Abstract: A feature value such as a grayscale value is extracted from a design pattern on which a moiré image is based. Then, an aperture/non-aperture ratio of a moiré pattern is set according to the feature value, taking into account the specification of layers desired for a moiré image, setting of a basic pattern, and information regarding a moiré display. In addition to the aperture/non-aperture ratio, a phase shift amount and a pitch ratio can be further added to efficiently produce a moiré image having a beautiful appearance and excellent design. Moreover, such a method for generating a moiré pattern can be incorporated in a system to further improve production efficiency.

Abstract: A light reuse sheet includes: a reflection forming layer having an uneven portion including a first inclined portion and a second inclined portion; and a reflecting surface provided at a surface of the uneven portion. The light reuse sheet generates second light by reflecting first light toward a front plate, the first light being transmitted through a filling layer without being received by a light receiving face of a solar battery cell, the light reuse sheet generates third light by reflecting the second light at an interface between a light incident surface and outside of the front plate, and the light reuse sheet causes the third light to be incident to the light receiving face of the solar battery cell.

Abstract: When illumination light is externally incident on a liquid crystal display, of the incident light, light of a polarized component in one direction passes through a polarizing film to reach a liquid crystal panel. After the light reaching the liquid crystal panel is optically rotated in accordance with the display pattern displayed on the liquid crystal panel, it reaches a polarizing film. The light passing through the polarizing film enters a holographic reflector. The incident light passes through a hologram without being diffracted due to the angle selectivity of the hologram. Light passing through the hologram is regularly reflected by a metal reflective layer arranged on the back surface of the hologram to be incident on the hologram again. Incident light (reflected light) is incident on the hologram at an incident angle having a plus or a minus sign reverse to the previous incident light.
