Abstract
A liquid-crystal optical element comprises a plurality of wiring electrodes formed between a plurality of segment electrodes and a lower transparent substrate and connected electrically to the segment electrodes, individually, and a plurality of contact electrodes connected to the segment electrodes and the corresponding wiring electrodes. The adjacent segment electrodes are different in height position above the lower transparent substrate. A contact electrode that is connected to that one of each two adjacent segment electrodes which is situated on the side of a liquid crystal layer is connected to the destination segment electrode inside its edge, when viewed along a section formed by cutting the segment electrode in the direction perpendicular to the planes of the lower and an upper transparent substrate.
