Liquid crystalline (LC) materials, particularly, polymers allow generating molecular orientation patterns with submicrometer resolution. By that, materials and fabrication technology have been developed to reach half-wave (HW) retardation for visible and even infrared wavelengths thus ensuring feasibility of geometrical phase optical components that are practically 100% efficient. Such LC polymer films allow rich architectures for designing spectrally selective optical components and polarization-independent systems. Thin LC films with customized optical functions make promising basis for high throughput and high definition display systems.
