Abstract: A display device and a method for manufacturing the same are disclosed, in which a cathode electrode is not separated from an organic light emitting layer. The method for manufacturing a display device comprises the steps of forming pixels on a display area on a first substrate, forming an encapsulation film to cover the display area, attaching a protective film onto the encapsulation film, and removing the protective film. When attaching the protective film, the protective film includes a substrate layer and an adhesive layer formed at an edge area of at least one side of the substrate layer.

Abstract: Provided is an organic light emitting display device. The organic light emitting device includes: an organic light emitting element layer in an active area; and an encapsulation layer covering the organic light emitting element layer. The encapsulation layer includes one or more inorganic films and one or more organic films. The one or more inorganic films and the one or more organic films cover an entire active area and a part of an inactive area surrounding the active area. The one or more inorganic films are disposed only to a portion having a predetermined inward distance from an outermost periphery of the inactive area.
