<P>PROBLEM TO BE SOLVED: To realize a more enhanced forgery prevention effect. <P>SOLUTION: A display body includes: a first optical effect layer including, on its one surface, a first interface portion provided with a plurality of recesses or protrusions which are arranged in a two-dimentional periodic structure so as to have a minimum center-to-center distance of 200 nm to 500 nm, and then covered with a reflective material layer, a second interface portion having a flat surface covered with a reflective material layer, and a third interface portion provided with a plurality of recesses or protrusions which are arranged in a two-dimentional periodic structure different in space frequency from the first interface portion so as to have a minimum center-to-center distance of 200 nm to 500 nm, and then covered with a reflective material layer, the second interface portion being arranged in contact with both of the first interface portion and the third interface portion so as to have those common boundaries; and a second optical effect layer including a portion facing the reflective material layer via the first optical effect layer or facing the first optical effect layer via the reflective material layer, and including at least one of a cholesteric liquid crystal, a pearl pigment, and a multilayer interference film. <P>COPYRIGHT: (C)2013,JPO&INPIT |
