Patent ID: 7053410

Claim:
An electro-optical device, comprising: a first substrate; a second substrate; an electro-optical material in between the first and second substrates; data lines extending in a first direction; scanning lines extending in a second direction in such a manner that the scanning lines and data lines cross each other; pixel electrodes and thin-film transistors each placed in regions corresponding to intersections of the scanning lines and data lines, the thin-film transistor disposed in between the first substrate and the data lines; storage capacitors each disposed in between the first substrate and the data lines and each electrically connected to corresponding ones of the thin-film transistors and pixel electrodes; a capacitor line disposed in between the electro-optical material and the data lines; first junction electrodes formed using the same film as that for forming the data lines, each first junction electrode electrically connecting a corresponding constant potential capacitor electrode and the capacitor line; and second junction electrodes formed using the same film as that for forming the data lines, each second junction electrode electrically connecting a corresponding pixel potential capacitor electrode of a storage capacitor and pixel electrodes, wherein the data lines, first junction electrodes, and second junction electrodes each include a nitride film.
