| 4. An organic electroluminescent device, comprising:
a substrate;
a first electrode on the substrate;
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°;
an organic luminescence media layer on the first electrode partitioned off by the partition wall, the organic luminescence
media layer including an organic luminous layer; and
a second electrode on the organic luminous media layer opposed to the first electrode.
