We prepared cyclodextrin (CyD)‐capped silica (CyD‐SiO 2 ) nanoparticles and poly(cyclodextrin) (PCyD)‐capped silica (PCyD‐SiO 2 ) nanoparticles. The average diameter of SiO 2 nanoparticles capped by αCyD, βCyD, γCyD and PγCyD are 9.4, 8.4, 10.6, and 6.4 nm, respectively. The nanoparticles were dispersed in liquid crystal; 4′‐pentyl‐4‐cyanobiphenyl to construct novel twisted nematic liquid crystal device (TN‐LCD). The response time of this TN‐LCD in the presence of PγCyD‐SiO 2 nanoparticles was faster than that in the absence.
