Abstract
The present invention relates to a 3-dimensional video display device using a single image source for background image and object image display, which uses a double Fresnel lens structure, multi-reflector, and half mirror part. In particular, the present invention relates to a 3-dimensional image device with which the problem in prior art of spatial size in obtaining a background image is resolved, and with which a background image of a large display and a 3-dimensional image having an enhanced sense of depth and a large image are displayed simultaneously using only a single image source.
