Patent ID: 7952094

Claim:
An electro-optical device comprising: a substrate; scanning lines extending in a scanning-line direction; data lines extending in a data-line direction that intersects the scanning-line direction, the data lines including a first conductive light-shielding film; thin film transistors disposed below the data lines and above the substrate, at least one of the thin film transistors having a channel region, a source region, and a drain region; storage capacitors which are disposed over the data lines in at least a region opposite to the channel region of the thin film transistor in plan view, each storage capacitor having a pixel-potential-side electrode, a dielectric film, and a fixed-potential-side electrode that have been formed sequentially; pixel electrodes that are disposed over the storage capacitors so as to correspond to the data lines and the scanning lines in plan view, the pixel electrodes being electrically connected to the pixel-potential-side electrodes and the thin film transistors; and a second conductive light-shielding film that is formed by the fixed-potential-side electrodes and the pixel-potential-side electrodes, each of the fixed-potential-side electrodes being extended in the data-line direction and having an extending portion that extends to an endmost edge in the scanning-line direction, each of the pixel-potential-side electrodes being extended in the data-line direction and in the scanning-line direction and having a protruding portion that protrudes beyond the endmost edge of the fixed-potential-side electrode in the scanning-line direction, the protruding portion being in direct electrical and physical contact with the pixel electrode.
