Patent ID: 7133086

Claim:
An image display having a plurality of thin film transistors and a plurality of capacitors on a substrate, wherein a plurality of gate-lines and a plurality of signal-lines which cross said plurality of gate-lines in a matrix shape are formed on said substrate, each of said thin film transistors has: an island-shaped semiconductor layer having a source region, a drain region, and a channel region sandwiched between them; a first insulation film formed between said island-shaped semiconductor layer and a gate electrode of the same layer as that of said gate-lines; an interlayer insulation film formed above said island-shaped semiconductor layer; and a source electrode and a drain electrode which are come into contact with said source region and said drain region via an opening formed in said interlayer insulation film and which exist in the same layer as that of the signal-lines, and each of said capacitors has: a storage electrode of the same layer as that of said gate-lines; a second insulation film formed in contact with said storage electrode, an upper surface of said interlayer insulation film, and a side surface of the opening formed in said interlayer insulation film; and an electrode which is formed on said second insulation film so as to be in contact therewith and which exists in the same layer as that of said signal-lines.
