Abstract

The present invention relates to a projection display device and a wall display system. More particularly, the present invention relates to a projection display device, which is able to prevent gap between images at a screen edge of each of projection display devices and to minimize the thickness of each screen of the projection display devices in case plural projection display devices are multilayered to form a large wall display system, and a wall display system using the same.
