Description
LCDディスプレイに使用されるフィルム積層体に関する、波長の関数としての透過率を決定するために、シミュレーションを行った。シミュレーションは、Sanayi System Co.Ltd.(Incheon,Korea)から市販されているシミュレーションソフトウェアである、TechWiz LCD 1D Plusを使用して行った。TechWizデータベースによって提供されるランベルト光源オプションを、全てのシミュレーションに使用した。
LC移相子の厚さが1.22ミクロンで固定され、COP移相子の遅軸と反射偏光子のパス軸との間の角度(以降、COP角)が45度から60度まで様々であったことを除いて、実施例1と同様にシミュレーションを行った。LC移相子の遅軸と反射偏光子との間の角度(以降、LC角)は、COP移相子の遅軸とLC移相子の遅軸との間の相対角度を90度(すなわち、LC角は、COP角−90度)で維持しながら、−45度から−30度まで様々であった。
LC移相子の厚さが1.22ミクロンで固定され、COP移相子の遅軸と反射偏光子のパス軸との間の角度が45度から35度まで様々であり、一方でLC移相子の遅軸と反射偏光子のパス軸との間の角度が−45度から−35度まで様々であったことを除いて、実施例1と同様にシミュレーションを行った。COP移相子の遅軸とLC移相子の遅軸との間の相対角度は、90度から70度まで様々であった。
