• Switching dynamics have been investigated in homogeneously aligned 5 μm thin cell filled with (FLC-6980) ferroelectric liquid crystal mixture using field reversal method and Sawyer Tower method. The effect of applied voltage and temperature on switching time has been studied. It has been observed that switching time decreases with the increase of applied voltage and also with the rise of temperature. The tortional viscosity has been calculated. It shows Arrhenius type behavior. Hysteresis loop has been studied at different temperatures and at different frequencies. It has been observed that coercive field ($E_{\text{c}}$) increases with the increase of frequency. $E_{\text{c}}$ has non-zero value at zero frequency, which is important characteristics of ferroelectrics. $E_{\text{c}}$ increases near the transition temperature.
