Development of liquid crystal devices is an important topic due to display technology. Modification of electro-optical properties of liquid crystals can be possible by doping nanoparticles. Adding low concentration ferroelectric nanoparticles to a nematic liquid crystal enhances the behavior of electro-optical response and lowers the operating voltage due to interaction between the nanoparticles and liquid crystal molecules [1]. Thus, it is also possible to modify capacitance-voltage characteristics of a liquid crystal by doping nanoparticles [2]. 
In this study, the experimental measurements on the capacitance-voltage characteristics of a pure liquid crystal and nanoparticle doped liquid crystal films were carried out by an impedance analyzer. Frequency-dependent capacitance measurements were also studied.
