Retardation‐adjustable photo‐induced biaxial cholesteric films using reactive mesogen mixtures (RMMs) for a viewing angle compensation of vertically aligned liquid crystal displays (VA‐LCDs) are being developed. Retardation can be easily controlled by changing the RMM compositions, thickness of cholesteric layers and conditions of exposed polarized UV light such as peak irradiance, energy density and the extinction ratio. The photo induced biaxial cholesteric films can compensate for a wide range of the cell‐gap of VA‐LCDs with excellent viewing angle properties.
