A screen includes a plurality of structures arrayed in parallel in at least one direction of a first direction and a second direction perpendicular to the first direction on a reference surface parallel to the first direction and the second direction. The structures are arrayed such that at least one of a distance between central positions of the structures adjacent to each other and a size of the structure changes irregularly in at least one direction, in which the structures are arrayed in parallel, of the first and second directions.
