ABSTRACT:
An optical element includes a plurality of first beam bodies arranged in a first direction on a first plane and being parallel to each other, and second beam bodies placed between adjacent ones of the first beam bodies and provided parallel to the first beam bodies. The first beam body has side surfaces which face the second beam bodies adjacent thereto and are sloped so that the width in the first direction gradually decreases to the upward direction perpendicular to the first plane, the second beam body has side surfaces which face the first beam bodies adjacent thereto and are sloped so that the width in the first direction gradually increases to the upward direction perpendicular to the first plane, and as viewed in the first direction, the spacing between the first beam body and the second beam body is variable.
