Abstract: An organic light-emitting device is provided, which may include a substrate, an auxiliary electrode, an insulation layer, a first electrode, an organic layer, and a second electrode. The auxiliary electrode is provided on the substrate, and the insulation layer is applied on a portion of the surface of auxiliary electrode, wherein the other portion of the surface of the auxiliary electrode not being covered by the insulation layer forms a first contact portion. The first electrode is disposed on the substrate, the insulation layer, and the first contact portion, and electrically connects the auxiliary electrode via the first contact portion. The organic layer is formed on the first electrode, and the second electrode is disposed on the organic layer. The first electrode will form an open loop zone adjacent to foreign objects (e.g. particles), so that the first electrode and second electrode will not be short-circuited because the second electrode contacts the foreign objects in the open loop zone during the manufacturing process.
