The disclosure provides an encapsulation method and an encapsulating structure of an organic electroluminescent device, and a display apparatus. The encapsulation method of an organic electroluminescent device includes: providing a flexible substrate; forming an electrode layer on the flexible substrate; sequentially forming an inorganic layer on a surface of the electrode layer and an organic layer stacked on a surface of the inorganic layer, and a multilayer structure is formed by the inorganic layer and the organic layer alternately stacked with each other, the inorganic layer is formed by a chemical deposition method, and the organic layer is formed by printing; and dry etching the multilayer structure to form a thin film encapsulation layer. The disclosure has the advantages of low production cost and can solve the problems of high material cost, difficult maintenance, and poor film quality caused by the need of using the mask in the prior art.
