Abstract
The present invention relates to a stereoscopic image display system using polarization characteristics of a liquid crystal display panel, which realizes a stereoscopic image by disposing in an entrance pupil or in an exit pupil of a projection lens a polarization plate arranged for two polarization plates of an circular polarization opposite to each other in polarization directions or two linear polarization plates having a polarization direction of a 90 degree difference to each other to be fitted in the left and right sides on a center line, projecting left and right images of a display device panel on a screen through a projection lens in the left and right polarization directions of the polarization plate, splitting an image of the polarization plate, that is, the left and right images through viewing zones, and forming the viewing zones which can view images corresponding to the left and right eyes having the same polarization as the polarization plate. No spectacles are needed and multiple viewing points are accommodated.
