Claim:
1. A multi-layer image display device for realizing a multi-layered image with a depth by overlapping a plurality of two-dimensional images, comprising: a liquid crystal display device which can be selectively transparent and produce a first two-dimensional image through a combination of a plurality of pixels, a plurality of screens disposed behind the liquid crystal display device so as to be overlapped in a forward-backward direction with the liquid crystal display device; and a projector which is disposed behind the plurality of screens that is disposed behind the liquid crystal display device, so as to project a second two-dimensional image selectively on one of the plurality of the screens, wherein the plurality of the screens are selectively turned on, and the projector is synchronized with the plurality of the screens such that the projector is selectively focused on a turned-on screen of the plurality of the screens, wherein the liquid crystal display device has a first side facing the plurality of screens and a second side opposite to the first side, and the liquid crystal display device is selectively transparent, and both the first two-dimensional image displayed on the liquid crystal display device and the second two-dimensional image displayed on the turned-on screen are simultaneously seen from a same direction from the second side, wherein the projector provides a backlight to the liquid crystal display device, and wherein the liquid crystal display device, the screens and the projector providing the backlight are disposed in this order, and the backlight produced by the projector passes through the screens and then illuminates the liquid crystal display device to produce the first two-dimensional image on the liquid crystal display device, with the screens being disposed between the first two-dimensional image and the projector providing the backlight.
