Abstract: A unisometric reflection display having a light transmissivity includes reflectors included in a reflector holding layer of a thin film form. The reflectors incline at a fixed direction and a fixed angle to a plane of the reflector holding layer. Light incident from a first direction is reflected on a front surface of a reflector to be inhibited from transmitting through the reflector holding layer. Light incident from a second direction to a reflector is reflected on a front surface of the reflector and a rear surface of another reflector adjacent the reflector at a front surface side, or reflected this way a plurality of times to transmit through the reflector holding layer.

Abstract: A multiple-image display body includes a spacer layer, a line tone barrier layer stacked on the first surface of the spacer layer, and a multiple-image formation layer stacked on the second surface of the spacer layer. The line tone barrier layer includes first regions, which transmit electromagnetic waves, and second regions, which absorb electromagnetic waves. The multiple-image formation layer includes images that are visible when observed from specific angles over the first regions of the line tone barrier. The image is formed by a contrast resulting from an area ratio of the third region, which scatters electromagnetic waves, and the fourth region, which absorbs electromagnetic waves.

Abstract: A unisometric reflection display has a light transmissivity and includes reflectors included in a reflector holding layer of a thin film form. The reflector holding layer has a plurality of sections divided in a direction of a plane of the reflector holding layer. In each of at least two of the sections, reflectors inside incline in a fixed direction and a fixed angle. A direction and/or an angle in which reflectors incline differ between the two sections.

Abstract: A display member according to this invention includes a plurality of pixels. At least one of the plurality of pixels includes a relief structure formation layer including a first region configured to display a predetermined color on a condition, and a second region different from the first region, a first layer made of a first material, and covering at least the first region, and a second layer made of a second material different from the first material, and covering the first layer. The display member displays an image based on a distribution of the first region on the condition that the display member is observed in the oblique direction, and displays an image based on a distribution of the second region on a condition that the display member is observed with transmitted light.

Abstract: This invention aims to provide a novel laminate in which a first layer is formed with high positional accuracy, and to provide a manufacturing method thereof. In the laminate of this invention, a relief structure forming layer includes a first region having an indented structure extending in a first direction or a direction tilted by an angle within 10 degrees to the left or right from the first direction in a plan view, and a second region including an indented structure extending in a second direction orthogonal to the first direction or a direction tilted by an angle within 65 degrees to the left or right from the second direction in a plan view. The first layer contains a first material which is different from a material of the relief structure forming layer, and has a surface shape corresponding to that of the relief structure forming layer.

Abstract: An optical element includes a transmission diffraction portion, which reflective portions and transmissive portions. The reflective portions are arranged at equal intervals along a given axis. Each reflective portion reflects light included in the visible light. The light reflected by the reflective portions forms a reflection image. The transmissive portions transmit the visible light. Each transmissive portion is sandwiched by two corresponding reflective portions that are adjacent to each other along the given axis. At least part of each reflective portion forms the reflection image by rendering a reflection angle of the light reflected by the reflective portions different from an angle of light incident on the reflective portions. The transmission diffraction portion forms diffracted images having different colors with diffracted light that is produced by diffracting light transmitted through the transmissive portions in a predetermined direction.
