Low‐temperature effect on the liquid crystal response time for mobile displays is investigated. Rotational viscosity, elastic constants and response time of two commercial LC mixtures are studied in the range of −20 °C to 60 °C. At low temperatures, rotational viscosity still follows the exponential law well but elastic constants are ∼30–40% larger than those expected from mean field theory. The responsible physical mechanisms are explained.
