Abstract
An optical elementincludes a first layer (A) and a second layer (A) that faces the first layer (A). The first layer (A) includes a plurality of first structural bodies (B) that each have optical anisotropy. In reflection of light entering from the first layer (A), the second layer (A) reflects the light while maintaining a polarization state of the light at incidence and at the reflection. The first layer (A) changes, according to directions of orientation of the first structural bodies (B), a phase of the light from a phase at incidence to the first layer (A) from outside of the first layer (A) to a phase at output from the first layer (A) toward the second layer (A). The first layer (A) changes the phase of the light from a phase at incidence to the first layer (A) from the second layer (A) to a phase at output from the first layer (A) toward the outside of the first layer (A) according to the directions of orientation of the first structural bodies (B).
