Abstract:
1. A display device comprising: a substrate; a semiconductor film comprising a channel region formed over the substrate; a gate electrode adjacent to the channel region with a gate insulating film interposed therebetween, the gate insulating film having a first opening; a film comprising the same material as the gate electrode between the gate insulating film and the substrate; a first insulating film formed over the semiconductor film, the gate electrode and the film comprising the same material as the gate electrode, the first insulating film having a second opening and a third opening; a conductive layer contacting one of a source region and a drain region of the semiconductor film; a second insulating film comprising an organic resin and formed over the first insulating film, the second insulating film having a fourth opening and a fifth opening; and a transparent electrode formed over the second insulating film, the transparent electrode contacting the conductive layer via the second opening of the first insulating film and the fourth opening of the second insulating film, wherein the transparent electrode is electrically connected to the film comprising the same material as the gate electrode via the first opening of the gate insulating film, the third opening of the first insulating film and the fifth opening of the second insulating film, and wherein the fifth opening of the second insulating film overlaps the third opening of the first insulating film and the first opening of the gate insulating film.
