The present invention relates to a flexible electroluminescent device and a method for manufacturing the same. A flexible electroluminescent device of the disclosed invention includes: a substrate where a display area including a number of pixel areas and a non-display area in the outer of the display area are defined; a switching thin film transistor and a driving thin film transistor formed at each pixel area on the substrate; an interlayer insulation film which is formed on the substrate including the switching thin film transistor and the driving thin film transistor, and exposes a drain electrode of the driving thin film transistor; a barrier pattern which is formed in the non-display area of the substrate, and surrounds the display area; a first electrode which is formed in each pixel area on the interlayer insulation film, and is connected to the drain electrode of the driving thin film transistor; a bank which is formed around each pixel area of the substrate including the first electrode and is formed in the non-display area; an organic electroluminescent layer which is formed on the first electrode separately according to each pixel area; a second electrode formed on the whole surface of the display area including the organic electroluminescent layer; a first passivation film which is formed on the whole surface of the substrate including the second electrode and on the upper part of a barrier pattern; an organic film d on the first passivation film of the display area; a second passivation film which is formed on the upper part of the organic film and the whole surface of the substrate, and on the first passivation film on the upper part of the barrier pattern; a protection film located as facing the substrate; and an adhesive agent which makes a panel state by bonding the substrate and the protection film by being intervened between the substrate and the protection film.
