- 照射された光を受けて透過または遮光させるときに当該光に循環的な偏向を生じさせる光偏向手段と、前記光を3原色に分離して3つのホールド型表示素子に各々導く色分離手段と、各ホールド型表示素子を経て得られる各色映像光を合成して投写する投写手段と、各ホールド型表示素子に画素駆動信号を与える素子駆動手段と、を備える投写型映像表示装置において、
各ホールド型表示素子上で当該素子よりも小さな面積で集光される各色光が循環的にスクロールされるように構成されており、
前記光偏向手段は、1回循環するあたり単一のスクロール光を生成する単一の渦状の透過部を有する光偏向要素を備えることを特徴とする投写型映像表示装置。 - 前記画素駆動信号に同期した周期にて前記光偏向手段の循環を制御する光偏向制御手段と、前記画素駆動信号に同期したパルスにて光源を駆動させることで、前記光偏向手段の循環の周期とも同期させて駆動させる光源駆動手段とをさらに備えることを特徴とする請求項1に記載の投写型映像表示装置。
