Abstract:
1. A method for fabricating a liquid crystal device having polymer micro-structures, the method comprising the steps of: preparing a mixture comprising a liquid crystal material and a prepolymer; providing a first and second cell wall structure, said first and second cell wall structures optionally having electrodes disposed on facing sides of said first and second cell wall structures, and, optionally having an alignment layer disposed on at least one of said electrodes; disposing said mixture into a space between the first and second cell wall structures; causing said liquid crystal material to assume a predetermined orientation with a non-uniform spatially distorted director field; and exposing said mixture to conditions which cause polymerization of the prepolymer and formation of polymer micro-structures between the cell walls, wherein the micro-structures have a shape and spatial location determined by a director field of said liquid crystal material.
