Abstract

An image display according to an embodiment includes a first image-displaying portion that displays first information about a certain object as a first image of object color, and a second image-displaying portion that displays second information about the object as a second image of structural color provided by a relief structure, the relief structure including at least one structure selected from the group consisting of diffraction grating, hologram, and light-scattering structure having an anisotropic light-scattering property. According to an example, the object is a person, and the first image includes a facial image of the person. A labeled article according to another embodiment includes the image display, and a substrate supporting the image display.

First claim

What is claimed is:

1. An image display comprising:
a first image-displaying portion that displays first information about a certain object as a first image of object color;
a second image-displaying portion that displays second information about the object as a second image of structural color provided by a relief structure, the relief structure including at least one structure selected from the group consisting of diffraction grating and hologram; and
an underlayer, the second image-displaying portion being provided on the underlayer, wherein
a reflection layer is formed on at least a part of a surface of the relief structure, the reflection layer being made of metal, metal oxide, or intermetallic compound,
the second image-displaying portion is made of a plurality of dot-shaped portions arranged in a two-dimensional manner,
the object is a person, the first image includes a facial image of the person, and the second image includes a same facial image as the facial image included in the first image, and
each of the dot-shaped portions includes:
a relief structure formation layer facing the underlayer and having the relief structure on a surface thereof that faces the underlayer,
the reflection layer at least partially covering the relief structure, and
an adhesive layer interposed between the reflection layer and the underlayer.
