Abstract:
1. A display device comprising: a substrate; a source wiring line and a gate electrode formed over the substrate; a first insulating film having a first contact hole formed over the source wiring line and the gate electrode; a first amorphous semiconductor film containing a channel forming region formed over the first insulating film; second and third amorphous semiconductor films containing an impurity element formed over the first amorphous semiconductor film; a metal wiring line formed over the second amorphous semiconductor film wherein the metal wiring line electrically connects the second amorphous semiconductor film to the source wiring line through the first contact hole of the first insulating film; a second insulating film having a second contact hole formed over the source wiring line and the second and third amorphous semiconductor films; and a pixel electrode formed over the second insulating film and electrically connected to the third amorphous semiconductor film through the second contact hole of the second insulating film.
