An antireflective film plays a crucial role in a variety of optical technologies for flexible display devices. To develop a single-layered coatable compensation film, we programmed a X–shaped negative dispersion reactive mesogen (XNM) which contains the conjugated backbone with two imine bonds and two alkyl chains. The single-layered compensation films were fabricated by coating, self-assembly with subsequent photopolymerization of the smectic host RM and XNM mixture. Through the optical measurements, it was found that the optimized content of XNM was 40 wt%. The optimized single-layered coatable compensator shows the ideal molecular self-assembly and negative dispersion retardation, resulted from host-guest molecular arrangement. This work help to understand importance of phase and self-assembly behaviors of the host-guest system in fabricating single-layered compensator.
