纳米相分离液晶(Nano-Phase-Separated Liquid Crystals，NPS LCs)技术，是指一液晶组合物层包含多个液晶分子及多个可聚合单体，在输入电压时通过紫外光照射所述多个可聚合单体，以形成多个聚合物网络。这些聚合物网络可以促使所述多个液晶分子的响应速度达到1毫秒内。
然而，纳米相分离液晶技术具有光线穿透率较低的缺点，这是因为纳米相分离液晶技术通常采用完全透明导电膜(Full ITO)的技术，亦即在上基板及下基板上皆形成一个完整的透明导电膜。这种透明导电膜无法利用现有技术的方式(例如制作多个凸起物(Bump)或蚀刻多个沟槽(slit)等)来使所述多个液晶分子产生一预倾角。所以，在进行输入电压时通过紫外光照射所述多个可聚合单体的步骤时，若是相邻的液晶分子的倾倒方向不一致时，光线穿透率会降低。
