Patent attributes
A method for producing an organic electroluminescent device (100) includes the step of forming a driving circuit layer (2) on a substrate (1); the step of forming an inorganic protective layer (Pa) on the driving circuit layer; the step of forming an organic flattening layer (Pb) on the inorganic protective layer; the step of heating the organic flattening layer to a temperature higher than, or equal to, 200° C.; the step of forming an organic electroluminescent element layer (3) on the organic flattening layer after the step of heating; and, after the organic flattening layer is formed but before the organic flattening layer is heated, the step of forming an organic polymer film covering the organic flattening layer and the step of removing the organic polymer film.
