Patent ID: 7443478

Claim:
An active matrix display device comprising: a first substrate having a pixel portion and a common contact portion; a second substrate having a counter electrode; said pixel portion comprising: a thin film transistor; a first insulating film provided over said thin film transistor; a second insulating film provided on said first insulating film; a pixel electrode provided over said second insulating film, the pixel electrode being electrically connected to the thin film transistor; and a liquid crystal between the pixel electrode and the counter electrode; said common contact portion comprising: a first conductive film provided over said first insulating film; said second insulating film provided on said first conductive film, said second insulating film having at least two openings; and a second conductive film provided on said second insulating film and in said openings; a plurality of conductive spheres held between said first substrate and said second substrate; wherein said first conductive film is connected with said second conductive film in said openings, wherein at least one of said conductive spheres is held over said second insulating film and in contact with both said second conductive film and said counter electrode.
