The transient capacitance and transient charging current simultaneous measuring system of liquid crystal (LC) cell is presented. The waveform of the current-voltage dependence of the LC cells is measured by applying a triangle wave of voltage with a step bias. We discuss transient characteristics of orientation of liquid crystal molecules and impurity ions in liquid crystal cell from the transient capacitance, transient resistance and the transient charging current. This transient simultaneous measuring system is useful for investigating the relationship between the polarizations due to impurity ions and the orientation of liquid crystal molecules.
