Patent ID: 7646441

Claim:
An electro-optical display device comprising: a first substrate having an insulating surface; at least one thin film transistor formed over said first substrate, said thin film transistor comprising a semiconductor film including a channel forming region, and source and drain regions with said channel forming region extending therebetween, a gate insulating film covering the semiconductor film, and a gate electrode over said gate insulating film, wherein said gate insulating film has a first contact hole; an interlayer insulating film formed over said thin film transistor, wherein said interlayer insulating film has a second contact hole and is in contact with said gate electrode; an electrode formed over said interlayer insulating film and electrically connected to one of said source and drain regions through said first contact hole and said second contact hole, wherein said electrode is in contact with said one of said source and drain regions in said first contact hole; a leveling film comprising an organic resin formed over said electrode, wherein said leveling film has a third contact hole; and a pixel electrode formed over said leveling film and electrically connected to said electrode through said third contact hole, wherein said gate insulating film contains fluorine and is in contact with a top surface and side surfaces of the semiconductor film, wherein said third contact hole is located apart from said first contact hole and said second contact hole, and wherein said pixel electrode is transparent.
