Popis: We have measured intrinsic light leakage of VA and IPS LC cells between “ideal” crossed polarizers as a function of temperature. The measured intrinsic light leakage of VA LC cell were independent of temperature up to the nematic-to-isotropic transition temperature in comparison to a increasing light leakage as temperature increases in IPS LC cells arranged in either o-mode or e-mode configuration. We have derived equations based on light scattering caused by fluctuations[1] of nematic LC director to explain our experimental results.
