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.
Claims9
An electro-optical device, comprising, above 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 disposed in correspondence with intersections of one of the scanning lines and one of the data lines;
- pixel electrodes respectively being disposed in correspondence with the thin-film transistors;
- and
- a storage capacitor laminated between the thin-film transistor and the data line;
- and
- a first light shielding film laminated between the data line and the pixel electrode.
