Abstract
A method for manufacturing an optical element includes forming an optical element unit comprised of an optical material such as glass and having an outer shape of a regular triangle or a regular hexagon, arranging a plurality of optical element units two-dimensionally on a substrate so as to have a structure imitating a molecular structure of graphene or a carbon nanotube, and processing the substrate on which the plurality of optical element units are mounted into a desired surface shape.

A method for manufacturing an optical element configured for use in an aerial image display device, the method comprising:
- forming an optical element unit comprised of an optical material and having an outer shape of a regular triangle or a regular hexagon;
- arranging a plurality of optical element units two-dimensionally on a substrate;
- and,
- processing the substrate on which the plurality of optical element units are mounted into a desired non-planar surface shape such that the optical elements units are not deformed, and a boundary between the optical element units is displaced, so that the desired surface shape is provided.
