Claim Text:
1. A liquid crystal (LC) lens, comprising: a first planar substrate having on a surface thereof a layer of first alignment material comprising a co-polymer of a first photosensitive monomer and at least one alkyl methacrylate monomer; and a second planar substrate having on a surface thereof a layer of second alignment material comprising a co-polymer of a second photosensitive monomer and at least one alkyl methacrylate monomer, wherein the first and second substrates are assembled in parallel configuration such that the layers of alignment material face each other and are spaced apart, and wherein the first and second photosensitive monomers are of different photosensitivities, and wherein particles of the first alignment material have a pretilt angle gradient that is different from a pretilt angle gradient of the second alignment material.
