Abstract:
1. An organic light emitting diode device, comprising: a substrate main body; a transparent electrode formed on the substrate main body; an organic emission layer formed on the transparent electrode; a cover electrode formed on the organic emission layer and made of a metal, the cover electrode including an oxide film formed on a first surface of the cover electrode opposite to a second surface of the cover electrode facing the organic emission layer, the oxide film being formed by oxidation of the metal of the first surface, the cover electrode having a thickness in a range of approximately 150 nm to approximately 5000 nm, the oxide film being thin in comparison with the metal of the cover electrode; and a sealant formed on the substrate main body to overlap an edge of the cover electrode and cover a side surface of the organic emission layer, the cover electrode and the sealant effectively suppressing the permeation of moisture or oxygen into the organic emission layer.
