  • Patent number: 7786667
    Abstract: An organic electroluminescent element including a substrate, a first electrode, a partition wall next to the first electrode, an organic luminescent medium layer including an organic luminescent layer on the first electrode and second electrode is provided. The organic luminescent medium layer can be between the first electrode and the second electrode. An area where the organic luminescent medium layer is between the first electrode and the second electrode is a light emitting area. At least one layer among the organic luminescent medium layer is continuously formed from the light emitting area to a top face of the partition wall.

  • Publication number: 20070087645
    Abstract: A manufacturing method of a display device is disclosed. The display device can include: partition walls, a displaying part sectioned by the partition walls, a display function layer within the displaying part, and a substrate holding the partition walls, and the display function layer. The method can comprise forming at least one layer of the display function layer by an ink droplet supplied by transposition from an ink feed body, wherein the ink droplet is separated from the ink feed body after the ink droplet touches a region sectioned by the partition walls. After ink touched a region sectioned by partition walls, ink separates from ink feed body. Transposition of ink droplet forming the display layer is performed in this way. Therefore, even if a partition wall is not high, a partition wall can prevent ink droplet from scattering to other sections. Therefore, even if a partition wall does not include ink-repellent agent, a partition wall can prevent ink droplet from scattering to other sections.
