突出したライン状のパターンを有するフィルムを製造できる金型内に透明アクリル樹脂を充填し、図2に示すような突出したライン状パターンを有するフィルムを製造した。前記フィルム上に金(Au)を蒸着した後、斜面以外の部分に蒸着されている金(Au)を、イオンミリング法により除去した。パターンの具体的な寸法は、下記表1に示す通りである。
実施例1〜27に対して、視野角ごとの透過率(%)を測定し、その結果を下記表1に示した。視野角は、図5に示すように、フィルムに対して垂直な方向を「0°」と定義した。また、図5において、フィルムに対する垂直線から、左側に45°の方向を「−45°」、右側に45°の方向を「45°」、と、それぞれ定義した。視野角ごとの透過率(%)とは、光制御フィルムの前記他方の面からフィルムに対して垂直に照射した光について、前記の「0°」、「−45°」、「45°」の各方向から見た場合の透過率(%)を表す。
