Abstract
A multi-layered image display device for realizing a multi-layered image with a depth by overlapping a plurality of two-dimensional images includes: a display which can be selectively transparent and produce a first two-dimensional image through a combination of a plurality of pixels, a screen which is disposed behind the display so as to be overlapped in a forward-backward direction with the display; and a projector which is disposed behind the screen so as to project a second two-dimensional image on the screen. By adopting a screen and a projector instead of a rear display and a backlight unit, the cross stripes of the rear display can be removed so as to prevent the occurrence of the interference pattern (Moire phenomenon) due to the interference of different pixel patterns, and an additional diffuse layer can be omitted so that an assembling process of the multi-layer image display device can be simplified.
