| Zusammenfassung: | The invention discloses a 3D display device with high resolution and a wide viewing angle. The 3D display device comprises a display screen, a gradually-changed aperture polarization slit grating I and a gradually-changed aperture polarization slit grating II. The interval width of the adjacent light-transmitting slits I corresponding to the same image element is greater than the aperture width of the light-transmitting slit II between the adjacent light-transmitting slits I; a part of light emitted by each image element passes through the gradually-changed aperture polarization slit grating I and is modulated into polarized light I with the same polarization direction by the gradually-changed aperture polarization slit grating I, the polarized light I is projected to an imaging space through the light-transmitting slit II corresponding to the image element, and a 3D image is reconstructed; a part of light emitted by each image element passes through the light-transmitting slit I corresponding to the image el |
