Patent ID: 7847871

Claim:
An electro-optical device comprising: a plurality of data lines and a plurality of scanning lines that intersect each other; a plurality of pixel electrodes each in pixels at positions corresponding to intersections between the data lines and the scanning lines; a plurality of transistors each being formed in a corresponding pixel, each of the transistors including a semiconductor film and a gate electrode, the semiconductor film of each transistor having a channel region, a data-line-side source/drain region that is electrically connected to the data line, a pixel-electrode-side source/drain region that is electrically connected to the pixel electrode, a first junction region that is formed between the channel region and the data-line-side source/drain region, and a second junction region that is formed between the channel region and the pixel-electrode-side source/drain region, the gate electrode of the transistor overlapping the channel region; a plurality of first storage capacitors each in a corresponding pixel, each first storage capacitor having: a first capacitor electrode that is made of the same film as one of the semiconductor films and a second capacitor electrode provided at a layer over the gate electrode and opposite to the first capacitor electrode with a first dielectric film being formed between the first capacitor electrode and the second capacitor electrode, the second capacitor electrode has a first main portion that is formed opposite to the first capacitor electrode and an extending portion that extends from the first main portion to at least partially cover the second junction region; and an interlayer insulation film that insulates the extending portion from the transistor.
