Electro-optical device, method of manufacturing electro-optical device, and electronic apparatus
An electro-optical device is configured by a laminated body of a second conductive layer and a reflective layer for a mirror. The second conductive layer includes a mirror support post facing a concave portion at a side opposite to a substrate, and a flat plate which extends from an end portion of the mirror support post and faces the substrate. The concave portion is filled with the resin. Surfaces of the flat plate and the resin configure a continuous plane. The reflective layer for a mirror is laminated on a surface of the resin at a side opposite to the substrate, and a surface of the flat plate of the second conductive layer at a side opposite to the substrate.
