  • Publication number: 20140021458
    Abstract: In an organic electro-luminescence display panel, an organic EL element is formed on a substrate. In the organic EL element, a first electrode formed on the substrate and has an electrode portion and a connection portion. A planarizing layer is formed around edges of the electrode portion. The planarizing layer planarizes a boundary with the first electrode. A partitioning wall has an aperture at an inside thereof. The partitioning wall is formed to be separated from the edges of the electrode portion toward the planarizing layer. A luminescent medium layer includes at least an organic luminescent layer and formed, in the aperture of the partitioning wall, on the first electrode and the planarizing layer. A second electrode is formed to be separated by the luminescent medium layer from the first electrode.
