Abstract
An electro-optical device includes a mirror being positioned above a surface of a substrate and modulating light, and a torsion hinge being positioned between the mirror and the substrate and pivotably supporting the mirror. The electro-optical device includes beam portions being disposed between the mirror and the substrate at positions that do not overlap the mirror in plan view, and being supported by the substrate while being spaced away from the mirror and the substrate. Spring tips that regulate a pivot range of the mirror protrude from the beam portions toward positions that overlap the mirror in plan view.
