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.

Organic EL device and method for manufacturing same

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.
