The present invention discloses an organic electroluminescent display device and a display apparatus comprising a substrate, an organic electroluminescent pixel array disposed on the substrate, and a package film coated on an outside of the organic electroluminescent pixel array. The organic electroluminescent display device further comprises an optical film laminate body at a light output side thereof; and the optical film laminate body is a preformed integral component including a plurality of functional film layers. Since the optical film laminate body including the plurality of functional film layers can be bonded on organic electroluminescent display device by a single film-bonding process, it simplifies the manufacturing process, decreases the cost, reduces the thickness, and improves the flexibility of the organic electroluminescent display device. In addition, the present invention also discloses a display apparatus comprising the organic electroluminescent display device.
