Liquid crystal optical lens and manufacturing method thereof, lens apparatus using liquid crystal optical lens

A liquid crystal optical lens, comprising:

• a first device substrate comprising a first electrode layer and a plurality of first stacked layers stacked in sequence thereon, wherein each of the first stacked layers has a first opening exposing the first electrode layer, and each of the first stacked layers comprises a first conductive layer and a first insulating layer disposed between the first conductive layer and the first electrode layer;
• a second device substrate comprising a second electrode layer and a plurality of second stacked layers stacked in sequence thereon, and the second device substrate is configured opposed to the first device substrate, wherein each of the second stacked layers has a second opening exposing the second electrode layer, and each of the second stacked layers comprises a second conductive layer and a second insulating layer disposed between the second conductive layer and the second electrode layer;
• and
• a liquid crystal layer disposed between the first device substrate and the second device substrate and configured in the first opening and the second opening, wherein the liquid crystal layer completely fills the first opening and the second opening between the first electrode layer and the second electrode layer, wherein the first device substrate and the second device substrate are opposite and symmetrical to each other.
