Abstract

An optical axis deflecting element is provided with a pair of transparent substrates, a liquid crystal layer disposed between substrate surfaces of the pair of transparent substrates and having a chiral smectic C-phase forming a homeotropic orientation, and a plurality of electrode pairs each defining one of a plurality of divided regions into which an effective region of the liquid crystal layer is divided, wherein an electric field is independently applicable to each divided region defined by a corresponding electrode pair in a direction parallel to the substrate surfaces.
