Abstract

There is provided an optical device including a plurality of first phasors having substantially the same phase delaying axis as each other; and a plurality of second phasors having substantially the same phase delaying axis as each other in a direction different from that of the first phasors and providing a phase difference substantially the same as that provided by the first phasors, in which the plurality of first phasors and the plurality of second phasors are arranged on substantially the same face, a density of the first phasors is substantially the same as a density of the second phasors, and a spatial distribution of the density of the first phasors and a spatial distribution of the density of the second phasors are substantially uniform.
