Abstract
The present invention discloses an organic electroluminescent display device and a display apparatus, wherein the organic electroluminescent display device employs an optical film lamination as a base substrate or a packaging cover plate, the optical film lamination includes a circular polarizer film, a water-oxygen resistant film and a color resistant film that are located on a supporting substrate, thus it has an antireflection function, a good water-oxygen resistance as well as a full-color display function, so that not only the problem of fussy process and high cost of an OLED display device caused by film application can be solved, but also the problem that the thickness of a flexible OLED display device is increased and thus the device is difficult to be rolled up due to film application is avoided; also, the OLED display device has the advantages of being lighter and thinner and having a better display effect, etc.
