1. 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.
