Abstract
Disclosed is an organic light emitting diode, in which the light transmittance of a transparent cathode is improved, and which includes a substrate, a first electrode formed on the substrate, an organic layer formed on the first electrode, a second electrode formed on the organic layer, and a transparent layer formed at either one or both of a position between the organic layer and the second electrode and a position on the upper surface of the second electrode and including any one selected from among an oxide, a nitride, a salt and mixtures thereof, so that the formation of the transparent layer on the cathode results in increased light transmittance and decreased resistance, thereby improving electrical performance of products. A method of manufacturing the organic light emitting diode is also provided.
