PROBLEM TO BE SOLVED: To provide a display body using external light, in which not only an observation angle of the display body using external light can be flexibly designed with respect to a predicted incident angle of external light, but constant display characteristics can be stably maintained even when an incident angle of external light changes, and excellent uniformity is achieved in the luminance of display light within a viewing angle.SOLUTION: The display body using external light comprises a laminate of a reflector having a sawtooth pattern and a light-diffusing film. The reflector having a sawtooth pattern has a sawtooth structure that forms a continuous body of a plurality of tooth shape structures in at least one cross section in a thickness direction, and has a plurality of reflection regions in at least a part of the sawtooth structure. The light-diffusing film has such an inner structure in the film that a plurality of regions having a relatively high refractive index is included in a region having a relatively low refractive index. |
