Frequency dependence of the complex dielectric constant for liquid crystal materials doped with a TBAI (tetrabutyl-ammonium-iodide) are investigated in a low frequency region. The experimental results are analyzed by utilizing a novel equivalent circuit where contributions from space charge polarization and the electric double layer are taken into consideration. Additionally, the contributions from plural kinds of ions with different values of diffusion coefficients to the complex dielectric constant are discussed in terms of the space charge polarization. By the theoretical analysis, the frequency dependent dielectric properties, which is characteristic to the behaviors of the ions, can be well explained and information on the attributes of ions such as diffusion coefficient and density are obtained.
