Abstract Frequency effects on polymer‐stabilized blue‐phase liquid crystals (BPLCs) are investigated. As the electric field frequency increases, Kerr constant decreases and dielectric heating increases. A physical model (extended Cole‐Cole model) is proposed to fit the experimental results. These results are important on high frequency operation of BPLC displays.
