The novel helix‐free ferroelectric liquid crystals developed at the Lebedev Physical Institute are characterized with the spatial deformation of smectic layers and soliton mechanism of director reorientation and show fastest electro‐optical response at lowest control voltage. The conditions are studied to increase the frequency interval of hysteresis‐free modulation (was extended to 6 kHz) and the temperature interval, in which the response time is practically constant (it is from 12 to 52 °C now). These FLC materials are very promise for future Field Sequential Color and 3D displays.
