Abstract:
An electro-optical device comprising, on a support substrate;a plurality of scanning lines; a plurality of data lines which intersects the plurality of scanning lines; a transistor connected to each of the scanning lines and each of the data lines; a pixel electrode connected to each transistor; an insulator layer formed beneath a semiconductor layer of the transistor serving as a channel of the transistor; and an electrically conductive light-shielding layer formed between the insulator layer and the support substrate, an extension portion of the semiconductor layer serving as a channel of the transistor being electrically connected to the light-shielding layer, wherein the extension portion is connected to the light-shielding layer through an interconnect line that runs through a first contact hole formed in the extension portion and a second contact hole formed in the light-shielding layer.
