Abstract:
1. A manufacturing method of organic electroluminescent device, the device including a substrate, a first electrode on the substrate, a partition wall adjacent to the first electrode, an organic luminescence media layer on the first electrode including an organic luminous layer, and a second electrode on the organic luminous media layer opposed to the first electrode, said method comprising: forming a pattern-shaped first electrode on a substrate, forming a partition wall of height of 0.5 μm -5 μm adjacent to the first electrode, the partition wall having a hem covering edges of the first electrode, the hem having a tapered configuration, and acroteric angle θ of the hem being less than 45°, and forming an organic luminous layer on the first electrode partitioned off by the partition wall by relief printing method, wherein the organic luminous layer is formed by using organic luminescence ink which dissolved organic luminescent material in a solvent.
