An exemplary embodiment of the present invention provides an organic light emitting diode, comprising a substrate, a first electrode, an organic material layer, and a second electrode, wherein a trench comprising a concave part and a convex part is provided on the substrate, the first electrode is provided on the substrate on which the trench is formed by being deposited, and an auxiliary electrode is provided on the first electrode. The organic light emitting diode according to the exemplary embodiment of the present invention may increase surface areas of the first electrode and the auxiliary electrode formed on the substrate, thereby implementing a low resistance electrode. In addition, since a line width of the electrode is not increased, it is possible to prevent a decrease of an opening ratio of the organic light emitting diode.
