Patent ID: 8124974

Claim:
A display device where thin film transistors are formed on a substrate, characterized in that in said thin film transistors, a gate electrode is formed on a semiconductor layer with a gate insulating film in between, said thin film transistors include at least a first thin film transistor and a second thin film transistor, and said semiconductor layer is divided into individual regions for each film transistor, said semiconductor layer is provided with a common region shared either by the drain region of said first thin film transistor and the source region of said second thin film transistor or by the source region of said first thin film transistor and the drain region of said second thin film transistor, in the first thin film transistor and the second thin film transistor, the semiconductor layer is provided with LDD regions where the impurity concentration is lower than in said drain region and said source region, between the channel region and the drain region, as well as between the channel region and the source region, and said gate electrode comprises an integrated gate electrode formed as one body for said first thin film transistor and said second thin film transistor that faces at least said common region in said semiconductor layer, said channel region and said LDD regions of said first thin film transistor and said channel region and said LDD regions of said second thin film transistor.
