Patent ID: 7541618

Claim:
A liquid crystal display device comprising: a thin film transistor formed over a substrate, the thin film transistor including at least a channel forming region, a source region, a drain region, a gate insulating film and a gate electrode; a scanning line formed over the substrate wherein the scanning line is connected to the gate electrode of the thin film transistor; a signal line formed over the substrate and electrically connected to one of the source region and the drain region of the thin film transistor wherein the signal line extends across the scanning line; a storage capacitor electrically connected to the other one of the source region and the drain region of the thin film transistor, the storage capacitor including a capacitor wiring formed on a same surface as the gate electrode; an insulating film formed over the thin film transistor, the scanning line, the capacitor wiring and the signal line; and a pixel electrode formed over the insulating film and electrically connected to the other one of the source region and the drain region of the thin film transistor, wherein at least a portion of the capacitor wiring extends in a direction parallel with the signal line, wherein the gate electrode is formed in a different layer from the scanning line.
