Abstract

An optical element array includes a plurality of optical elements arranged along a first direction and a second direction. A first optical element is included at a position distanced from a center of the optical element array by a first distance. The first optical element has a first width, a first height, and a first curvature radius at the first position, and a second width, a second height, and a second curvature radius at a second position. The first width is wider 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. The first position and the second position are taken along a single direction.
