Provided are a substrate for an organic electronic device (OED), an organic electronic system, a method of manufacturing the system or substrate, and lighting. The substrate for an OED may be increased in durability by preventing penetration of an external material such as moisture or oxygen, and thus an organic electronic system having excellent light extraction efficiency may be formed. In addition, since the substrate may be stably attached to an encapsulating structure sealing the organic electronic system, the device may have excellent durability with respect to abrasion of an electrode layer or pressure applied from an external environment. In addition, surface hardness of an external terminal of the organic electronic system may be maintained at a suitable level.
