Liquid crystal light beam broadening devices and their manufacture are described. Beneficial aspects of beam broadening devices employed for controlled illumination and architectural purposes are presented including providing symmetric beam broadening, improving the beam intensity profile, beam divergence preconditioning and improving projected beam intensity uniformity. Both beam control devices having in-plane and homeotropic ground state liquid crystal alignment are presented.
