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. |
