摘要： A method of manufacturing an organic light-emitting element. A first layer is formed above a substrate, and exhibits hole injection properties. A bank material layer is formed above the first layer using a bank material. Banks are formed by patterning the bank material layer, and forming a resin film on a surface of the first layer by attaching a portion of the bank material layer to the first layer, the banks defining apertures corresponding to light-emitters, the resin material being the same as the bank material. A functional layer is formed by applying ink to the apertures that contacts the resin film. The ink contains an organic material. The functional layer includes an organic light-emitting layer. A second layer is formed above the functional layer and exhibits electron injection properties. The hole injection properties of the first layer are then degraded by applying electrical power to an element structure.

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.
