Electrically tunable optical phase modulation element
An electrically tunable optical phase modulation element is provided comprising a first substrate, a second substrate, a liquid crystal layer, a plurality of first stripe electrodes, a first anti-mosaic layer, a first insulating layer, a plurality of second stripe electrodes, a second anti-mosaic layer, a second insulating layer and a controlling circuit. The first stripe electrodes and the first anti-mosaic layer are disposed in between the first substrate and the liquid crystal layer. The second stripe electrodes and the second anti-mosaic layer are disposed in between the second substrate and the liquid crystal layer, wherein an extension direction of the first stripe electrodes intersects with an extension direction of the second stripe electrodes. The electrically tunable optical phase modulation element of the disclosure can be used to eliminate a grid like electrical field generated in conventional electrically tunable lens to provide smoother electrical field distribution and better lens image quality.
