Title:
IMAGE DISPLAY DEVICE AND IMAGE DISPLAY METHOD
Document Type and Number:
WIPO Patent Application WO/2015/186789
Kind Code:
A1
Abstract:
Light rays from an image (A) are made incident to retroflective bodies formed by first and second light-reflecting surfaces (13, 14) which are orthogonal to each other and are formed with a right triangle wave shape, and third light-reflecting surfaces (15) which are orthogonal to the first and second light-reflecting surfaces (13, 14). The direction of the light reflected from the retroreflective bodies is again changed by a fourth light-reflecting surface (16), thereby focusing an image (B) at another location.
