碩士 === 國立中央大學 === 光電科學研究所碩士在職專班 === 93 === 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.
