ABSTRACT:
To provide an organic electroluminescent device which has a sealing structure including a casing and/or a sealing layer and which can be manufactured with high yield in such a manner that electrodes and other components are effectively prevented from being damaged due to stresses caused by the sealing layer and/or the electrodes. An organic electroluminescent device includes a substrate, a plurality of first electrodes, a partition structure having a plurality of openings located at positions corresponding to the first electrodes, organic functional layers each placed in the corresponding openings, a second electrode disposed over the partition structure and the organic functional layers, a sealing layer disposed over the second electrode, and a protective substrate, those components being disposed on or above the substrate. The organic electroluminescent device has a stress relief structure including a plurality of island-shaped members arranged along at least one part of outer ends of the partition structure.
