Abstract

An electro-optical device includes a first light shielding film; a transistor element formed on the first light shielding film to overlap the first light shielding film; a second light shielding film formed on the transistor element to overlap the transistor element and electrically connected to an input terminal of the transistor element; a transparent conductive film extended toward an upper layer side of the second light shielding film in an opening region, through which light penetrates, of the display region; a dielectric film formed on the transparent conductive film in the opening region; and a transparent pixel electrode formed on the dielectric film in the opening region, constituting a storage capacitor together with the transparent conductive film and the dielectric film, and having a transparent pixel electrode which is electrically connected to the transistor element.
