Abstract
A display body includes lattice lines that are arranged along a plane of incidence on which light is incident. The lattice lines have properties for forming a bright image with diffracted light of the incident light in an oblique view in which the plane of incidence is viewed obliquely, and absorbing some of the incident light. The surface of each of the lattice lines includes dispersed fine step parts that are repetitive in the direction in which the lattice lines extend. The steps have an antireflection function and form a dark image in a front view directly facing the plane of incidence.
