为后代实现更高质量的液晶显示器的关键挑战是开发具有更快电光响应的新液晶材料和简化设备的制造工艺。蓝相1 -4是液晶相的一种，与常用的蓝相相比具有两个主要优点。第一，反应快得多5 -8。第二，零电场状态是光学各向同性的，不像非晶相，也就是说，不需要表面处理（没有摩擦），从而简化了制造过程。蓝相的问题之一，即可用的温度范围非常窄，已经被我们最近的成就所克服，聚合物稳定的蓝相9，10。在这里，我们表明，聚合物稳定的蓝相克服了另一个问题，蓝相是非常脆弱的电场。我们还证明了足够大的电场诱导的双折射和微秒响应的聚合物稳定的蓝相没有任何表面处理。
Key challenges in achieving higher-quality liquid crystal displays for future generations are developing new liquid crystal materials with faster electro-optical response and simplifying the fabrication process of devices. Blue phases1-4, kinds of liquid crystal phases, have two major advantages over commonly used nematic phases. First, the response is much faster5-8. Second, the zero-electric field state is optically isotropic unlike nematic phases, that is, no surface treatment (no rubbing) is necessary, leading to a simplification of the fabrication process. One of the problems of blue phases that the available temperature range is very narrow has been overcome by our recent achievement, the polymer-stabilized blue phases9,10. Here we show that the polymer-stabilized blue phases surmount another problem that the blue phase is very fragile to an electric field. We also demonstrate the sufficiently large electric field-induced birefringence and the micro-second response of the polymer-stabilized blue phases without any surface treatment.
