Abstract: Provided is an OLED device that includes an adhesive film having a network and a method for fabricating the same.The OLED device includes: a protective layer covering an organic light-emitting element on a substrate; a metal layer on the protective layer; and an adhesive film between the metal layer and the protective layer to attach the metal layer to the protective layer. The adhesive film includes a first adhesive layer composed of first polymers having a network structure, and a second adhesive layer composed of second polymers having a network structure and moisture absorbent. The network structure of the first polymers is bonded with the network structure of the second polymers at an interface between the first adhesive layer and the second adhesive layer.
