Abstract: A dielectric layer comprising an embossed surface and a flat surface which is located at a side opposite to the embossed surface is provided. The plane that approximates the flat surface is the X-Y plane, and the normal direction to the X-Y plane is the Z direction. The embossed surface has inclined surfaces that are inclined with respect to the Z direction, and the inclined surfaces reflect incident light incident on the dielectric layer and emerge reflected light. The elevation angle, which is an angle between the inclined surface and the X-Y plane, is α. The refractive index of the dielectric layer is n. These values satisfy Formula (1): sin α≤(1/n)

Abstract: An optical film including a recording surface on which a plurality of unit blocks is disposed at regular intervals. For these unit blocks, phase components of light from a reconstruction point are calculated. The recording surface includes a calculated element region provided with an array of the unit blocks for which phase components of light from the reconstruction point are calculated for reproduction of an image. A first image is a monotone reconstruction image having even brightness, and a second image is a grayscale image having brightness gradation.

Abstract: An organic EL (electroluminescent) device includes a translucent substrate, a transparent electrode, a luminescent layer, and a cathode placed over one surface of the translucent substrate, and a light extraction film having unevenness placed on the other surface. The surface of the cathode facing the luminescent layer has a plurality of recesses or protrusions. The Fourier transform image of the surface of the cathode facing the luminescent layer has a surface plasmon absorption suppression area including a spatial frequency v obtained from Eq. (I) and a light scattering area not including spatial frequencies equal to or greater than the spatial frequency v.

Abstract: A display body includes a display surface including a plurality of display region groups. Each display region includes at least one reflection surface that is configured to reflect light incident on the display surface toward an area including a corresponding one of reflection directions that are associated with the respective display region groups. Each display region group is configured to form an image unique to the display region group in a corresponding one of the reflection directions through reflection of light on the reflection surfaces in the display region group. The display region groups are configured to form, in two adjacent ones of the reflection directions, different images that have a interrelation between each other.
