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.
