    Abstract: A liquid crystal (LC) lens comprises a first substrate, a first electrode structure, an electrically tunable LC layer structure, a second substrate and a second electrode structure, wherein the electrically tunable LC layer structure is arranged between the first substrate and the second substrate. The electrically tunable LC layer structure includes at least two LC layers stacked on top of one another, and each LC layer further includes at least one LC unit. In the stacked structure, at least one of the LC layers includes at least one partition unit to partition the LC layer into one or more LC units. The layout of the LC units of the upper LC layer differs from that of the lower LC layer. In the present invention, the shape and layout of the LC units are designed to provide better optical performance without changing the thickness of the liquid crystal lens.
