A 3D image display apparatus featuring a new polarization system is introduced which minimizes crosstalk between stereoimages. The polarization system includes a shutter panel that shifts the phase of an incident light, a polarizing film disposed between the shutter panel and an observer, a first retardation film disposed between the shutter panel and the polarizing film, a second retardation film disposed between the polarizing film and the first retardation film to correspond to the left eye of the observer, and a third retardation film disposed between the polarizing film and the first retardation film to correspond to the right eye of the observer.
