摘要： A 3D image display device includes an image projection unit for projecting a first image; a first polarization unit disposed on a projection path of the first image for linearly polarizing the first image to have a first linear polarization direction; a lens array disposed on the projection path of the first image for refracting an image having a second linear polarization direction, the second linear polarization direction being different from the first linear polarization direction; a first quarter-wave plate disposed on the projection path of the first image for converting polarization direction of an image between a linear polarization direction and a circular polarization direction; and a reflection unit disposed on the projection path of the first image for reflecting the first image transmitted from the first quarter-wave plate back to the first quarter-wave plate.
