Abstract
An optical element comprises an organic resin and bubbles distributed to have a number density increasing from a first plane of the optical element toward a second plane of the optical element, where a diameter of the bubbles is less than or equal to a wavelength of light which enters the optical element. At least one of the first plane and the second plane may have an uneven structure.
