A polymer‐stabilized liquid‐crystal blue phase with a Kerr constant 170 times larger than that of nitrobenzene is shown to be capable of microsecond electro‐optical switching over a wide temperature range in flat Kerr cells, without need for additional surface processing to generate alignment. The Figure shows a polarizing optical micrograph, under crossed polarizers, of an in‐plane switched Kerr cell containing the polymer‐stabilized blue phase.
