A series of ferroelectric glassy liquid crystals (FGLCs) were synthesized and evaluated for their potentials of fast switching ability less than 1 ms. The latest developed FGLC possesses wide chiral smectic C mesophase over 100 °C. The diluted FGLCs mixtures were also investigated using W206A as host. In particular, the 2% FGLC‐1 mixture obtains better alignment with good contrast than R2301 (Clariant, Japan) in the same pre‐made 2μm cell (from EHC). In the series of FGLC‐3 mixtures, the chiral smectic A phase was completely suppressed within all concentrations. These results provide new promising LC materials for fast switching, color sequential display.
