Abstract
The present invention focuses on a structure in which an auxiliary wiring for increasing the conductivity of an upper electrode is provided on the substrate side. The conductive auxiliary wiring of a light-emitting device is provided over a substrate, and an upper portion of the auxiliary wiring protrudes in a direction parallel to the substrate. Further, an EL layer formed in a region including a lower electrode layer and the auxiliary wiring is physically divided by the auxiliary wiring. An upper electrode layer formed in a manner similar to that of the lower electrode layer may be electrically connected to at least part of a side surface of the auxiliary wiring. Such an auxiliary wiring may be used in a lighting device and a display device.
