The invention provides an organic electroluminescent device and a manufacturing method thereof, and a display apparatus. The method for manufacturing the organic electroluminescent device of the invention includes using the following to form at least one function layer: preparing a solution of a material of the function layer, and forming a liquid material layer for the function layer using the solution of the material of the function layer; performing a vacuum drying on the liquid material layer for the function layer to form function layer. In the invention, a relatively dense film is formed by performing a vacuum drying on the function layer, and the residual organic solvent is effectively removed to avoid the formation of defects, so that the film becomes smooth and dense, which increases the carrier mobility in the film and is advantageous to the transport and recombination of electrons and holes. |
