Abstract
A liquid crystal element () includes helical structures (). The liquid crystal element () has a light incidence surface () on which light is incident and a reflective surface () which reflects the light coming through the light incidence surface (). Each helical structure () includes structure units (). Each structure unit () includes liquid crystal molecules () stacked in a twisted manner to form a helix. A second end (E) of one structure unit () of structure units () adjacent to one another in a first direction (A) serves as a first end (E) of the other structure unit (). Directions of orientation of the liquid crystal molecules () at the first ends (E) included in the helical structures () are identical. The reflective surface () includes at least one of the first ends (E) included in each helical structure (). The reflective surface () is non-parallel to the light incidence surface ().
