本論文簡要介紹扭曲向列型(TN-LCD)顯示器、半穿透半反射式顯示器的基本概念以及液晶光學模擬軟體DIMOS的運算依據：22廣義瓊斯矩陣(Extended Jones Matrix Method)和44貝里曼矩陣(Berreman Matrix Method)。
藉助液晶光學模擬軟體DIMOS，我們詳細的模擬分析不同扭曲旋轉角φ、入射光偏振與液晶前導軸夾角β以及液晶盒厚度d，此三變數對反射式MTN(Mixed Mode Twisted Nematic)液晶盒的光學特性之影響。從中選擇最佳反射式條件，然後建議了四組半穿透半反射式顯示器的參數，模擬分析此四組參數的特點，並說明為何反射區的對比、視角不佳的原因，建議提供改良之方式。
最後藉由實驗與模擬結果相比較，印證模擬的可靠性。

Initially, we have briefly introduced the concepts of twisted nematic LCD (Liquid Crystal Display), transflective LCD, 2*2 extended Jones matrix method and 4*4 Berreman matrix method.
The simulation software DIMOS is then used to optimize the display parameters of a reflective Mixed-Mode Twisted Nematic Liquid Crystal cell. The parameters including the twisted angle, φ, the angle between polarization axis of the incident beam and the front LC director, β and LC thickness, d are investigated. Based on these optimization analyses, four operation modules are proposed for their application as a transflective LCD. The simulation results of these for modules are given. Briefly the contrast and viewing angle for the reflective regions need further improvement. The method how to improve it is suggested.
Finally, we check the simulation results which are found to agree with experimental results well.
