DISPLAY BODY AND DISPLAY BODY PRODUCTION METHOD

摘要

Provided are a display body that uses structural coloration produced by a guide-mode resonant grating and has excellent hue, saturation, and brightness, and a method for producing the same. In the present invention, a grating layer comprising diffraction structures having a plurality of structural periods is provided within the region of a pixel or subpixel. This makes it possible to broaden the FWHM of the light reflected from the pixel or subpixel, and as a result, it is possible to obtain a more vivid reflection image.
