Abstract: The present specification is drawn to an organic light emitting device and a method of manufacturing the same. The organic light emitting device includes a short circuit preventing layer provided on a substrate; a first electrode provided on the short circuit preventing layer, and including two or more conductive units provided to be separated from each other; a second electrode provided opposite to the first electrode; one or more organic material layers provided between the first electrode and the second electrode; and an auxiliary electrode. The short circuit preventing layer electrically connects the auxiliary electrode and the first electrode to control the quantity of leakage current even when a short-circuit defect occurs in the conductive unit.
