A polymer-stabilized blue-phase liquid crystal (BPLC) with microsecond response time is demonstrated using a vertical field switching cell. The measured decay time is 39.4 μs at room temperature (21°C) and then decreases to 9.6 fis at 44.3 °C. Such a response time is 1-2 orders of magnitude faster than that of a typical BPLC device. The responsible, physical mechanisms are the collective effects of short pitch length, strong polymer network, and low viscosity through elevated temperature effect. The on-state voltage of our BPLC device is 44.2 V, hysteresis is below 0. 7%, and contrast ratio is over 1300:1.
