An image display comprising: a first image-displaying portion (I1a) that is configured to display first information about an object as a first image of object color; and a second image-displaying portion (I1b) that is configured to display 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, characterized in that the object is a person, the first image includes a face image of the person, the second image includes the same face image as the face image included in the first image, the second image-displaying portion (I1b) includes pixels each provided with a relief structure serving as at least one of hologram and diffraction grating, and each of one or more of the pixels is configured to display a microscopic image that is impossible or difficult to visually recognize when observed with unaided eyes and is visually recognizable when observing an enlarged view thereof, the second image-displaying portion (I1b) includes portions each having a shape of dot, centers of the portions each having a shape of dot are located on lattice points of a virtual planar lattice, and the portions each having a shape of dot are the pixels, wherein the microscopic image comprises at least one of a character and a symbol, the size of the character or of the symbol is within a range of 1 μm to 300 μm, and the portions each having a shape of dot are formed by thermal transfer using a thermal head. a first image-displaying portion (I1a) that is configured to display first information about an object as a first image of object color; and a second image-displaying portion (I1b) that is configured to display 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, characterized in that the object is a person, the first image includes a face image of the person, the second image includes the same face image as the face image included in the first image, the second image-displaying portion (I1b) includes pixels each provided with a relief structure serving as at least one of hologram and diffraction grating, and each of one or more of the pixels is configured to display a microscopic image that is impossible or difficult to visually recognize when observed with unaided eyes and is visually recognizable when observing an enlarged view thereof, the second image-displaying portion (I1b) includes portions each having a shape of dot, centers of the portions each having a shape of dot are located on lattice points of a virtual planar lattice, and the portions each having a shape of dot are the pixels, wherein the microscopic image comprises at least one of a character and a symbol, the size of the character or of the symbol is within a range of 1 μm to 300 μm, and the portions each having a shape of dot are formed by thermal transfer using a thermal head.
