  • Patent number: 8885123
    Abstract: The present invention provides a 3D display apparatus which comprises a display and a liquid crystal cell module. The liquid crystal cell module retards a phase of the light emitted from the display and corresponding to a display frame for forming a left-handed circularly polarized light and a right-handed circularly polarized light. The present invention further provides a method for manufacturing the 3D display apparatus. The present invention can display 3D images without losing image information. The response time of a ferroelectric liquid crystal and an anti-ferroelectric liquid crystal of the present invention is faster, and thus the effect on the luminance of the display is less.
