    • An organic light emitting device has a structure in which the penetration of harmful materials into an inner functional layer is blocked to prevent the degradation of the performance of the organic light emitting device and an organic electronic device includes such an organic light emitting device. The organic light emitting device includes an insulating substrate; a light emitting unit arranged on the insulating substrate and including a first electrode layer to inject holes, a second electrode layer to inject electrons, and an active layer interposed between the first and second electrode layers to emit light by recombining the holes and electrons; and a passivation layer including alternately arranged barrier layers and buffer layers to seal the light emitting unit from an external atmosphere, each barrier layer including at least one material selected from a group consisting of an activated metal oxide, an activated metal nitride, or an activated metal oxynitride, and each buffer layer being of a polymer organic material.
