Abstract
The embodiments of the present disclosure provide a liquid crystal grating, a 3D display device, and a driving method thereof, relating to the field of display technology, and improving the 3D display effect. The liquid crystal grating includes a first substrate and a second substrate disposed opposite to each other, a liquid crystal layer and a plurality of spacers, the liquid crystal layer and the plurality of spacers being disposed between the first substrate and the second substrate, the liquid crystal grating is configured to form alternating light transmitting regions and dark state regions if power is applied, along a first direction perpendicular to an extending direction of a light transmitting region, the plurality of spacers are arranged with a period, a width of the light transmitting region is a positive integer multiple of the period.
