DISPLAY AND LABELED ARTICLE

摘要

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.

1. A display comprising:
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, wherein the first optical effect layer further includes a second interface part as a flat surface that is adjacent to the first interface part, wherein the reflective material layer further covers a part of the second interface part, wherein a first display part of the display that corresponds to the first interface part allows the observer to recognize a second optical effect offered by the second optical effect layer when observed at an angle capable of observing regularly reflected light, wherein when the Illumination light is Incident at an angle within the negative angular range and the display is observed at an angle within the negative angular range, the first display part allows the observer to recognize the diffracted light from the first interface part, and wherein the display further comprises a dark light-absorbing layer facing the second optical effect layer with the first optical effect layer interposed therebetween at a portion of the second interface part is not covered with the reflective material layer.
