Abstract:
A lens array includes arranged lenses. Each of at least two adjacent lenses in the lens array includes a first region located at and around an optical axis of the lens and having a first curvature, and a second region located farther away from the optical axis than the first region and having a second curvature. The second curvature is larger than the first curvature.
