PROBLEM TO BE SOLVED: To provide an optical element array having high light-condensing efficiency.SOLUTION: The optical element array includes a first optical element located away from the center by a first distance. The first optical element has a first width, a first height, and a first curvature radius, in a first position and a second width, a second height, and a second curvature radius, in a second position. The first width is larger than the second width, the first height is higher than the second height, and the first curvature radius is smaller than the second curvature radius. 【課題】 高い集光効率の光学素子アレイを提供する。【解決手段】 光学素子アレイにおいて、中心から第１の距離だけ離れて位置する第１の光学素子を含む。第１の光学素子は、第１の位置における第１の幅と、第１の高さと、第１の曲率半径を有し、第２の位置における第２の幅と、第２の高さと、第２の曲率半径を有する。そして、第１の幅は第２の幅よりも大きく、第１の高さは第２の高さよりも高く、第１の曲率半径は第２の曲率半径よりも小さい。【選択図】 図２
