Abstract

A novel methodology for designing wide view circular polarizers is proposed. Both single wavelength and broadband wide-view circular polarizers are discussed. Over the ±85° viewing cone, the light leakage from the crossed circular polarizers is less than 2.87�?10-4 using the proposed single wavelength circular polarizers (λ=550 nm) and less than 1.7�?10-3 using the proposed broadband circular polarizer (λ=450~650 nm). An example of using the designed broadband, wide-view circular polarizers for enhancing the optical efficiency of a direct-view liquid crystal display is elucidated.
