A method of manufacturing an organic electroluminescence device including:

light-emitting elements including a first electrode, each of the light-emitting elements having second electrodes and an organic functional layer disposed between the first electrode and the corresponding one of the second electrodes, the organic functional layer including a luminescent layer;
a partition wall layer extending so as to follow a gap between the light-emitting elements;
and
an auxiliary line connected to one of the first and second electrodes so as to assist electrical conduction to the light-emitting elements,
the method comprising:
forming the partition wall layer;
forming a groove in the top of the partition wall layer;
subjecting the inside of the groove to liquid-affinity-imparting treatment;
subjecting at least the top of the partition wall layer to liquid-repellency-imparting treatment;
forming the auxiliary line to extend following the groove by using a liquid droplet ejection method to eject a conductive ink, in which a conductive material is dissolved or dispersed in a solvent, into the groove;
and
forming the one of the electrodes in contact with the auxiliary line.
