A cholesteric liquid crystal display device includes: a cholesteric liquid crystal display element; a segment driver and a common driver; a multi-voltage generation circuit configured to generate voltages supplied to the segment driver and the common driver; a temperature sensor; and a control circuit configured to control the segment driver, the common driver, and the multi-voltage generation circuit, wherein the control circuit: controls the segment driver and the common driver to perform a dynamic drive sequence having a preparation period during which the cholesteric liquid crystal is brought into a homeotropic state, a selection period during which the final state of the cholesteric liquid crystal is selected, and an evolution period during which the cholesteric liquid crystal is made to transition to the state selected during the selection period; and controls the applied voltage to the cholesteric liquid crystal during the evolution period to change in accordance with temperature.
