1. A display comprising:
a first light-scattering region provided with first linear protrusions or recesses having the same longitudinal direction and each configured to emit white scattered light in a plane perpendicular to the longitudinal direction when illuminated with white light in a direction normal to the first light-scattering region, the first linear protrusions or recesses being discontinuous in the longitudinal direction thereof; and a second light-scattering region provided with second linear protrusions or recesses having the same longitudinal direction different from the longitudinal direction of the first linear protrusions or recesses and configured to emit white scattered light in a plane perpendicular to the longitudinal direction of the second linear protrusions or recesses when illuminated with white light in a direction normal to the second light scattering region, the second linear protrusions or recesses being discontinuous in the longitudinal direction thereof, wherein the first light-scattering region forms an image and the second light-scattering region forms a marginal part of the image, the marginal part of the image extending along the entire perimeter of the image formed by the first light-scattering region, wherein in at least one of the first and second light-scattering regions, the linear protrusions or recesses are arranged at random, wherein the first light-scattering region includes an array of cells, each provided with the first protrusions or recesses wherein the second light-scattering region includes an array of cells, each provided with the second protrusions or recesses, and wherein in at least one of the first and second light-scattering regions, the cells included in the light-scattering region include first and second cells different from each other in at least one of length and width of the protrusions or recesses, the first and second cells being configured to emit the scattered light at first and second degrees of divergence, respectively, such that an image informed by the first and second cells is seen as an image with light and shade. |
