ABSTRACT:
An electro-optical device includes: a substrate; data lines and scanning lines extending to cross each other on the substrate; thin film transistors that are disposed to correspond to intersections of the data lines and the scanning lines in plan view above the substrate and are disposed below the data lines; storage capacitors that are disposed above the data lines, each of the storage capacitors being formed by stacking a pixel-potential-side electrode, a dielectric film, and a fixed-potential-side electrode in this order from below; pixel electrodes that are disposed for respective pixels defined in correspondence with the data lines and the scanning lines in plan view above the substrate, each of the pixel electrodes being electrically connected to the pixel-potential-side electrode and each of the thin film transistors; and an interlayer insulating film stacked above the dielectric film. Each of the storage capacitors has a stacked structure in which the fixed-potential-side electrode is stacked on the dielectric film exposed through an opening passing through the interlayer insulating film.
