Abstract

A forgery-prevention technique for achieving a high forgery-prevention effect can be realized. A display (1) includes light-scattering regions (20a, 20b) each provided with linear protrusions and/or recesses having the same longitudinal direction. The light-scattering regions (20a, 20b) are different from each other in the longitudinal direction.

Claims (15)

1. A display comprising light-scattering regions each provided with linear protrusions and/or recesses having the same longitudinal direction, the light-scattering regions being different from each other in the longitudinal direction.
2. The display according to claim 1, wherein it comprises the light-scattering regions in the same plane.
3. The display according to claim 1, wherein the light-scattering regions display images, respectively, and the images are distinguishable from each other with an unaided eye.
4. The display according to claim 1, wherein each of the light-scattering regions includes an array of cells each provided with the protrusions and/or recesses.
5. The display according to claim 4, wherein in at least one of the light-scattering regions, the cells included in the light-scattering region include cells different from each other in length and/or width of the protrusions and/or recesses.
6. The display according to claim 1, wherein in at least one of the light-scattering regions, the linear protrusions and/or recesses are arranged at random.
7. The display according to claim 1, wherein in at least one of the light-scattering regions, the linear protrusions and/or recesses have the same length and width.
8. The display according to claim 1, wherein in at least one of the light-scattering regions, an average interval among the protrusion and/or recesses is equal to or smaller than 10 µm.
9. The display according to claim 1, wherein the light-scattering regions include two light-scattering regions having the longitudinal directions orthogonal to each other.
10. The display according to claim 1, further comprising a diffraction grating region provided with a relief structure which forms a diffraction grating.
11. The display according to claim 10, wherein each of the light-scattering regions includes an array of cells each provided with the protrusions and/or recesses, and the diffraction grating region includes an array of cells each provided with the relief structure.
12. The display according to claim 11, wherein in at least one of the light-scattering regions, the cells included in the light-scattering region include cells different in at least one of density, size, shape, and depth or height of the protrusions and/or recesses, and an area ratio of a portion provided with the protrusions and/or recesses with respect to the cell, and the cells included in the diffraction grating region include cells different in at least one of spatial frequency, orientation, and depth or height of grooves forming the diffraction grating, and an area ratio of the diffraction grating with respect to the cell.
13. The display according to claim 1, further comprising a light-scattering region provided with protrusions and/or recesses having planar shapes of circles, ellipses or polygons.
14. The display according to claim 1, wherein the light-reflecting regions are regions included in a main surface of a layer made of a light-transmitting material, and the display further comprises a reflective layer or a semitransparent reflective layer covering the main surface.
15. A labeled article comprising:

the display according to any one of claims 1 to 14; and an article supporting the display.
