Abstract
There is provided a manufacturing method for an organic electroluminescent panel that includes an organic electroluminescent element for each sub-pixel. The manufacturing method includes an application step of recoating a first organic material layer and a second organic material layer, which include principal components common to each other, to manufacture the organic electroluminescent element. At the application step, after the first organic material layer is applied, an insolubilization process is performed for the first organic material layer to provide a change to a structure of molecules included in the first organic material layer, and the second organic material layer is applied to the first organic material layer after the insolubilization process is performed.
