Description
横方向電界モードであるIPSモード(In-Plane-Switchingモード)や、FFSモード(Fringe-Field-Switchingモード)がある。IPSモードやFFSモードの横方向電界モードの液晶表示装置は、同一基板上に形成された画素電極及び共通電極を有し、液晶層に横方向の電界を印加する。このため、横方向電界モードの液晶表示装置は、液晶分子を基板平行方向に回転させて画像の表示を行うことにより、TNモードの液晶表示装置に比して高視野角が実現できる。
<反射領域・電圧無印加>
反射領域、電圧無印加状態の場合の説明をする。
反射領域55では、液晶層53には第1偏光板51を通過した90°方向(縦方向)の直
線偏光が入射する。液晶層53では液晶層に入射した直線偏光の光学軸と、液晶分子の長
軸方向が一致しているため、90°の直線偏光のまま液晶層53を通過し、反射板54で
反射する。直線偏光の場合、反射しても直線偏光のままなので、90°直線偏光のまま、
再度、液晶層53に入射する。更に90°直線偏光のまま液晶層53を出射して第1偏光
板51に入射するが、第1偏光板の偏光軸も90°のため、第1偏光板51を通過する。
よって、電圧を印加しない場合、白表示となる。
反射領域、電圧印加状態の場合の説明をする。
反射領域55では、液晶層53には、第1偏光板51を通過した90°方向(縦方向)の直線偏光が入射する。液晶層53は電圧を印加することにより、液晶層53における液晶層の長軸方向を基板面内で0°から45°に変化する。液晶層53では、入射光の偏光方向と液晶分子の長軸方向とが45°ずれており、液晶のリタデーションがλ/4に設定されているため、液晶層53に入射した縦方向の直線偏光は、右回りの円偏光状態となって反射板54に入射する。この右周りの円偏光は、反射板54で反射し、左周りの円偏光状態となる。液晶層53に入射した左周りの円偏光は、液晶層53を再び通過し、横方向(0°方向)の直線偏光となって、第1偏光板51に入射する。第1偏光板51の偏光軸は90°のため、反射板54が反射した光を通過させることができず、黒表示となる。
以上のように、反射領域では電圧無印加で白表示、電圧印加状態で黒表示となるノーマ
リーホワイト表示となる。
次に透過領域について説明をする。まず、電圧無印加状態の説明をする。
透過領域56では、液晶層53には、第2偏光板52を通過した横方向の直線偏光が入射する。液晶層53では、入射光の偏光方向と分子方向長軸方向が直交しているため、偏光状態を変化させることなく、横方向の直線偏光のまま液晶層を通過し、第1偏光板51に入射する。第1偏光板の偏光軸は90°のため、透過光は第1偏光板を通過することができず、黒表示となる。
次に電圧印加状態を説明する。透過領域56では、液晶層53には、第2偏光板52を通過した横方向の直線偏光が入射する。液晶層53は電圧を印加することにより、液晶層53における液晶層の長軸方向を基板面内で0°から45°に変化する。液晶層53では、入射光の偏光方向と液晶分子の長軸方向とが45°ずれており、液晶のリタデーションがλ/2に設定されているので、液晶層53に入射した横方向の直線偏光は、縦方向の直線偏光となって第1偏光板51に入射する。従って、透過領域56では、第1偏光板は、第2偏光板52に通過したバックライト光を通過させて、白表示となる。
以上のように、透過領域では電圧無印加で黒表示、電圧印加状態で白表示となるノーマリーブラック表示となる。
Torque=(εE×n)×n=ε0εaEsin(θ)cos(θ)
(ea:誘電率異方性)
のトルクがかかる。ここで、電界の方向は、くし歯電極に直交する方向であり、ラビング方向と櫛歯電極とがなす角をα(以下、ラビング角)とすると、θ=90°−αとなる。
