摘要： An organic EL element has an anode, a cathode, a hole injection layer and at least one functional layer disposed between the anode and the cathode. The at least one functional layer contains an organic material. Holes are injected into the functional layer from the hole injection layer, which contains a tungsten oxide. A Ultraviolet Photoelectron Spectroscopy (UPS) spectrum obtained from a UPS measurement has a protrusion near a Fermi surface and within a region corresponding to a binding energy range lower than a top of the valence band. The tungsten oxide contained in the hole injection layer satisfies a condition, determined from an X-ray Photoelectronic Spectroscopy measurement, that a ratio in a number density of atoms other than tungsten and oxygen atoms to the tungsten atoms does not exceed approximately 0.83.

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.
