Abstract:	一般而言背光模組所發出的光被視為非偏振光(unpolarized light)，然而經由我們的實驗結果與理論分析，背光模組所發出的光為本篇論文主要是經由實驗量測與理論分析來討論背光模組發光的部分偏振(partial polarization)狀態，並藉由適當的使用相位延遲板來加以利用此種部分偏振態以嘗試提升亮度。經由實驗顯示此法除了有提升亮度的效果外，也增加了亮度對視角的均勻性，這對日益重視良好顯示品質的顯示器而言提供了另一種應用參考。 It is generally considered that light come from backlight is unpolarized.However, as the result of our experiment result and analysis by theorem,light generating by backlight is partially polarized.In this article we discuss the polarization state and find the wave vibrating direction of major polarization light generated by backlight.Furthermore we design the suitable retardation plate to make the major polarization light for good use.According to our experiment we increasing the efficiency of utilizing light generated from backlight and get more uniform luminance with different viewing angle.(decrease the luminance variation with viewing angle changed). It could be referable for display application which is increasingly particular about display quality.
