Popis:	In this paper, we propose a method of suppressing the increase in operating voltage caused by the in-cell retarder in transflective liquid crystal displays (LCDs), by doping nanoparticles with a high dielectric constant in the in-cell material. Doping with nano-particles increases the dielectric constant of the in-cell material by more than 5 times that of a pure in-cell material. The in-cell material with a high dielectric constant reduces the magnitude of the electric field, within the volume of the in-cell retarder, to decrease the operating voltages of a transflective LCD with an in-cell retarder. It is confirmed that the increase in operating voltage, in a transflective vertical alignment (VA) cell with an in-cell retarder, can be suppressed, from 3.8 to 0.7 V, by doping an in-cell material with 5 wt % TiO2.
