The invention discloses a three-dimensional display device and a manufacturing method thereof; the device comprises a liquid crystal grating and a monitor which are stacked, and a polaroid which is arranged between the monitor and the liquid crystal grating; the polaroid is an internal polaroid of the monitor or an external polaroid; the liquid crystal grating comprises a liquid crystal grating electrode array and a liquid crystal grating liquid crystal layer; and the distribution direction of the liquid crystal molecules of the liquid crystal grating liquid crystal layer is in parallel with the optical axis direction of the polaroid. The distribution direction of the liquid crystal molecules of the liquid crystal grating liquid crystal layer is in parallel with the optical axis direction of the polaroid; and when incident light enters the liquid crystal grating through the polaroid, no component of the optical axis of e light exists on the liquid crystal molecules, so that the three-dimensional display cross-talk is effectively reduced.
Description
technical field [0001] The invention relates to the display field, in particular to a stereoscopic display device and a manufacturing method thereof. Background technique [0002] Liquid crystal materials are widely used in various fields of 3D display, such as 2D / 3D switching, 3D liquid crystal slits and liquid crystal lenses, all of which utilize the variability of the refractive index of liquid crystal molecules. The alignment direction of liquid crystal molecules is closely related to the polarization direction of incident light. For liquid crystal molecules with the same alignment direction, incident light with different polarization directions has different refractive indices. [0003] When using liquid crystal materials as liquid crystal slits, liquid crystal lenses or 2D / 3D switching, that is, as liquid crystal gratings, the general structure of the overall 3D liquid crystal display is a laminated structure of liquid crystal gratings and liquid crystal displays super...
