摘要： PROBLEM TO BE SOLVED: To solve a problem in conventional stereoscopic image displays using diffraction gratings, in which interference patterns are formed in an arc-like shape to allow stereoscopic view in various directions, such that, since reflected light is dispersed in various directions, entire brightness is low.SOLUTION: A stereoscopic image display device including diffraction gratings comprises: an emphasizing portion 3 of the stereoscopic image display device is constituted of a cell 6 of diffraction gratings constituted of a parallel linear concave portion or convex portion; and a cell 5 of diffraction gratings constituted of arc-shaped concave portion or convex portion. And a non-emphasizing portion is constituted of a cell 5 of diffraction gratings constituted of arc-shaped concave portion or convex portion. In the emphasizing portion, the ration between the area of the cells of diffraction grating constituted of arc-shaped concave portion or convex portion and the area of the cells of diffraction grating constituted of parallel and linear concave portion or convex portion is within a range of 7:3 to 3:7.

摘要： PROBLEM TO BE SOLVED: To provide an image display medium which can display a multi-color image giving a natural impression, while maintaining anti-copying function, by taking the advantages of a diffraction grating which gives rise to a color change in compliance with a viewing angle. SOLUTION: This image display medium reveals a multi-color image by dividing a transparent sheet into a plurality of areas, then arranging a monochromatic image or an image of a plurality of colors obtained by superposing monochromatic images in each of the areas, and laminating a plurality of the monochromatic images over each other. In this case, some of the monochromatic images selected from among the monochromatic images or the monochromatic images making up the images in a plurality of colors, are constituted using the diffraction grating. On the other hand, the other images are colored in a coloring agent. Color change occurrs only in the monochromatic image constituted using the diffraction grating, even if the viewing angle is changed, and no color change takes place in the other monochromatic image. Thus it is possible to display a multi-color image giving a natural impression, even if the viewing angle is not strictly specified. Since the duplicated image of this multi-color image reveals no color change, even if the viewing angle is changed significantly, it is possible to easily distinguish between the genuine image and the duplicated image.

摘要翻译：要解决的问题：提供一种能够显示产生自然印象的多色图像同时保持反复制功能的图像显示介质，通过采用引起颜色变化的衍射光栅的优点符合视角。解决方案：该图像显示介质通过将透明片分成多个区域来显示多色图像，然后布置单色图像或通过在每个区域中叠加单色图像而获得的多种颜色的图像，并且将多个单色图像彼此层叠。在这种情况下，使用衍射光栅构成从单色图像中选择的一些单色图像或构成多种颜色的图像的单色图像。另一方面，其他图像被着色在着色剂中。只有在使用衍射光栅构成的单色图像中才出现颜色变化，即使观察角度发生变化，也不会在其它单色图像中发生颜色变化。因此，即使没有严格规定视角，也可以显示给出自然印象的多色图像。由于该多色图像的复制图像不显示颜色变化，即使视角发生显着变化，也可以容易地区分真实图像和复制图像。版权所有（C）2011，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a light-scattering device which is hardly forecasted to include two quite different images inside a single device itself, and to provide a light-scattering material, an image-display medium and a package. SOLUTION: In the light-scattering device, the surface of a base material is divided into at least a first region to a fourth region. The first and second regions are formed of light-scattering elements, having anisotropy in a straight direction and are arranged so that intensity distributions of scattering light may be straight to each other. Light-scattering elements which are equivalent in scattering-light intensity are formed in the third region, as viewed from the directions in which the intensity distributions of scattered light by the light-scattering elements formed in the first and second regions are high. Light-scattering elements which are equivalent in the scattering-light intensity are formed in the fourth region, as viewed from the directions in which the intensity distributions of scattered light by the light-scattering elements formed in the first and second regions are low. The image-display medium and the package are also provided. COPYRIGHT: (C)2011,JPO&INPIT
