Abstract: The present invention attempts to improve coating processes used to produce organic EL devices, such as that an under layer is dissolved by a coating solution and efficiency and stability are poor. The present invention provides an organic EL device equipped with at least a first electrode formed on a substrate, a light emission medium layer containing at least an organic light emission layer, and a second electrode so formed as to face the first electrode so that the light emission medium layer can be sandwiched between the first electrode and the second electrode, wherein at least the organic light emission layer and a hole-transport layer adjacent to the organic light emission layer are contained in the light emission medium layer, and at least a low-molecular-weight hole-transport material and a matrix polymer having insulation properties and weight average molecular weight of about 200,000 to about 50,000,000 inclusive are contained in the hole-transport layer.

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.
