There packaging structure and packaging method of an organic electroluminescent device, the flexible display device

The present invention provides a package with a package structure and method of an organic electroluminescent device, the flexible display device, belonging to the field of organic electroluminescence. Wherein an encapsulation structure of an organic electroluminescent device comprising: a flexible substrate for supporting the organic electroluminescent device; the flexible substrate located on the organic electroluminescent device; covering the organic electroluminescence device the thin film encapsulation layer, the thin film encapsulation layer by a plurality of alternating first inorganic thin film and the organic polymer composition; the second inorganic thin film covering the nanowire structure of the thin film encapsulation layer. By aspect of the present invention can improve the water blocking capacity of the package, thereby effectively extending the life of the flexible OLED device.
