Abstract: One embodiment of the present invention relates to an organic light emitting diode, a method for manufacturing an organic light emitting diode, and a method for repairing an organic light emitting diode, the light emitting diode comprising at least one exposed part on an upper electrode which exposes an organic layer or a lower electrode, wherein the light emitting diode effectively prevents performance deterioration or operation failure of the light emitting diode due to leakage current by removing an electrical passage in an area prone to short circuit flaws.

Abstract: 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.
