    摘要： An embodiment of the present specification provides an organic light emitting device including: a first electrode; a second electrode provided opposite to the first electrode; one or more organic material layers provided between the first electrode and the second electrode; an auxiliary electrode provided in the first electrode; and a short circuit prevention layer provided between the first electrode and the auxiliary electrode, wherein the short circuit prevention layer has a resistance value which is greater at 50 or more ° C. than 25° C. The organic light emitting device controls the amount of leakage current when a short circuit defect occurs, thereby solving a problem where a device does not overall operate. The organic light emitting device stably operates without an increase in the amount of leakage current.
