Abstract: Embodiments of the invention disclose a liquid crystal display device and a method for manufacturing the same. The liquid crystal display device comprises: a color filter substrate including a first transparent substrate; and an array substrate including a second transparent substrate, wherein the first transparent substrate has a first transparent magnetic film layer formed thereon, the second transparent substrate has a second transparent magnetic film layer farmed thereon, and the first transparent magnetic film layer and the second transparent magnetic film layer have the same magnetism.

Abstract: A 3D display device and an operating method thereof, the 3D display device comprising: a display screen (10), for displaying two-dimensional left and right eye pictures; a magnetic field device (20), disposed right in front of the display screen (10) on a light emitting side of the display screen and generating a magnetic field having a varying frequency in synchronization with a refresh frequency of the two-dimensional left and right eye pictures of the display screen (10), thus rotating a direction of a polarization plane of polarized light emitted from the display screen (10).

Abstract: An active-shutter 3D glasses and an operating method thereof, the active-shutter 3D glasses comprises: a frame comprising temples; left and right magneto-optical eyeglasses, supported by the frame, and comprising left and right transparent mediums and left and right rear polarizers, respectively; a magnetic field apparatus, located outside the left and right magneto-optical eyeglasses, and providing the left and right magneto-optical eyeglasses with a magnetic field which causes polarization planes of polarized light entering the left and right magneto-optical eyeglasses to rotate; and a signal module, connected with the magnetic field apparatus, and providing a electric-current signal to the magnetic field apparatus so that the magnetic field corresponds to the electric-current signal.
