ABSTRACT:
There is provided an electro-optical device comprising, above a substrate, a first conductor layer, a second conductor layer, an interlayer insulating film formed between the first conductor layer and the second conductor layer, and a contact hole, provided in the interlayer insulating film, for electrically connecting the first conductor layer and the second conductor layer in a contact portion. The first conductor layer has a multilayered structure in which an electrolytic corrosion preventing film is provided on a conductor film, in a region including at least the contact portion among the entire region thereof, and the electrolytic corrosion preventing film is not provided in other regions thereof. Thus, an electrolytic corrosion can be prevented and a contact resistance can be reduced. Further, heat can be prevented from generating.
