  • Patent number: 8642360
    Abstract: A resin material layer including photosensitive resin material is formed on an interlayer on an underlayer. By partially exposing and developing the resin material layer using developer in which the resin material layer and the interlayer are soluble, an uncured portion of the resin material layer is removed to form an opening penetrating to the interlayer, and the developer infiltrates into the interlayer via the opening to remove at least surfaces of first and second portions of the interlayer. The first portion corresponds to the opening. The second portion surrounds the first portion. Each bank is formed by heating a remaining portion of the resin material layer to soften an overhanging portion above a space formed by the surface of the second portion being removed, so that the overhanging portion flows downward to fill the space, cover an exposed portion of the interlayer, and contact the underlayer or the interlayer.

  • Publication number: 20130313543
    Abstract: Provided is an organic EL element which withstands mass production of organic EL display panels, and promises driving at a low voltage and high luminous efficiency due to excellent hole-injection efficiency. Specifically, an organic EL element is formed by sequentially laminating an anode, a hole injection layer, a buffer layer, a light-emitting layer, and a cathode on one surface of a substrate. The hole injection layer is a at least 2 nm thick tungsten oxide layer formed under predetermined film forming conditions, and includes an occupied energy level that is 1.8 eV to 3.6 eV lower than a lowest energy level of a valence band of the hole injection layer in terms of a binding energy. This reduces the hole injection barrier between the anode and the hole injection layer and the hole injection barrier between the hole injection layer and the buffer layer.
