Claims4
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, 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.
