Abstract
【解決手段】45°より大きく、90°より小さい(標準的な角度は85°)高プレチルトをもたらす第1配向面(12)を備えていることを特徴とする液晶装置である。このプレチルトは、ある所定の方向に向いており面(12)と平行な成分を有している。第2配向面(13)は45°より小さく、0°より大きい(標準的な角度は5°)低プレチルトをもたらす。この低プレチルトは、上記所定の方向に向いており第2面(13)と平行な成分を有している。液晶材料層は上記第1面(12)と、上記第2面(13)との間に配置されている。
【選択図】図1
Description
プレチルト約85°の高プレチルト配向層
プレチルト約5°の低プレチルト配向層
2周波LC
セル厚対ピッチ(d/p)比が約0.1のカイラルドーパント
図5は、図3もしくは図4に示される装置の例で得られるプライバシーの測定値と、NTTDocom SH902iとして知られる製品で使用されるECBモードとを比較する図である。この図はプライバシーの強さを、プライバシーが最大である面におけるポーラー角の機能として示している(すなわち、ラビング方向と、基板に対して垂直である面)。スプレイ−ツイストモードは、軸外の角度の幅広い範囲において、プライバシーの測定基準が高い。プライバシー測定基準とは、パブリック(広視野)輝度をプライベート(狭視野)輝度で割った、コントラスト比として定義されている。NTTDocom SH902i製品で使用されているECBセルは、ラビング方向がそれぞれ非平行になって配列されている、二つの低プレチルト基板(θ<15°)から構成されている。すなわち、スプレイ−ツイストモードとは、配向条件が実質的に違う。外面電界によって切り替えても、ECBセルのダイレクタがねじれ構造を形成することはない。それゆえ、コストの高い内面電極を加えないかぎり、ECBを使ってミラーモードや、裸眼立体3Dモードを生成することはできない。
