Abstract
There is provided a method of manufacturing an organic electroluminescence device including a plurality of light-emitting elements. The organic electroluminescence device includes a partition wall layer having a first partition wall layer with openings corresponding to the light-emitting elements and a second partition wall layer which is disposed on the first partition wall layer, the partition wall layer extends so as to follow the gap of the light-emitting elements, and has a groove on the top. The method of manufacturing includes forming the partition wall layer by forming the first partition wall layer and forming the second partition wall layer on the first partition wall layer such that the first partition wall layer is exposed at the bottom of the groove. The first partition wall layer is composed of an inorganic material, and the second partition wall layer is composed of an organic material.
