Abstract
An electro-optical device includes: a substrate; a plurality of pixel units provided in a display region on the substrate; and a driving circuit that is provided in a peripheral region surrounding the display region and includes semiconductor elements that drive the plurality of pixel units, each of the semiconductor elements having a first semiconductor layer and a second semiconductor layer. The first semiconductor layer has an SOI (silicon on insulator) structure including a first single crystal silicon layer, and the second semiconductor layer is formed of a second single crystal silicon layer that is formed on the first semiconductor layer by epitaxial growth.
