Abstract
Provided is a polarization-dependent lens structure. The lens structure includes an optically-isotropic polymer layer having a reverse lens shape on a first surface and a lens portion where the surface of the optically-isotropic polymer layer is filled with liquid crystalline polymers, nano-scale 1D lattice structures (nano-scale grooves) are formed on an upper surface thereof, and the liquid crystalline polymers are aligned by the nano-scale 1D lattice structures along a direction of long axes of the 1D lattice structures, wherein it is determined according to a polarization direction of incident light whether or not the polarization-dependent lens structure operates as a lens.
