1. A method of controlling the electro-optical properties of a polymer dispersed liquid crystal (LC) film, comprising:

  • forming a solution of a LC dissolved in a polymerizable monomer system,photopolymerizing said solution to form a polymerized film having a dispersion of LC bubbles therein, andspatially varying the conditions of polymerization over said film to spatially vary the sizes of said LC bubbles therein.
