Electro-optical device
First Claim
1. An electro-optical device, comprising, on a substrate:
- scanning lines and data lines that intersect with each other to form a grid-like pattern;
thin-film transistors, each of the thin-film transistors being connected to one of the scanning lines and one of the data lines;
pixel electrodes respectively connected to the thin-film transistors; and
a storage capacitor laminated above the each of the scanning lines, the storage capacator including a pixel-potential capacitive electrode connected to the pixel electrode and being at a pixel-electrode potential, a fixed-potential capacitive electrode being at a predetermined potential, and a dielectric layer disposed between the pixel-potential capacitive electrode and the fixed-potential capacitive electrode.

Abstract
The present invention provides electro-optical device that can include, on a TFT array substrate, pixel electrodes, TFTs for switching the respective pixel electrodes, and scanning lines and data lines respectively connected to the TFTs. By laminating a capacitive electrode and a capacitive line with an interlayer insulator interposed therebetween, a storage capacitor can be formed in a region overlapping the scanning line in a plan view. This arrangement increases a pixel aperture ratio and the capacitance of the storage capacitor, thereby reducing cross-talk and ghost and presenting a high-quality image display.
