ABSTRACT:
It is an object of the present invention is to provide a light-emitting device in which high luminance can be obtained with low power consumption by improving the extraction efficiency. A light-emitting device of the invention comprises an insulating film, a plurality of first electrodes being in contact with the insulating film and formed on the insulating film to be in parallel, an electroluminescent layer formed over the plurality of first electrodes, and a plurality of second electrodes intersecting with the plurality of first electrodes and formed over the electroluminescent layer in parallel, wherein the insulating film contains nitrogen and silicon and the first electrodes contain a conductive transparent oxide material and silicon oxide.
