Abstract
An optical element array includes a first optical element and a second optical element that is further away from a center of an array region than the first optical element. Orthogonal projections of the first and second optical elements include first and second ends and third and fourth ends, respectively, and vertices thereof are at first and second positions. An interval between the third end and the second position is smaller than that between the first end and the first position and that between the fourth end and that second position. The first and second optical elements respectively include first and second outer edges extending from the vertices thereof to the second and fourth ends. A radius of curvature, or a median value of the radius of curvature, of the second outer edge is in the range of 80% to 120% of that of the first outer edge.
