Abstract:
1. A display device comprising: a pixel portion and a driver circuit portion, wherein each of the pixel portion and the driver circuit portion comprises: a semiconductor layer and a gate electrode with a gate insulating film interposed therebetween; a conductive layer formed on a same surface as the gate electrode, and extending in a direction perpendicular to a gate wiring, wherein a part of a pixel electrode overlaps the conductive layer; an insulating film formed over at least the gate electrode; and an electrode formed over the insulating film, and electrically connected to the semiconductor layer; an external input terminal portion, wherein the external input terminal portion comprises: a first wiring formed on the same surface as the gate electrode; a second wiring formed on a same surface as the electrode, and electrically connected to the first wiring through a contact hole opened in the insulating film; a transparent conductive film formed over the second wiring, and electrically connected to the second wiring; and a flexible printed circuit provided over the transparent conductive film, and electrically connected to the transparent conductive film.
