Ferroelectric columnar liquid crystals are materials in which the polar direction can be controlled by applying a voltage and can be maintained after removal of the voltage. In this study, we present an example of a perfectly bistable ferroelectric columnar liquid crystalline phase using a chiral urea compound. Electrical measurements show that this compound has a relatively faster response speed in the liquid crystal phase (0.19 sec) and hold the polar structure for over 10 hours. Furthermore, a helical
