Abstract: An anti-counterfeit medium includes a portion having optical transparency, a retardation layer facing the portion and including regions whose slow axis directions are different from each other, and a polarizing layer facing the retardation layer at a position of the portion. The anti-counterfeit medium includes only the polarizing layer as a polarizer. A portion out of the anti-counterfeit medium where the portion, the retardation layer, and the polarizing layer form a stacked structure has optical transparency.

Abstract: A display includes a first optical effect layer including a first interface part, the first interface part being provided with recesses or protrusions arranged two-dimensionally at the minimum center-to-center distance in a range of 200 nm to 500 nm, each of the recesses or protrusions having a forward-tapered shape; a reflective material layer covering at least a part of the first interface part; and a second optical effect layer including, at a position of a first portion of the first interface part that is covered with the reflective material layer, a portion that faces the reflective material layer with the first optical effect layer interposed therebetween or faces the first optical effect layer with the reflective material layer interposed therebetween, the second optical effect layer containing at least one of a cholesteric liquid crystal, a pearl pigment and a multilayer interference film.
