Abstract
(EN)
The present invention provides a technology with which a display body for displaying an image of a structural color can be manufactured in a short time. This display body (1A) includes: a multilayer film (13) including a laminate that comprises two or more dielectric layers (13a, 13b) having different refractive indexes, and has one or more recesses (RR, RG, RB) on one principal surface; and one or more reflection planes that face the other principal surface of the laminate, and, when light in a visible range is incident on the multilayer film (13), causes light emitted from the other principal surface to be incident on the other principal surface at an incidence angle different from the emission angle of the light.

La présente invention concerne une technologie avec laquelle un corps d'affichage pour afficher une image d'une couleur structurale peut être fabriqué en un court laps de temps. Ce corps d'affichage (1A) comprend : un film multicouche (13) comprenant un stratifié qui comprend deux couches diélectriques ou plus (13a, 13b) ayant différents indices de réfraction, et a un ou plusieurs évidement(s) (RR, RG, RB) sur une surface principale ; et un ou plusieurs plan(s) de réflexion qui fait/font face à l'autre surface principale du stratifié, et, lorsque la lumière dans une plage visible est incidente sur le film multicouche (13), amène(nt) la lumière émise par l'autre surface principale à être incidente sur l'autre surface principale à un angle d'incidence différent de l'angle d'émission de la lumière.
