Title:
DISPLAY BODY, TRANSFER FOIL, ADHESIVE LABEL, AND ARTICLE WITH DISPLAY BODY
Document Type and Number:
WIPO Patent Application WO/2019/167452
Kind Code:
A1
Abstract:
The present invention makes it possible to display continuously changing images over a wide range of angles without giving an observer a sense of incongruity. A display body (1) is provided with a plurality of pixels (PX) each of which includes a plurality of first subpixels (SPX1) and a plurality of second subpixels (SPX2). Each of the plurality of pixels (PX) causes each of the plurality of first subpixels (SPX1) to suppress emission of diffractive light or to emit first diffractive light within a first range of angles when the plurality of first subpixels is irradiated with illumination light in a direction normal thereto, and also causes each of the plurality of second subpixels (SPX2) to suppress emission of diffractive light or to emit second diffractive light having the same wavelength as the first diffractive light within a second range of angles greater than the first range of angles and with an intensity less than the intensity of the first diffractive light when the plurality of second subpixels is irradiated with the illumination light in the normal direction. The plurality of pixels (PX) is configured to display continuously changing images with the first and second diffractive light.
