Abstract： Liquid crystal display is now the dominant technology for information displays，which is widely used in smal size displays，such as calculators，mobile phones，and digital cameras；medium size displays， such as laptops and desktop monitors； large size displays，such as direct-view TV and projection TV. Although traditional liquid crystals，such as nematic liquid crystals and cholesteric liquid crystals，exhibit fast response to electric field， higher quality displays are pursued along with the improvement of the people's living standards. It requires liquid crystals of faster response to satisfythe dynamic display of high resolution. This paper systematically summarizes the factors afecting the LC response，and emphasizes several kinds of new liquid crystals of fast responsiveness，such as polymer stabilized blue phase liquid crystal， ferroelectric liquid crystal，ferroelectric nematic liquid crystal and electric modulation of order parameters.

Finally，we rationally anticipate the promising applications of fast response liquid crystals in displays and photonic devices.

Key words： fast response； blue phase liquid crystal；ferroelectric liquid crystal； ferroelectric nematic liquidcrystal;order parameter

1引言

在发明液晶显示器（liquid crystal display，LCD）之前，阴极射线管（cathoderay tube，CRT）显示器是最主要的显示器类型，其具有可视角度大、响应时间短、对比度高等优点，但由于其体积大、重量大、存在辐射等负面原因，逐渐被液晶显示器所取代。（剩余24239字）
