Abstract:
1. A display device comprising: a semiconductor layer over a substrate, the semiconductor layer being provided outside of a pixel portion for displaying an image; a gate insulating film over the semiconductor layer; a gate line over and in contact with the gate insulating film; a first conductive film over and in contact with the gate insulating film, the first conductive film being provided outside of the pixel portion; a first interlayer insulating film over the gate line and the first conductive film; a second conductive film over the first interlayer insulating film, the second conductive film being provided outside of the pixel portion; a second interlayer insulating film over the second conductive film; a third conductive film over the second interlayer insulating film, the third conductive film being provided outside of the pixel portion; an electroluminescent layer over the second interlayer insulating film; and a fourth conductive film over the electroluminescent layer, wherein the second conductive film is electrically connected to the first conductive film and the semiconductor layer, and wherein the third conductive film overlaps with the first conductive film.
