Abstract
An electro-optical device includes a substrate having light-transmissivity, a capacitance element having light-transmissivity and including a first electrode, a dielectric layer, and a second electrode, a first insulating film having light-transmissivity, a light-shielding film, a second insulating film having light-transmissivity, and a transistor. The first electrode, the dielectric layer, the second electrode, the first insulating film, the light-shielding film, the second insulating film, and the transistor are layered in this order from the substrate side, and an interfacial reflection at the first insulating film side of the light-shielding film is greater than an interfacial reflection at the dielectric layer side of the first electrode with respect to light entering from the substrate.
