Abstract
An electro-optical device including a substrate, data lines and scanning lines, thin film transistors being disposed below the data lines and above the substrate. Storage capacitors are disposed over the data lines in a region opposite to the channel region of the thin film transistors in plan view. Each storage capacitor has a pixel-potential-side electrode, a dielectric film, and a fixed-potential-side electrode that have been formed sequentially. The pixel electrodes are disposed over the storage capacitors so as to correspond to the data lines and the scanning lines on the substrate in plan view, and the pixel electrodes are electrically connected to the pixel-potential-side electrodes and the thin film transistors. This abstract is intended only to aid those searching patents, and is not intended to be used to interpret or limit the scope or meaning of the claims in any manner.
