Original Abstract Submitted
An optical member using a metasurface structure and having high use efficiency of light. The optical member includes a substrate, a metasurface structure configured of a plurality of arrayed microstructures formed on at least one surface of the substrate, having a plurality of regions A each including, in a case where a region including one or more of the microstructures is defined as a region X, a plurality of the regions X in which phase modulation amounts are different from each other, and a phase correction layer that corrects a wavefront aberration of the metasurface structure, wherein the phase modulation amounts in the regions X of the metasurface structure gradually decrease in one direction, and the phase correction layer includes, corresponding to the region A, a region whose phase modulation amount changes.
