Abstract

An electro-optical device according to the present invention includes, above a substrate, pixel electrodes, thin film transistors connected to the pixel electrodes, an upper light shielding film to cover the upper side of the channel regions of the thin film transistors, and a lower light shielding film to cover the lower side of the channel regions of the thin film transistors. Each of the upper light shielding film and the lower light shielding film has projecting portions to define corner cuts in an opening region of each pixel, in the intersection regions where data lines and scanning lines intersect each other. Both projecting portions are connected to each other through contact holes. The channel region of the thin film transistors are disposed in the intersection regions.
