Abstract:
The method of manufacturing an organic electroluminescence display device includes the steps of: forming an organic compound layer on a first electrode; forming a sacrificial layer soluble in a polar solvent on the organic compound layer; forming an intermediate layer formed of a water-soluble polymer on the sacrificial layer; patterning the sacrificial layer, the intermediate layer, and the organic compound layer; removing the intermediate layer and a layer formed thereon; and removing the sacrificial layer, in which the step of removing the sacrificial layer includes a step of performing a contacting step of bringing the sacrificial layer and the polar solvent into contact with each other a plurality of times.
