6-9 低電圧駆動TN-LCDの光学設計(第6部門 情報ディスプレイ)

抄録

We analyzed the polarization shift inside twisted nematic liquid crystal display (TN-LCD) and clarified the S-shaped polarization shift on Poincare sphere in black state was important to realize low-voltage driving TN-LCD. We realized high contrast ratio of 150000:1 with low driving voltage of 2.5V by optimization of optical compensation films.
