Zusammenfassung:	The present disclosure provides a liquid crystal grating, a display device and a driving method. The liquid crystal grating of the present disclosure may include a plurality of grating element groups for forming dark fringes and transparent fringes. The dark fringe of each grating element group may be arranged adjacent to a transparent fringe of a neighboring grating element group. Each grating element group may include a plurality of first grating elements and at least one second grating element arranged parallel to each other. At least one of the first grating elements is transparent so as to form the transparent fringe of the grating element group, and different first grating elements are enabled to be transparent so as to change positions of the transparent fringes. The second grating element is opaque, the first grating elements and the second grating element that are opaque may be used to form the dark fringes of the grating element group, and the second grating element may have a width greater than that of each of the first grating elements. The liquid crystal grating with movable slit position according to the present disclosure can prevent a short circuit and a line defect due to an excessive number of the electrodes in the prior art.
