Abstract:
1. An organic electroluminescent apparatus comprising: a counter electrode; a plurality of light-emitting elements arranged in an element area, each of the light-emitting elements having a pixel electrode and an organic layer between the pixel electrode and the counter electrode; and a partition pattern separating the plurality of light-emitting elements from each other, wherein the partition pattern includes a first partition pattern having a plurality of first open portions and a second partition pattern having a plurality of second open portions and, in cross-sectional view, the second partition pattern being disposed closer to the counter electrode than the first partition pattern, wherein the organic layers are provided in the first open portions and in the second open portions, wherein in each of the first open portions, at least a portion of the corresponding pixel electrode is in contact with the corresponding organic layer, wherein in plan view, one of the first open portions is positioned in the corresponding second open portion; wherein all the first open portions have substantially the same planar dimensions; and wherein some of the second open portions provided in a peripheral region to the periphery of the element area have larger planar dimensions than those of other second open portions provided in a region closer to the center of the element area.
