ABSTRACT:
It is an object of the present invention to provide a display device that has a structure of an electrode where a residue of a transparent conductive film is not generated when a weak acid solution is used in etching, which is particularly appropriate for an electrode of a light-emitting element.A display device according to the present invention has an electrode that has a laminated structure of laminated transparent conductive films, and the electrode has a first transparent conductive film as the bottom layer, where no residue is generated when a weak acid solution is used in etching, and a second transparent conductive film as the top layer, which has a work function of 5.0 eV or more.
