Abstract
A reflective plate comprises a substrate, a plurality of protrusions each formed on the substrate and having a curved surface, and a reflective film formed on the substrate having the protrusions, wherein a planar shape of each of the protrusions is indefinite, and when a frame line of the planar shape of each of the protrusions is divided into fine line segments, the line segments are pointed in all directions or in predetermined directions. This improves reflective properties such as dispersion properties.
