A new TN‐LCD exhibiting a frequency modulation, called FM‐TN‐ LCD, has been fabricated by doping Pd nanoparticles that are covered with nematic liquid crystal molecules, whose dielectric anisotropy is negative (Δ∍ > 0) and its sign is opposite to that of the host NLC (Δ∍ > 0). Luminance level and the threshold voltage of this LCD are controlled by changing the frequency of the applied pixel voltage from 20Hz to 100Hz by keeping the operation voltage just above the threshold voltage.
