Abstract

An organic display panel having a high luminance, and including an organic light emitting element that includes a bottom electrode, a hole-injection layer, an organic light emitting layer, and a top electrode layered in the stated order on a substrate. The bottom electrode is composed of a material that is aluminum, silver, or an alloy including at least one of aluminum and silver. The hole-injection layer contains an oxide of a transition metal. The organic light emitting element further includes a mixed oxidized thin film interposed between and in contact with the bottom electrode and the hole-injection layer, the mixed oxidized thin film being composed of an oxidized mixture of the same material as the material in the bottom electrode and the same transition metal as the transition metal in the hole-injection layer.
