High-resolution 3D display device with uniform resolution

The invention discloses a high-resolution 3D display device with uniform resolution. The high-resolution 3D display device comprises a display screen, a polarization rectangular pinhole array I and a polarization rectangular pinhole array II. The interval width of the adjacent rectangular light-transmitting pinholes I corresponding to the single rectangular image element is greater than the horizontal aperture width of the rectangular light-transmitting pinholes II between the adjacent rectangular light-transmitting pinholes I; a part of light emitted by each rectangular image element passes through the polarization rectangular pinhole array I and is modulated into polarized light I with the same polarization direction by the polarization rectangular pinhole array I, the polarized light I is projected to an imaging space through the rectangular light-transmitting pinhole II corresponding to the rectangular image element, and a 3D image is reconstructed; a part of light emitted by each rectangular image elemen
