Patent ID: 7452738

Claim:
A method of manufacturing an organic electroluminescent device, which, on a substrate, has a plurality of first electrodes, a light-emitting functional layer disposed to correspond to formation positions of the first electrodes, and a second electrode covering the light-emitting functional layer, the method of manufacturing an organic electroluminescent device comprising: forming a buffering layer that covers the second electrode; the forming of the buffering layer includes: coating a coating material containing a monomer/oligomer material and a curing agent under a vacuum atmosphere, without a solvent, and thermally curing the coating material so as to form the buffering layer; forming a gas barrier layer that covers the buffering layer; forming a partition that has a plurality of openings corresponding to the formation positions of the first electrodes; forming the light-emitting functional layer in the plurality of openings; and forming the second electrode that covers the partition and the light-emitting functional layer, the forming of the buffering layer forms the buffering layer to cover the second electrode and the partition.
