Description
図10は、本発明の変形例に係る遮光部23の概略構成を表す平面図である。遮光部23は、上述した遮光部13A,13Bと同様に、マイクロレンズアレイ12の光入射側もしくは光出射側に配置されるようになっており、各マイクロレンズに対向する領域に開口が設けられている。但し、遮光部23では、その開口率が光源10に近い領域よりも光源10から遠い領域で高くなっている開口率分布を有している。例えば、図10に示したように、中央部で最も開口面積が大きく、中央部から端部にかけて徐々に開口面積が小さくなるように構成されている。このような構成においても、一つのマイクロレンズに対して一つの開口が対向配置され、また開口面積に拘らず、各マイクロレンズの平面積は一律でよい。
