An antireflective film is fabricated to have more advantages for optical properties than pre-existing film in the flexible display industry. To fabricate a single-layered coatable compensator film, we newly designed and synthesized a X–shaped guest reactive mesogen (XGRM) containing a conjugated aromatic core with two imine bonds and two alkyl chains. The single-layered compensation film was fabricated by coating, self-assembly with subsequent photopolymerization of XGRM and the smectic host rod-shaped RM mixture. Through the optical analysis, it was found that the optimized content of XGRM was 40 wt%. The optimized single-layered coatable compensator film shows the ideal negative dispersion retardation property owing to the host-guest molecular arrangement. This work helps to understand importance of self-assembly behaviors of the host-guest system in fabricating single-layered compensator.
