Patent ID: 7786667

Claim:
An organic electroluminescent element including a substrate, a first electrode, a partition wall next to the first electrode, an organic luminescent medium layer including at least one luminescent assist layer and organic luminescent layers on the first electrode, and a second electrode, wherein the organic luminescent layers emit different colors and are formed in adjacent pixels sectioned by the partition wall, wherein the organic luminescent medium layer is between the first electrode and the second electrode, wherein an area where the organic luminescent medium layer is between the first electrode and the second electrode is a light emitting area, wherein the luminescent assist layer is continuously formed from the light emitting area to a top face of the partition wall, wherein the organic luminescent layers are continuously formed from the light emitting area to the top face of the partition wall, and the organic luminescent layers overlap with the luminescent assist layer on the top face, and wherein a width of an overlapping portion of the organic luminescent layers over the top face of the partition wall is more than 1 μm and narrower than one-half of the partition wall.
