Abstract

An electro-optical device includes a pixel electrode provided over one side of a substrate, a conductive layer provided between the substrate and the pixel electrode, and a relay electrode provided between the substrate and the conductive layer. The conductive layer includes a conduction section protruding toward the relay electrode. The conduction section is a cylindrical-shape having a bottom surface which is attached to the relay electrode. The conduction section is filled with an insulating material. The pixel electrode is electrically connected to the relay electrode through the conductive layer.
