Herein, we report the effect of a 40% weakening of the surface polar anchoring energy of liquid crystal devices when the polyimide layers were doped with the nanoparticles of BaTiO 3 . This effect leads to the reduction of the threshold voltage by 6% and also the enhancement of the contrast ratio of twisted‐nematic liquid crystal displays (TN‐LCDs) at the saturation voltage by 130%.
