Abstract:
1. An electro-optical device, comprising: a substrate; pixel electrodes formed above the substrate; thin film transistors to switch and control the pixel electrodes, the thin film transistors being constituted by a semiconductor layer; data lines to supply image signals to the thin film transistors; scanning lines to supply scanning signals to the thin film transistors, the scanning lines intersecting the data lines; an upper light shielding film to cover at least one of an upper side of channel regions and regions adjacent to the channel regions of the semiconductor layer constituting the thin film transistors; and a lower light shielding film to cover at least one of a lower side of the channel regions and the adjacent regions, in each of the upper light shielding film and the lower light shielding film having projecting portions projected to define corner cuts in an opening region of each pixel corresponding to the pixel electrodes in the intersection regions where the data lines and the scanning lines intersect each other, the channel regions being disposed in the intersection regions, and the upper light shielding film and the lower light shielding film being connected to each other via at least one of through a light shielding conductive material and directly in the projecting portions.
