Abstract
Influence of photopolymerization condition of UV-curable liquid crystals on the transparency of optical anisotropic plastic films was investigated. Nematic phase was observed at room temperature in novel compositions investigated in this study. Transparency of the optical anisotropic films was improved by adding the swallow-tailed compounds to UCL-001. Diffusion transmittance reduced as increasing either intensity or total energy of UV irradiation. Retardation of these films decreased as increasing not only intensity but also total energy of irradiated UV light. It was suggested that haze was caused by light scattering from small regions of differing refractive index. Retardation and total transmittance showed opposite behavior against the conditions of UV irradiation.
