Abstract:
An organic light-emitting diode in accordance with the present invention includes: a reflective electrode; an organic layer formed on the reflective electrode; a transparent electrode formed on the organic layer; a transparent resin layer formed on the transparent electrode; and an encapsulation glass formed on the transparent resin layer. The organic layer includes a light-emitting point. Cone- or pyramid-shaped transparent resin structures are provided in the transparent resin layer in such a manner that each of the cone- or pyramid-shaped transparent resin structures splays from the transparent resin layer toward the encapsulation glass in a normal direction of the encapsulation glass. A refractive index of the transparent resin layer is 1.3 times or more to 1.6 times or less as high as that of the cone- or pyramid-shaped transparent resin structures.
