The authors propose a stereovision 3D-display system using holographic optical element (HOE). The HOE of this system is used for holographic screen. Each parallax image is projected onto this screen overlap each other and is distributed to each view area by diffraction quality of HOE. Because observer can see 3D-images. This system uses many LCD that number is equal to viewpoints. Because even if the number of viewpoints increase, resolution of each viewpoint isn't decline. The viewpoint of this system is wide focus, because observer can see 3D image freely. Observer doesn't fix his face and eye.
