Patent ID: 7348943

Claim:
A camera having a display device comprising: a first line; a second line; a third line; a fourth line; a first thin film transistor; a second thin film transistor; a first capacitor; and a second capacitor, wherein the first line, the second line, the third line, the fourth line, the first thin film transistor, the second thin film transistor and the first capacitor are formed over an insulating substrate; wherein one of a source region and a drain region of the first thin film transistor is electrically connected to the first line, the other of the source region and the drain region of the first thin film transistor is electrically connected to one end of the first capacitor, and the other end of the first capacitor is electrically connected to the third line; wherein one end of the second capacitor is electrically connected to one of a source region and a drain region of the second thin film transistor, the other end of the second capacitor is electrically connected to the second line, and the other of the source region and the drain region of the second thin film transistor is electrically connected to the third line; and wherein the fourth line is electrically connected to a gate electrode of the first thin film transistor.
