雙穩態反射式聚合物穩定膽固醇液晶可以用高/低電壓脈衝反覆切換亮態/暗態，而且這兩種狀態都是穩態，不需要外加任何電壓便可以維持其狀態達數年之久，此外，其工作原理藉由反射外界的可見光來呈現亮態，不需要背板光源，因此可以有效節省電力，而且不需要偏振片更節省成本，在小尺寸省電型的顯示器方面極有潛力。
本論文便是研究這方面的主題，研究並量測其光電特性還有在UV 照射期間樣品的變化，並且用Berreman’s 4x4 matrix模擬其在planar結構下的反射特性，與量測結果比較，希望能以電腦模擬預知一個成品的優劣與否，以避免浪費無謂的人力，物力與時間，最後，第五章提出一些可以繼續發展的實驗觀念。

Applying a high/low voltage pulse, we can switch a bistable reflective polymer-stabilized cholesteric texture (PSCT) device between the reflective and transparent states. These two states are stable for years in the absence of voltage. In addition, this device is operated under the reflective mode without a polarizer. No backlight is required. As a result, it has potential for use as a display.
This thesis researches this PSCT device. Tasks include the fabrication of PSCT devices and the measurements of their reflection characteristics. In addition, using Berreman’s 4x4 matrix, we simulate the reflection characteristics of PSCT devices. It shows that the simulated results fit well with the measured ones. Thus this simulation provides us a good approach to predict the properties of PSCT devices, and save us not only money but also effort and time.
Finally in Chapter 5, I propose some ideas which deserve to carry out further with PSCT devices.
