The LC material showing fast response characteristics at a low temperature is needed in the current LCDs. LCDs embedded with metal nanoparticles of Ag/Pd show a short response time by 3 to 5 times compared to those without nanoparticles. This phenomenon is shown to be attributed to the reduction of rotational viscosity be 70% at room temperature and be 30% at a low temperature (−20°C) and also to the alteration of elastic constants by doping nanoparticles.
