In this study, we investigated the effect of ultraviolet (UV) polarization direction and UV curing temperature on the retardation dispersion during photopolymerization of a self‐assembly smectic reactive mesogen (RM) compound. The RM retarder film fabricated with unpolarized UV light showed a positive dispersion (PD) of retardation. Also the film that was photopolymerized with UV light linearly polarized orthogonal to the layer plane showed a non‐uniform negative dispersion (ND). On the other hand, the film photopolymerized with UV light linearly polarized parallel to the layer plane showed a ND of retardation with decreasing UV‐photopolymerization temperatures.
