band substrate (A) having an anode layer in roll form is fed to the supply section; the production apparatus has at least one unit coating•drying section, the unit containing coating section capable of forming coating film for formation of organic compound later under atmospheric pressure by wet applicator and drying section; and at least one organic compound layer is formed on the anode layer to obtain flexible band substrate (B), which is wound on a core to form a roll in the recovery section.
