Abstract
Disclosed herein is an organic lighting apparatus that can reduce leakage current. The organic lighting apparatus includes a plurality of light-emitting portions, each of which has a first electrode including an electric current injection line, wherein the electric current injection line includes one or more fuse structures. With the electric current injection line including a fuse structure, when a short circuit occurs between first and second electrodes in a specific light-emitting portion, the fuse operates and prevents electric current from being injected into the short-circuited light-emitting portion, thereby making it possible to reduce leakage current.
