摘要： 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.

摘要： 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.

摘要： The organic photoelectric conversion element according to the invention has enhanced the light-absorbing property by incorporating two or more kinds of electron donating organic materials 4a and 4b in the photoelectric conversion region 14. With such measure, it has become possible to efficiently absorb the incident light and enhance the photoelectric conversion characteristic. In addition, a light-to-light conversion material 7 is incorporated in the photoelectric conversion region, too. With this measure, even the light of such a wavelength that an electron donating organic material cannot inherently absorb comes to be absorbed since the light-to-light conversion material 7 converts the wavelength, thus enabling the light to be utilized for carrier generation. Accordingly, an organic photoelectric conversion element with a high conversion efficiency can be obtained.

摘要： An organic electroluminescent (OEL) element includes a scanning electrode and a signal electrode, which crosses the scanning electrode at right angles, on a substrate. The signal electrodes are formed of N-layer electrodes laminated like steps, where respective layers are insulated from each other. The scanning electrodes are formed on the signal electrodes via an organic thin film layer. As a result, a display area is divided into sections corresponding to laminated numbers, and the divided each section is scanned independently. A duty ratio for driving the OEL element becomes large and less power consumption thus can be expected.
