  • Patent number: 9508959
    Abstract: An organic Electro Luminescence device that equalizes heat generated in an organic EL element while preventing the intrusion of moisture. A light emitting element is covered with an inorganic sealing layer, an adhesive layer, an insulating resin film, and a metallic foil. The organic EL device includes a current carrying area located outside and along an edge of an emission area. A heat-conductive sealing stacked layer structure is formed in the current carrying area and includes the following layers in direct contact with each other in the following order: a first electrode layer extended from the emission area, auxiliary electrode layers having heat conductivity larger than that of the first electrode layer, the inorganic sealing layer, the adhesive layer, and a heat-conductive sealing layer. The heat-conductive sealing stacked layer structure having a linear shape is located near at least one side of a transparent substrate.

  • Patent number: 9373815
    Abstract: Provided is an organic EL device which can prevent invasion of moisture to an organic EL element. The organic EL device has an organic EL element in which a first electrode layer, a functional layer, and a second electrode layer are stacked in sequence on a transparent substrate having a planar expanse, and an inorganic sealing layer for sealing at least an emission area of the organic EL element. A soft adhesion layer is stacked directly onto the inorganic sealing layer with a planar expanse, and the soft adhesion layer is made of a resin, and has flexibility.
